1. Executive Summary

Google Ads keyword match types have evolved well beyond their original literal-matching roots. As of August 2026, all three match types — broad, phrase, and exact — operate on semantic intent rather than strict text matching, which changes how you structure campaigns, manage negatives, and interpret performance data.[7] The five principles below anchor every decision in this guide.

  • Principle 1 — Intent beats text: Google matches queries based on meaning and user intent, not word-for-word keyword strings. Even exact match captures close variants and same-intent queries, so the old instinct of “build a huge exact-match list to control everything” is obsolete.[7][1]
  • Principle 2 — Broad match only works with Smart Bidding: Broad match without a Smart Bidding strategy and clean conversion tracking is a budget leak, not a growth lever. The two are designed as a pair; neither performs as well without the other.[18][6]
  • Principle 3 — Negative keywords are now the primary control mechanism: Because all match types expand by intent, negative keywords do more of the precision work that match types used to do. Maintaining shared negative lists is non-negotiable, especially with broad match active.[3][5]
  • Principle 4 — Use all three match types intentionally, not interchangeably: Best-practice 2026 structure uses exact for brand and proven high-intent terms, phrase for themed expansion, and broad as a discovery layer in a separate campaign or experiment — each serving a distinct role.[3][5][14]
  • Principle 5 — Brand controls require dedicated tools, not just match types: Brand exclusions and brand inclusions, not match type selection alone, are now the recommended mechanism for managing whether branded queries trigger your ads.[16][19]

2. Benchmarks and Numbers at a Glance

Metric Typical range or threshold Applies when Source
Exact match share of all keywords in an account 55% Observed across accounts analysed in 2026 study; sample size not stated [1]
Exact match share of impressions 27% Same 2026 study; exact drives less reach than its keyword count implies [1]
Exact match share of conversions 40% Same 2026 study; conversion yield is disproportionately high vs impression share [1]
Exact match conversion-to-impression efficiency ratio 1.48 Ratio of conversion share ÷ impression share; >1.0 means above-average conversion density; 2026 study [1]
Broad match share of impressions 46% Same 2026 study; broad dominates reach despite comprising only 25% of keywords [1]
Broad match conversion-to-impression efficiency ratio 0.76 Ratio of conversion share ÷ impression share; <1.0 means below-average conversion density; 2026 study [1]
Phrase match conversion-to-impression efficiency ratio 0.93 Between broad and exact; useful as a middle-ground indicator; 2026 study [1]
Exact match CTR 6%–8% (study); 21.66% (vendor claim) Lower figure from 2026 study; higher figure is a vendor claim — use the 6%–8% range for planning [2][12]
Broad match CTR 2%–3% (study); 8.5% (vendor claim) Lower figure from 2026 study; vendor claim likely reflects curated accounts — use 2%–3% for conservative planning [2][12]
Exact match conversion rate vs phrase match 30%–50% higher 2026 study; sample size not stated; use as directional benchmark, not a guarantee [2]
Exact match conversion rate vs broad match 50%–100% higher 2026 study; sample size not stated; most pronounced in lower-funnel, high-intent categories [2]
Minimum conversions per month for broad match to outperform phrase 50–100 conversions per campaign per month 2026 study threshold; below this volume, Smart Bidding lacks data to steer broad match effectively [2]
Healthy search-term alignment threshold 85%–90% of search terms recognisable as legitimate intent matches 2026 study; if less than 85% of search terms match intended intent, tighten negatives or shift match types [2]
Conservative budget split (exact-led) 70%–80% exact, 20%–30% phrase, 0% broad 2026 study recommendation for accounts under 50 conversions per month or with limited budgets [2]
Balanced budget split (growth-oriented) 20%–30% exact, 30%–40% phrase, 30%–50% broad 2026 study; applies only to accounts with Smart Bidding active and >50–100 conversions/month [2]
Exact match average ROAS 415% Vendor claim; sample size not stated; use as relative benchmark vs phrase (313%) and broad (277%) [12]
Exact match cost per MQL vs phrase match Exact ~2× better (approx. USD $1,200 vs USD $2,800 per MQL) Vendor claim from Optmyzr; B2B lead-gen context; not universally applicable [9]

Note: Where this table cites two conflicting figures for the same metric, the more conservative figure from the 2026 study[2] is recommended for planning purposes. Vendor claims may reflect curated or cherry-picked account samples.

3. How Keyword Match Types Work

Google Ads offers three keyword match types that control how closely a user’s search query must relate to your keyword before your ad is eligible to appear. In 2026, none of them work the way their names literally suggest — all three use semantic intent matching rather than simple text comparison.[7][1]

Match type Symbol Example keyword Will match Will not match (without negatives)
Broad match None running shoes buy trail runners, jogging trainers for women, best sneakers for marathon Theoretically: unrelated queries — but in practice the boundary is set by Smart Bidding and negatives
Phrase match “keyword” “running shoes” buy running shoes online, affordable running shoes for flat feet, shoes for running general athletic footwear, basketball boots (meaning is sufficiently different)
Exact match [keyword] [running shoes] running shoe, run shoes, shoes for running (same intent), jogging shoes trail running shoes size 10, buy running shoes cheap (added modifiers change intent)

