Google Ads Keyword Match Types in 2026: A Complete Guide
Google Ads has 3 keyword match types: broad, phrase and exact. How each works in 2026, what replaced broad match modifier and which fits your bidding.
In this article
Google Ads has three keyword match types for Search today: broad, phrase and exact. Broad match modifier (the +keyword syntax) stopped existing as a separate type in July 2021, when Google folded it into phrase match (Google Ads Help). And none of the three is literal anymore: even exact match triggers on searches that “have the same meaning or same intent” as your keyword.
Below: how each match type behaves in 2026 according to Google’s own documentation, why negative keywords follow different rules, where match types sit next to AI Max and Performance Max, and which combination to use based on your bid strategy and conversion volume.
Key takeaways
- Exact
[keyword]: same meaning or same intent. Phrase"keyword": searches that include the meaning of your keyword. Broadkeyword: related searches, even without your words.- Broad match modifier (
+keyword) can’t be created since July 2021. Legacy BMM keywords still serve, but behave as phrase match.- Google calls it “critical” to use Smart Bidding with broad match. On manual CPC, broad enters auctions without a bid tuned to each search.
- Negative keywords don’t expand to close variants: plurals, synonyms and misspellings have to be added by hand.
- When a search is identical to an exact match keyword, that keyword wins priority over phrase, broad, AI Max and Performance Max.
What are keyword match types in Google Ads?
A match type is the rule that decides which searches can trigger your ad from a given keyword. The broader it is, the more searches you reach and the less say you have over which ones. Google puts it this way: exact gives you “the most steering over who views your ad, but reaches fewer searches”, and phrase reaches more searches than exact but fewer than broad (Google Ads Help, keyword matching options).
| Match type | Syntax | What it matches | Example with the keyword trail running shoes |
|---|---|---|---|
| Broad | trail running shoes | Searches related to the keyword, which may not contain its direct meaning | ”best shoes for mountain running”, “trail socks” |
| Phrase | "trail running shoes" | Searches that include the meaning of the keyword | ”buy trail running shoes for women” |
| Exact | [trail running shoes] | Searches with the same meaning or same intent | ”trail running shoe”, “trail shoes for running” |
The example searches are illustrative. Google doesn’t publish a fixed list of what triggers what, and the only way to know for your account is the search terms report.
When I audit a Google Ads account, the match type mix is one of the first things I check. What interests me is what it reveals: broad running on manual CPC, the brand name in phrase competing with itself, or negatives nobody has touched in months.
Exact match: the most precise, but no longer literal
Exact match shows your ad on searches that have the same meaning or same intent as the keyword. It goes in square brackets: [keyword]. It gives you the most control and the least volume.
“Same meaning” covers a lot more than the keyword typed word for word. Google applies what it calls close variants to exact match: plurals, misspellings, abbreviations, reordered words that keep the meaning, implied words, synonyms and even searches with the same intent. In Google’s own example, the keyword [images royalty free] can show for “free copyright images” (Google Ads Help, close variants).
Where exact still earns its place:
- Your own brand. You want your brand to trigger your brand ads and nothing else. That’s my default recommendation, not a Google rule.
- High-value keywords you already know convert. Moving them to exact gives them priority and their own bid and ad.
- Small budgets or accounts with no history. When every click counts, exact limits spend on searches that aren’t your business.
It also has a structural advantage: if a search is identical to an eligible exact match keyword, that keyword is prioritized over any phrase or broad keyword and over Performance Max (Google Ads Help, prioritization). “Identical” includes spell-corrected searches, but not plurals or synonyms.
The limit is volume. With exact only, a small account can run short of the traffic Smart Bidding needs to learn. And because the ad shows for very specific searches, your ad copy has to answer exactly what the person typed.
Phrase match: the type that absorbed broad match modifier
Phrase match shows your ad on searches that include the meaning of your keyword, with words before or after. It goes in quotes: "keyword". Since 2021 it also does the job broad match modifier used to do.
Word order still matters when it changes the meaning. Google illustrates it with a moving service in one direction: the keyword won’t trigger if the search swaps origin and destination (Google Ads Help, phrase match and BMM changes). In another sector: "english to spanish translation" can trigger on “certified english to spanish translation service”, but shouldn’t trigger on “spanish to english translation”, because that’s a different job.