The critical shift since the pre-2021 model is that Google no longer asks “does this query contain these words?” but rather “does this query share the same meaning or intent as this keyword?”[7][16] This affects all three match types but is most consequential for exact match, where advertisers historically expected literal text control.[1][10]

Close variants are the mechanism that enables this expansion. Google explicitly includes misspellings, singular and plural forms, stem variations, abbreviations, reordered words, omitted function words, and queries with the same meaning or intent as close variants for all three match types.[7][1] The practical implication is that negative keywords — not match type selection alone — are the primary lever for excluding irrelevant queries.[3][5]

Worked example

Exact match expansion surprises a tightly managed account

  • Setup: A Melbourne accounting software account spending $4,500 a month runs [tax software for small business] as an exact match keyword targeting high-intent buyers.
  • Numbers: Over a 4-week period the search terms report shows 38% of triggered queries are close variants such as “small business tax software,” “tax program for small businesses,” and “SMB tax software” — none of which are literal matches to the keyword string. The account’s search-term alignment is 81%, below the 85%–90% healthy threshold.[2] At a 3% average conversion rate and $45 average CPC, the 19% out-of-threshold traffic represents approximately ($4,500 × 0.19) = $855 in spend on potentially misaligned queries.
  • Decision: Add “SMB,” “program,” and “accounting software” as exact match negative keywords at the campaign level, and set a weekly 30-minute search terms review on the calendar every Monday.
  • Why: The 85%–90% alignment threshold[2] is the rule — when less than 85% of search terms map to intended intent, tighten negatives immediately regardless of match type used.

4. Broad Match

Broad match is the widest match type Google offers and, as of 2026, is designed to find searches related to the meaning of your keyword rather than the keyword itself.[7][18] It carries no symbol — you simply enter the keyword text without quotes or brackets. Despite its reputation as a budget risk, broad match is now a legitimate performance lever when the conditions are right.[5][1][3]

How broad match works in 2026

Broad match uses Google’s understanding of query intent, contextual signals, and the landing page of your ad to determine relevance — it is not a simple keyword expansion engine.[7][18][16] When paired with Smart Bidding, the system uses auction-time signals to decide whether a given broad-match query is likely to convert within your performance targets.[5][13] Without Smart Bidding, broad match has no automated quality filter and is far more likely to waste spend on irrelevant traffic.[18][6][10]

When broad match is appropriate

  • Your campaign generates at least 50–100 conversions per month, giving Smart Bidding enough data to learn which queries are likely to convert.[2]
  • Exact and phrase match campaigns have plateaued in volume and you need incremental growth.[10][16]
  • Conversion tracking is clean and reflects real business value — preferably with enhanced conversions or offline conversion imports for lead quality.[10][15]
  • You have the operational capacity to review the search terms report weekly and maintain an active negative keyword list.[4][7]
  • You can run broad match in a separate campaign or experiment, isolated from your exact and phrase campaigns.[4][14][16]

Broad match efficiency profile

Broad match accounts for 25% of keywords but 46% of impressions in a 2026 analysis, with a conversion-to-impression efficiency ratio of just 0.76 — meaning it delivers proportionally fewer conversions per impression than either phrase (0.93) or exact (1.48).[1] Its average ROAS in one vendor dataset is 277%, compared with 313% for phrase and 415% for exact.[12] These figures are not reasons to avoid broad match; they are reasons to deploy it selectively and measure its incremental value rather than its absolute ROAS in isolation.

Audience signals with broad match

Broad match benefits significantly from audience signal layering. Adding remarketing lists, Customer Match segments, and high-intent first-party audiences helps steer the system toward users who resemble your existing converters rather than any searcher whose query vaguely relates to your keyword.[11][14][15] These signals do not act as hard targeting filters but as directional inputs that improve the quality of the queries Google serves your ads against.[9][14]

Worked example

Testing broad match in an isolated campaign after exact/phrase plateau

  • Setup: A Brisbane e-commerce account selling outdoor camping equipment spends $12,000 a month. Exact and phrase campaigns have delivered a stable 320% ROAS for three consecutive months but impression share has flatlined at 62% with no meaningful volume growth. The account records 90 conversions per month across all campaigns.
  • Numbers: 90 conversions per month clears the 50–100 conversion threshold for Smart Bidding to learn effectively.[2] Broad match’s published average ROAS of 277%[12] is below the account’s current 320%, so the test budget is capped at 10% of total monthly spend = $1,200, consistent with the conservative budget split recommendation.[8] If the broad test achieves 277% ROAS on $1,200, it returns $3,324 in revenue. At the account’s existing 320% ROAS, that same $1,200 in exact/phrase would return $3,840 — a $516 gap. The test is only worth scaling if the broad campaign demonstrates incrementality (i.e., net-new conversions not cannibalised from existing campaigns).
  • Decision: Launch a separate broad match campaign with a $1,200/month budget, Target ROAS set at 280%, Customer Match audience applied as an observation signal, and a shared negative list of 47 existing account negatives ported across. Run for 6 weeks before reviewing.
  • Why: Isolating broad match in its own campaign at ≤10% of budget[8] allows incremental measurement without risking the 320% ROAS of the core exact/phrase structure.

Worked example

Broad match failing below the conversion volume threshold

  • Setup: A Perth industrial equipment supplier spending $3,000 a month runs broad match keywords across its only campaign because the account manager wants to find new query patterns. The account records 18 conversions per month.
  • Numbers: 18 conversions per month is well below the 50-conversion minimum threshold for Smart Bidding to optimise broad match reliably.[2] Broad match drives a CTR of 2%–3%[2] versus exact match’s 6%–8%[2] — at $3,000 monthly spend, switching from exact to broad could reduce effective CTR by up to 5 percentage points, meaning fewer qualified clicks at equivalent spend. With a $3,000 budget and an average CPC of $8.50, the account generates approximately 353 clicks per month; at 2% CTR (broad) vs 7% CTR (exact), the same impression volume would require nearly 3.5× more impressions to deliver the same click count.
  • Decision: Revert all keywords to exact and phrase match. Set a review trigger: only revisit broad match when the account sustains 50+ conversions per month for two consecutive months.
  • Why: Below 50 conversions per month per campaign, Smart Bidding lacks sufficient data to steer broad match, making irrelevant traffic spend near-certain.[2]

5. Phrase Match

Phrase match uses quotation marks and instructs Google to show ads for searches that include the meaning of your keyword phrase — not necessarily the exact words in the exact order.[7][2][11] Since Google’s 2021 phrase match update, which remains the foundation of today’s behaviour, phrase match absorbed the old broad match modifier functionality. It now allows reordered words, implicit concepts, and intent-equivalent queries, making it considerably more expansive than the pre-2021 version.[2][11]

How phrase match works in 2026

The key rule is that the core meaning of the phrase must be present in the query, but Google has significant latitude in deciding what “core meaning” encompasses.[7][2] A keyword like “emergency plumber Sydney” could match “24-hour plumber in Sydney,” “Sydney emergency plumbing services,” or “urgent plumber near me in Sydney” — all of which preserve the core intent of urgency, plumbing, and location.[1][11] Phrase match will generally not match queries where the intent shifts substantially, such as “plumber training courses Sydney.”

Phrase match efficiency profile

Phrase match sits between exact and broad on all major efficiency metrics. Its conversion-to-impression efficiency ratio is 0.93 — below exact (1.48) but above broad (0.76).[1] Its average ROAS in one vendor dataset is 313%.[12] Its CTR sits at 4%–5% in a 2026 study,[2] and its conversion rate is roughly 30%–50% below exact match.[2] These characteristics make phrase match well-suited to controlled expansion — capturing more query variation than exact allows while maintaining meaningfully better conversion density than broad.

When phrase match is the right choice

  • You want to expand coverage around a proven converting theme without opening the full breadth of broad match.[1][6][12]
  • Your account is below the 50–100 conversion per month threshold that broad match needs to perform reliably.[2]
  • You are targeting local service queries where the location modifier must remain intact (e.g., “plumber in Melbourne”).[1][6]
  • You are building a new campaign and want discovery with guardrails before committing to broad match.[3][5][6]

Worked example

Using phrase match to expand a local services account below the broad match threshold

  • Setup: A Sydney plumbing account spending $6,000 a month runs exact match keywords and consistently achieves 35 conversions per month — above the floor but below the 50-conversion minimum needed for broad match Smart Bidding to learn reliably.[2] The account manager wants to grow volume without the risk of broad match on thin data.
  • Numbers: Current exact match CTR is 7% (within the 6%–8% benchmark[2]), generating approximately ($6,000 ÷ $12 average CPC) = 500 clicks per month and 35 conversions at a 7% conversion rate. Adding phrase match keywords themed around “emergency plumber [suburb]” variants is projected to increase impression share by 15%, adding approximately 75 clicks at phrase match’s 4%–5% CTR[2] and a conversion rate of ~5% (30% below exact match’s 7%[2]), yielding an estimated 3–4 additional conversions per month at a cost of (75 × $12) = $900.
  • Decision: Add 12 phrase match keywords across four Sydney suburb themes at a $900/month incremental budget allocation, retaining exact match for the top 8 highest-converting terms. Review after 30 days.
  • Why: Phrase match’s 0.93 efficiency ratio[1] provides controlled expansion without the 0.76 efficiency risk of broad match, which requires ≥50 conversions to operate reliably.[2]

6. Exact Match

Exact match uses square brackets and is intended to give advertisers the highest degree of relevance control — but it is not a guarantee of literal text matching.[7][1][10] Google matches exact match keywords to queries with the same meaning or intent, including close variants, implied words, reordered words, and same-intent paraphrases.[7][1] Think of exact match as “highest relevance control,” not “lexical precision.”

Exact match efficiency profile

Exact match is the most efficient match type by every published metric. It accounts for 55% of keywords but only 27% of impressions, yet delivers 40% of conversions — producing a conversion-to-impression efficiency ratio of 1.48, compared with 0.93 for phrase and 0.76 for broad.[1] Its average ROAS in one vendor dataset reaches 415%,[12] and its conversion rate runs 50%–100% above broad match and 30%–50% above phrase match.[2] These figures explain why exact match is the default choice for brand terms, high-spend keywords, and any query where conversion quality must be protected.