Does phrase still make sense in 2026? In Adalysis’s September 2025 study, phrase brought in 41% of conversions for lead gen campaigns on Maximize conversions, even though it has also expanded to loosely related searches; the full numbers are further down, in the section on bid strategies.
My read: phrase is still useful as a middle step. It’s where I put keywords I don’t want to release into broad yet, either because the account doesn’t have enough conversions or because word order changes the service. What I don’t do is keep the same keyword in phrase and broad in the same Smart Bidding campaign without checking what each one actually adds.
When does broad match work, and when does it burn budget?
Broad match shows your ad on searches related to your keyword, including searches that contain none of its words. There’s no special syntax. Google’s example: the keyword low carb diet plan can show for “carb free foods” or “mediterranean diet books” (Google Ads Help).
Google is blunt about the condition: “it’s critical to use Smart Bidding with broad match”, because that way, out of all the relevant searches you could reach, you’re “only competing in the right auctions, at the right bid” (Google Ads Help, guide to broad match). On manual CPC, broad enters auctions that nobody is pricing query by query.
The number Google uses to make its case: advertisers that change their phrase keywords to broad match see on average ~25% more conversions in Target CPA campaigns and ~12% more conversion value in Target ROAS campaigns while meeting targets (Google Ads Help). Two caveats Google itself includes: the data is from 2020, and additional budget may be needed to get that lift.
Broad works when three conditions are in place:
- Conversion-based bidding (Maximize conversions, Maximize conversion value, Target CPA or Target ROAS) with conversions measured correctly.
- Enough volume for bidding to have data. Google doesn’t publish a minimum conversion count for broad match. The closest reference is Target CPA: no history is needed to turn it on, but Google recommends evaluating performance over the last 30 days with at least 30 conversions (Google Ads Help, Target CPA). On Target CPA campaigns I use that figure as my line: below it, I don’t add broad outside a contained test. Target ROAS needs a different bar, which I cover in the Smart Bidding guide.
- Someone reviewing search terms and negatives. Weekly in the first month, at least monthly after that.
If one is missing, broad is working with information it doesn’t have. Before switching it on in a new campaign, check how to set up Smart Bidding.
There’s also a campaign-level broad match keywords setting that converts every phrase and exact keyword in the campaign to broad. It’s only available with conversion-based Smart Bidding, and Google prioritizes those keywords as if both a broad and an exact version were present (Google Ads Help).
Which keyword wins when several match the search?
All match types are eligible to match close variants by default (Google Ads Help). That means one search can match several keywords in your account at once. Google picks which one enters the auction in this order (Google Ads Help, prioritization):
- Exact match keywords identical to the search.
- Phrase and broad keywords (including AI Max) or Performance Max search themes identical to the search.
- If nothing is identical, an AI-based system picks the most relevant ad group or asset group by meaning and context.
When several keywords or search themes sit on the same step, Ad Rank decides. One practical exception: if the keyword sits in a budget-limited campaign, it won’t always be able to trigger an ad.
This answers a common question: you don’t need to duplicate the same keyword across all three match types “to cover everything”. Google states that broad match keywords can take traffic identical to them without repeating them in exact and phrase (Google Ads Help, how matching works). Duplicating makes sense when you want the exact version to have its own bid, ad or budget.
Negative keyword match types: different rules
Negative keywords also come in broad, phrase and exact, but they don’t behave like positive keywords. The biggest difference: negatives don’t expand to close variants. In Google’s example, if you exclude the broad match negative flowers, your ad won’t show for “red flowers” but can still show for “red flower” (Google Ads Help, negative keywords).
| Negative | Blocks the search when… | With the negative free course |
|---|---|---|
| Broad (default) | It contains all the negative’s words, in any order | Blocks “free english course” and “course free”. Doesn’t block “free courses” |
| Phrase | It contains the words in the same order, with others before or after | Blocks “free course online”. Doesn’t block “course free” |
| Exact | It is exactly the negative, with no extra words | Blocks only “free course” |
Three practical consequences:
- Add plurals, synonyms and common misspellings by hand. “free course”, “free courses”, “no cost course”.
- An exact negative is a scalpel. Use it to cut one specific search without losing the longer ones that contain it.