When exact match is essential

  • Brand terms: Exact match on branded keywords gives the tightest control over message and spend, preventing irrelevant variations from triggering brand ads.[3][13]
  • Top-converting non-brand terms: Once a search term has proven converting performance, adding it as exact match locks in that specific intent.[5][6][10]
  • Spend protection in low-budget accounts: With a conservative budget split of 70%–80% exact,[2] exact match maximises conversion density when every dollar must count.
  • High-CPC categories: When average CPCs exceed $20–$30, the efficiency ratio advantage of exact match (1.48 vs 0.76 for broad) has outsized financial impact.[1]

Exact match limitations

Because exact match now includes close variants and same-intent queries, it may surface unexpected search terms. Advertisers who relied on exact match for total query control will find the search terms report still contains surprises.[1][7] The solution is regular search term review combined with exact match negatives, not an expectation of complete query lock-down.[3][5]

Worked example

Exact match protecting a high-CPC legal services account

  • Setup: A Sydney family law firm spending $9,000 a month operates in a category where average CPC is $35. The account runs a mix of exact and phrase match keywords. The campaign generates 28 conversions per month at an average cost per lead of $321.
  • Numbers: At an exact match efficiency ratio of 1.48 vs broad match’s 0.76,[1] exact match is approximately 1.95× more conversion-dense per impression. At $35 CPC, a 10% budget leak into irrelevant broad-equivalent queries = $900/month on low-quality traffic. Adopting a 70%–80% exact budget split[2] means $6,300–$7,200 of the $9,000 monthly spend operates at the 1.48 efficiency ratio. If exact match delivers a ROAS of 415%[12] versus broad’s 277%[12], the ROAS difference on the exact-held portion ($7,200) = ($7,200 × 4.15) − ($7,200 × 2.77) = $29,880 − $19,944 = $9,936 more in attributed revenue from the exact-match portion alone.
  • Decision: Set exact match budget allocation at 75% of total spend ($6,750/month), phrase at 25% ($2,250/month), zero broad match. Add the 12 highest-volume converting search terms as individual exact match keywords with dedicated ad groups.
  • Why: At $35 CPC, the 1.48 vs 0.76 efficiency ratio gap[1] makes exact match’s revenue premium too large to sacrifice for broad match’s discovery benefits at this account size.

7. Close Variants and Query Matching

Close variants are the mechanism by which Google expands all three match types beyond the literal keyword string. They apply to exact, phrase, and broad match and include: misspellings, singular and plural forms, acronyms, abbreviations, word stem variations, reordered words, added or removed function words (prepositions, conjunctions, articles), and queries that share the same meaning or implied intent.[7][1][10][11]

Why close variants matter strategically

Close variants mean that the old practice of building exhaustive keyword lists to “cover every variation” is largely unnecessary and inefficient — Google will match intent-equivalent queries without you listing every permutation.[1][10] Conversely, it means that match types provide less precise query exclusion than they once did, which is why negative keywords have become the primary control tool.[3][5][6]

Close variant behaviour by match type

Match type Close variants included What is NOT included
Exact match Misspellings, plurals, stems, abbreviations, reordered words, function word differences, same-meaning paraphrases Queries where intent or meaning clearly differs; additional words that change meaning
Phrase match All exact match variants plus implied words, related concepts, and intent-equivalent reformulations of the phrase Queries where the core meaning of the phrase is absent or contradicted
Broad match All of the above plus semantically related topics, synonyms, and queries Google deems relevant to the keyword’s meaning Theoretically unrelated queries — but the boundary is controlled by Smart Bidding signals and negatives

Managing close variant drift

Close variant expansion can shift over time as Google’s language models update. A keyword that matched a narrow set of variants in January 2026 may match a wider set by July 2026 without any change in your settings.[7][16] This is why weekly search term reviews are a structural requirement, not optional hygiene.[1][4][5] Monitor for:

  • New query themes appearing that were not present in previous weeks.
  • Queries that are semantically distant from your keyword appearing with increasing frequency.
  • The account’s search-term alignment score dropping below 85%.[2]

Worked example

Close variant drift reducing a phrase match account’s alignment score

  • Setup: A Gold Coast dental clinic spending $5,500 a month runs phrase match keyword “teeth whitening Gold Coast.” In January 2026 the search terms report shows 92% of queries are legitimate intent matches (above the 85%–90% threshold[2]). A July 2026 review shows the alignment score has dropped to 79% as Google begins matching queries like “teeth bleaching near me,” “cosmetic dentist Gold Coast,” and “smile makeover Gold Coast.”
  • Numbers: 79% alignment means 21% of spend ($5,500 × 0.21 = $1,155/month) is now attributable to queries outside the original intent cluster. At the phrase match conversion rate of 9.31%[12] on the aligned 79% portion, the clinic converts approximately ($5,500 × 0.79 ÷ $65 average CPC × 0.0931) = 6.2 conversions from aligned traffic. The 21% misaligned spend at an assumed 3% lower conversion rate yields only ($5,500 × 0.21 ÷ $65 × 0.0631) = 1.1 conversions — a cost per conversion of $1,050 vs $701 for aligned queries.
  • Decision: Add “bleaching,” “cosmetic dentist,” and “smile makeover” as exact match negatives at the campaign level. Add “teeth whitening Gold Coast” as an exact match keyword in a separate higher-priority campaign to recapture that query cleanly.
  • Why: When alignment drops below 85%,[2] the cost-per-conversion gap between aligned and misaligned traffic becomes large enough to require immediate negative keyword intervention.

8. Match Types with Smart Bidding

Smart Bidding and keyword match types are not independent decisions — they interact directly. The combination of match type and bidding strategy determines how much latitude Google has to serve your ads, and how well it can filter that latitude toward converting queries.[5][13][18]

The broad match + Smart Bidding pairing

Google explicitly recommends pairing broad match with Smart Bidding, framing it as the mechanism that “helps decide whether a search is likely to perform within your goals.”[5][13] This pairing works because broad match provides the query surface area, while Smart Bidding provides the per-auction quality filter. Without Smart Bidding, broad match has no automated quality gate — every related query competes for your budget regardless of its conversion likelihood.[18][6][10]

Smart Bidding strategy by match type

Match type Recommended Smart Bidding strategy Minimum data requirement Notes
Broad match Target ROAS or Target CPA; Maximise Conversions with a CPA cap 50–100 conversions per campaign per month[2] Do not use broad match with manual bidding or Enhanced CPC in 2026
Phrase match Target ROAS, Target CPA, or Maximise Conversions 30+ conversions per campaign per month recommended Works with Smart Bidding at lower data volumes than broad; also viable with manual bidding when volume is thin
Exact match Target ROAS, Target CPA, Maximise Conversions, or manual CPC No hard floor; can operate on fewer conversions due to tighter query control Manual bidding remains viable for exact match in low-volume or high-CPC categories where bid precision matters

Smart Bidding signals used with broad match

When broad match and Smart Bidding are paired, Google uses auction-time signals including user intent, query meaning, the campaign’s conversion history, target settings, and contextual factors to determine whether a given broad match query is likely to convert.[5][13] This is why conversion tracking quality is non-negotiable — if your conversion tracking is measuring the wrong action (e.g., page views instead of form submissions), Smart Bidding will optimise broad match toward irrelevant queries at scale.[10][15]

Value-based bidding preference

Where conversion value varies (e.g., different product margins, different lead quality tiers), value-based bidding with Target ROAS is preferable to Target CPA for broad match campaigns. Target CPA optimises for volume of conversions; Target ROAS optimises for the value of conversions — a critical distinction when broad match is generating a diverse mix of query types with different downstream value.[10][15]

Worked example

Smart Bidding strategy selection when launching broad match in an e-commerce account

  • Setup: An Adelaide homewares e-commerce account spending $15,000 a month operates three campaigns: brand exact ($3,000), non-brand exact/phrase ($10,000), and a new broad match discovery campaign ($2,000). The account records 120 conversions per month across all campaigns, with average order values ranging from $85 (promotional items) to $340 (furniture). Conversion tracking is via Google Ads tag with enhanced conversions enabled and revenue values passed dynamically.
  • Numbers: 120 total conversions per month clears the 50–100 conversion threshold for Smart Bidding.[2] The $2,000 broad match budget represents 13.3% of total spend, slightly above the 10% conservative cap[8] but within the 20%–30% growth-oriented range.[2] Average order value spread of $85–$340 (a 4:1 ratio) makes Target CPA inappropriate — a $150 CPA target would over-invest in $85 orders. Target ROAS at 350% (between broad match’s published 277%[12] and the account’s existing non-brand 390% ROAS) is set as the initial target.
  • Decision: Launch the broad match campaign with Target ROAS set at 350%, dynamic revenue values passed via conversion tag, Customer Match audience (8,500 existing customer emails) applied as an observation signal, and a 52-term shared negative list applied. Review ROAS and search term alignment after 14 days of data.
  • Why: Value-based Target ROAS is required when average order values span a 4:1 range, because Target CPA would treat an $85 conversion the same as a $340 conversion, degrading broad match’s return on the high-value portion of the catalogue.

9. Campaign Structure and Match Type Segmentation

How you structure campaigns around match types determines whether your performance data is actionable or obscured. In 2026, the best-practice model is to organise campaigns by intent tier — using different match types for different strategic purposes rather than mixing them arbitrarily within the same campaign.[3][4][5][17]

Recommended 2026 campaign architecture

Campaign tier Match types used Bidding strategy Primary purpose
Brand campaign Exact match (brand terms) Target Impression Share or Target CPA Protect branded visibility; maximum relevance control on owned terms
Non-brand exact/phrase campaign Exact + phrase match Target ROAS or Target CPA Capture proven high-intent queries; core performance engine
Broad match discovery campaign Broad match only Target ROAS or Maximise Conversions with CPA cap Find incremental queries not covered by exact/phrase; feed new exact match keywords

Why separation matters

Mixing exact, phrase, and broad match within the same ad group or campaign makes it impossible to diagnose which match type is driving performance or waste. Budget priorities are clearer when each tier has its own campaign budget. Bidding logic is cleaner because each Smart Bidding strategy trains on the data relevant to its purpose. Search term overlap between tiers is manageable through campaign-level negatives.[3][13]

Ad group structure within campaigns

Within each campaign, organise ad groups by tight intent themes rather than large keyword lists. In 2026, the strongest setups use fewer, more thematic ad groups — the old single-keyword ad group (SKAG) model is no longer recommended because it fragments data and makes Smart Bidding less effective.[3][13] A theme-based ad group of 5–10 tightly related keywords gives Smart Bidding enough intra-group signal while keeping ads, keywords, and landing pages aligned.[3][5][13]

Promoting winners from broad to exact

The discovery-to-control pipeline is a core operating rhythm: broad match surfaces new converting queries, weekly search term reviews identify winners, and those winners are added as exact match keywords in the non-brand exact/phrase campaign.[3][5][6] This keeps the exact match campaign perpetually refreshed with proven performers rather than relying solely on manually brainstormed keyword lists.

Worked example

Restructuring a mixed-match account into intent tiers

  • Setup: A Canberra IT managed services account spending $8,000 a month runs all keywords — brand, non-brand exact, phrase, and broad — within a single campaign with no match type separation. The account records 42 conversions per month, a $190 cost per conversion, and the campaign manager cannot identify whether brand traffic or broad match is inflating the conversion count. The search-term alignment score is 76%, below the 85% threshold.[2]
  • Numbers: At $8,000/month and 76% alignment, approximately ($8,000 × 0.24) = $1,920/month is attributable to misaligned queries. Separating brand traffic (estimated 20% of spend = $1,600) into its own campaign isolates it from non-brand data. Remaining $6,400 splits as: $4,480 (70%) to exact/phrase,[2] $1,920 (30%) to phrase expansion. Broad match is excluded entirely because 42 conversions per month is below the 50-conversion threshold.[2] Expected outcome: exact/phrase efficiency ratio of ~1.20 (between exact’s 1.48 and phrase’s 0.93[1]) on the non-brand budget, replacing the current blended 0.76 ratio.
  • Decision: Split into three campaigns effective 1 September 2026: Brand Exact ($1,600 budget, Target Impression Share 90%), Non-Brand Exact/Phrase ($4,480 budget, Target CPA $180), Broad Discovery ($0 budget — deferred until account reaches 50 conversions/month for two consecutive months). Port 52 negatives to a shared list applied to all three campaigns.
  • Why: The 85% alignment threshold[2] and the 50-conversion broad match floor[2] both indicate that structural separation and exact/phrase concentration are the correct response at this account size and current data volume.

10. Negative Keywords and Search Term Management

Negative keywords are the single most important control mechanism in a 2026 Google Ads account. Because all match types now expand by intent rather than literal text, negative keywords do the precision work that match types no longer guarantee.[3][5][6] Weak negative keyword management directly translates to wasted spend and degraded Smart Bidding signal quality — the system will optimise toward whatever queries it receives conversions from, including irrelevant ones if your conversion tracking is too broad.[4][7][12]

Negative keyword architecture

  • Shared account-level negative lists: Maintain a shared negative list of universally irrelevant themes (e.g., “free,” “DIY,” competitor brand names you do not want to appear against, unrelated product categories). Apply this list to all campaigns.[1][4][7]
  • Campaign-level negatives: Add campaign-specific negatives for intent clusters that are relevant to other campaigns but not this one (e.g., brand terms negated from non-brand campaigns).[1][4]
  • Ad group-level negatives: Use sparingly for very tight theme separation within a campaign.

Search term review cadence

Weekly search term reviews are the 2026 standard for accounts using broad or phrase match.[1][4][5] For exact-only accounts or accounts with very stable query patterns, a fortnightly review is acceptable. The review has two outputs: queries to negate (add to negative list), and queries to promote (add as exact or phrase match keywords in appropriate campaigns).[3][5][6]

Managing by intent cluster, not individual terms

Rather than evaluating each search term in isolation, group them into intent clusters: “buyer intent” (e.g., queries containing “buy,” “price,” “near me,” “quote”), “research intent” (e.g., “how to,” “best,” “review”), and “support intent” (e.g., “how do I fix,” “troubleshoot”). Decide at the cluster level whether to bid, block, or isolate into a separate campaign.[4][12][13] This approach scales better than term-by-term decisions and surfaces structural issues faster.

Negative match type selection

Negative keywords also have match types: negative broad, negative phrase, and negative exact. Negative exact match blocks only that precise query; negative phrase blocks any query containing that phrase; negative broad blocks queries deemed related to the negative term. For most cases, negative exact or negative phrase are preferred to avoid over-blocking legitimate queries.[7]

Worked example

Building a negative keyword system for a broad match discovery campaign

  • Setup: A Melbourne commercial cleaning company spending $7,200 a month launches a broad match discovery campaign on 12 October 2026 with a $1,200/month budget (16.7% of total spend). The campaign uses keyword “commercial cleaning Melbourne” in broad match with Target CPA set at $95. The account has 68 conversions per month — above the 50-conversion threshold.[2]
  • Numbers: In the first 7 days (budget ≈ $1,200 ÷ 30 × 7 = $280 spent), the search terms report shows 94 unique queries. Grouping into clusters: 51 queries (54%) are buyer-intent (legitimate), 23 queries (24%) are research-intent (borderline — “how to choose a cleaning company”), and 20 queries (21%) are irrelevant (residential cleaning, cleaning jobs, cleaning products). The 21% irrelevant share places the account below the 85% alignment threshold.[2] Cost attributable to irrelevant queries in week 1: $280 × 0.21 = $58.80. Annualised that is approximately $58.80 × 52 = $3,057.60 in wasted spend if uncorrected.
  • Decision: Add 20 irrelevant query terms as negative exact match keywords. Add “residential,” “jobs,” “career,” “products,” “DIY,” and “how to” as negative phrase match keywords to the shared account-level list. Schedule weekly Monday review recurring from 19 October 2026.
  • Why: The 85% alignment rule[2] requires immediate negative keyword action when misaligned traffic exceeds 15% of queries — waiting longer compounds wasted spend and degrades Smart Bidding’s conversion signal quality.

11. Brand and Non-Brand Controls

Separating brand from non-brand traffic is one of the most consequential structural decisions in a Google Ads account. Brand queries typically have higher CTRs, lower CPAs, and higher conversion rates than non-brand queries — mixing them in the same campaign inflates apparent non-brand performance and makes it impossible to measure the true cost of acquiring a new customer.[3][12][13]

Why match types alone are insufficient for brand control

Historically, advertisers used exact match keywords for brand terms to prevent broad or phrase match campaigns from triggering on branded queries. In 2026, Google has moved further toward recommending brand exclusions and brand inclusions as the primary mechanism for managing branded traffic, rather than relying on match type logic alone.[16][19] Brand exclusions prevent specified brand terms from triggering ads in a given campaign; brand inclusions restrict a campaign to only branded queries. These tools are available for Search campaigns and Performance Max.[16][19]

Brand keyword best practices

  • Use exact match for your primary brand keyword variants in a dedicated brand campaign — this provides the tightest bid and message control.[3][13]
  • Apply brand exclusions to non-brand campaigns to prevent branded queries from inflating non-brand conversion data.[16][19]
  • Consider bidding on competitor brand terms in a separate campaign, not mixed with your own brand or non-brand campaigns — competitor terms have different quality scores, CTRs, and conversion profiles.[3][12]
  • Set brand campaign bids to prioritise impression share (e.g., Target Impression Share at 90%+) rather than ROAS, because brand campaigns are primarily defensive.[3]

Preventing brand leakage into non-brand reporting

Brand leakage — branded queries triggering non-brand campaigns — is one of the most common causes of misleadingly good non-brand CPA figures. If your non-brand campaign shows a $45 CPA but 30% of its conversions are from branded searches, the true non-brand CPA may be over $60. Use campaign-level brand exclusions and weekly search term reviews to identify and eliminate this leakage continuously.[12][13]

Worked example

Isolating brand traffic to reveal true non-brand CPA

  • Setup: A Hobart travel agency spending $6,500 a month runs brand and non-brand keywords in a single campaign. The campaign reports 55 conversions per month at a $118 CPA. A search terms audit on 3 November 2026 reveals that 18 of the 55 conversions (32.7%) came from brand-name queries (e.g., “[agency name] holidays,” “[agency name] flights”).
  • Numbers: If brand conversions have a CPA of $40 (typical for high-intent, brand-aware users) and non-brand conversions have a higher CPA, then: total spend = 55 × $118 = $6,490. Brand spend = 18 × $40 = $720. Non-brand spend = $6,490 − $720 = $5,770. Non-brand conversions = 55 − 18 = 37. True non-brand CPA = $5,770 ÷ 37 = $155.94 — 32% higher than the blended $118 CPA. The account has been under-reporting its non-brand acquisition cost by $37.94 per conversion.
  • Decision: Split brand into a dedicated exact match campaign with a $720/month budget and Target Impression Share at 90%. Apply brand exclusions to the non-brand campaign effective 10 November 2026. Report non-brand CPA separately using the corrected $156 baseline.
  • Why: Blending brand and non-brand conversions masks the true cost of non-brand acquisition, leading to under-investment in non-brand campaigns that may actually be underperforming their targets.[3][12][13]

12. Common Mistakes to Avoid

The following mistakes are consistently observed in underperforming accounts in 2026. Most stem from applying outdated match type logic, misunderstanding how Smart Bidding interacts with match types, or treating keyword structure as a substitute for proper negative keyword management.[4][7][12]

  • Running broad match without Smart Bidding: Broad match without an automated bidding strategy has no quality filter. Every intent-adjacent query competes for budget without any conversion likelihood assessment.[18][6][10]
  • Treating exact match as a literal text lock: Exact match now includes close variants and same-intent queries.[7][1] Expecting zero query drift from exact match leads to under-investment in negative keyword management.
  • Launching broad match below the conversion volume threshold: Running broad match when an account generates fewer than 50 conversions per month means Smart Bidding is making decisions on insufficient data, typically resulting in wasted spend.[2]
  • Mixing brand and non-brand in the same campaign: This inflates apparent performance, obscures true non-brand CPA, and makes budget allocation decisions unreliable.[3][12][13]
  • No shared negative keyword list: Without a structured negative list applied at account level, the same irrelevant queries recur across campaigns and waste spend repeatedly.[1][4][7]
  • Duplicating the same keyword across all three match types in one ad group: This creates auction competition between your own match types, fragments conversion data, and obscures which match type is performing.[3][13]
  • Setting and forgetting broad match campaigns: Broad match requires active weekly search term review, especially in the first 4–6 weeks of a campaign. Irregular review allows irrelevant query themes to accumulate and degrade Smart Bidding’s signal quality.[4][7][11]
  • Using the wrong conversion action for Smart Bidding with broad match: If Smart Bidding is optimising toward a micro-conversion (e.g., page view, time on site) rather than a real business outcome (e.g., form submission, purchase), broad match will scale the wrong behaviour.[10][15]

Worked example

The cost of duplicate match type keywords in one ad group

  • Setup: A Newcastle childcare centre spending $2,800 a month runs [childcare Newcastle], “childcare Newcastle”, and childcare Newcastle (broad) as three separate keywords in the same ad group, a common legacy structure from pre-2021 accounts.
  • Numbers: The three keywords compete in the same auction for the same queries, fragmenting conversion data across three keywords. After 30 days: exact match keyword records 14 conversions, phrase records 6 conversions, broad records 4 conversions — totalling 24 conversions at a $116.67 CPA ($2,800 ÷ 24). The exact match efficiency ratio of 1.48[1] suggests that if all 24 conversions had been attributed to a single exact match keyword, the Smart Bidding model would have a cleaner, more confident signal. Additionally, broad match’s 46% impression share[1] is diluting the ad group’s quality score data by mixing high-quality exact-triggered impressions with lower-quality broad-triggered impressions in the same ad group.
  • Decision: Remove the phrase and broad match duplicates from this ad group. Move exact match to the non-brand exact campaign. Create a separate broad discovery campaign only if/when the account reaches 50 conversions per month — currently 24 conversions per month means broad match is not yet viable.[2]
  • Why: The 50-conversion threshold[2] and the efficiency ratio gap between exact (1.48) and broad (0.76)[1] both indicate that the account should consolidate on exact match until volume supports a proper broad discovery structure.

13. What Changed Recently (Last 30 Days)

As of August 2026, there is no new Google Ads announcement changing the core behaviour of keyword match types in the last 30 days. The post-2021 semantic matching model — exact matches on same meaning or intent, phrase matches on queries that include the meaning, broad matches on related queries — remains the current documented framework.[1][6][14]

It is important to note a limitation here: the available research does not include a verified Google product announcement from the last 30 days confirming a match type change. This section therefore reports the most recent documented guidance available rather than speculative changes.[1][6][14]

Brand controls: the most notable recent development

The most practically significant recent update is Google’s stronger emphasis on brand exclusions and brand inclusions as the correct mechanism for managing branded traffic in Search campaigns and Performance Max — rather than relying on match type selection alone.[16][19] This represents a shift in how Google frames brand control: it is now a campaign-setting decision, not a keyword match type decision.

Key implications:

  • Apply brand exclusions to broad and phrase match campaigns to prevent brand queries from triggering in those campaigns.[16][19]
  • Use brand inclusions in Performance Max to restrict brand query eligibility where needed.[16][19]
  • Do not rely solely on adding brand terms as negatives to non-brand campaigns — Google’s brand controls tooling provides a more robust and explicitly supported mechanism.[16][19]

Confirmed stable behaviours

  • Exact match continues to include close variants and same-intent queries — it is not reverting to literal matching.[1][6][18]
  • Phrase match continues to operate on the expanded meaning-based model introduced in 2021 — the strict word-order requirement has not been reinstated.[6][9]
  • Broad match continues to be positioned by Google as best used with Smart Bidding for scale, not as a standalone match type.[1][12][16]
  • Negative keywords are not affected by close variant expansion — a negative exact match keyword blocks that exact query and its close variants in most cases.[7]

Worked example

Migrating brand control from match types to brand exclusions in August 2026

  • Setup: A Sydney financial planning firm spending $11,000 a month has historically relied on adding its brand name as a negative phrase match keyword to its three non-brand campaigns to prevent brand queries from triggering. In August 2026 the account manager implements Google’s brand exclusions tooling as a more robust alternative.
  • Numbers: Before the change, the search terms report for the three non-brand campaigns shows 7 branded query instances per month slipping through the negative phrase match (estimated cost: 7 × $28 average CPC = $196/month in leaked brand spend). After applying brand exclusions at the campaign level on 5 August 2026, a 2-week monitoring period (5–18 August 2026) shows 0 branded queries in non-brand campaign search term reports, compared with 3–4 that appeared during the equivalent fortnight the prior month. The $196/month brand spend leak is eliminated. The brand campaign’s impression share simultaneously increases from 87% to 93% over the same period, as brand queries are now exclusively served by the dedicated brand campaign.
  • Decision: Retain brand exclusions as the primary mechanism. Keep brand name negative phrase match keywords as a secondary backup. Document the change in the account’s campaign settings log with effective date 5 August 2026.
  • Why: Google’s current guidance explicitly recommends brand exclusions/inclusions over match-type-based brand management,[16][19] and the 0 vs 3–4 query leak comparison in the 14-day window confirms the tooling closes gaps that negative keyword matching misses.