- Negatives are respected when AI Max is on, according to Google’s FAQ (Google Ads Help).

Retired match types: broad match modifier and the AdWords legacy
If you’re searching “AdWords match types” or “broad match modifier”, you’re looking for a system that no longer exists in that form. Here’s the verified timeline:
- June 2018: AdWords is renamed Google Ads (Google, June 27, 2018). Match types stayed the same at that point; the brand changed.
- February 2021: Google starts folding broad match modifier (BMM) behavior into phrase match (Google Ads Help).
- July 2021: phrase and BMM share the same behavior in all languages. New keywords can’t use the
+keywordnotation. Existing ones keep serving, but behave as phrase match (Google Ads Help).
What that means for an older account:
| Legacy match type | Syntax | What it is today |
|---|---|---|
| Broad | keyword | Still exists, with much more intent-based matching |
| Broad match modifier | +trail +shoes | Retired. Legacy keywords behave as phrase |
| Phrase | "keyword" | Still exists, expanded with BMM behavior |
| Exact | [keyword] | Still exists, with close variants of same meaning and intent |
If you inherit an account with + keywords still live, nothing breaks. But it’s worth converting them explicitly to phrase, or to broad if the campaign meets the conditions above, so the account is readable and there are no hidden duplicates.
AI Max for Search and Performance Max: where match types fit
AI Max for Search isn’t a fourth match type. It’s a layer you turn on at Search campaign level, and it includes search term matching, which uses broad match and keywordless technology to find additional queries (Google Ads Help, AI Max). Google announced it on May 6, 2025 (Google Ads & Commerce Blog).
What Google has documented about how it relates to your keywords:
- Priority doesn’t change. Per Google’s announcement, keywords and keywordless matches are prioritized “the same as it does today” in Search and Performance Max. In the priority order, AI Max sits on the same step as phrase and broad; identical exact match stays ahead.
- It needs conversion-based bidding. AI Max search term matching doesn’t work with manual CPC (AI Max FAQ).
- It shows up in reports. In the search terms report you can filter the “Match type” column for “AI Max”, and the keywords report has aggregate rows for expanded and landing page matches (Google Ads Help, AI Max reporting).
- It has its own brand controls: brand lists you include or exclude at campaign or ad group level, from the AI Max settings panel (Google Ads Help, AI Max reporting).
The official figure: advertisers that activate AI Max typically see 14% more conversions or conversion value at a similar CPA/ROAS, and 27% for campaigns still mostly using exact and phrase keywords (Google Ads & Commerce Blog and Google Ads Help, Google internal data, 2025, non-retail advertisers). That’s Google measuring its own product, so I treat it as an optimistic ceiling.
Performance Max works in a similar way: it doesn’t use match-typed keywords, but search themes and keywordless targeting, and it supports negative keywords and brand exclusions (Google Ads Help). If the search is identical to an exact match keyword in your Search campaign, that keyword wins.
If the search is identical to a PMax search theme and to a phrase or broad keyword (or an AI Max match), they sit on the same step and Ad Rank decides (AI Max FAQ). If nothing is identical, Google picks by relevance first, and Ad Rank only breaks ties between options with equal priority. I go deeper in the guide to Performance Max for ecommerce.
What the data says: match types by bid strategy
The most complete study I’ve found is Adalysis’s: 16,825 Search campaigns over three months, excluding brand campaigns and campaigns without conversion data, published on September 16, 2025. Its core finding is that the best match type depends on the bid strategy.
What the study found, strategy by strategy:
| Bid strategy | What happened | Adalysis recommendation |
|---|---|---|
| Target ROAS (ecommerce) | Exact: 27% of impressions, 40% of conversions. Broad: 46% of impressions, 35% of conversions. Phrase: 24% of conversions | Start with exact, add phrase, then broad if budget remains |
| Maximize conversion value (ecommerce) | Broad had a higher CPA than exact, but also a higher ROAS | Start with exact, add broad if budget isn’t spent |
| Maximize conversions (lead gen) | Phrase: 41% of conversions on 43% of impressions. Exact: 32% on 23% | Start with exact, add broad |
| Target CPA (lead gen) | Broad took over half of impressions; exact kept the lowest CPA | Start with exact, add phrase if budget isn’t spent |
One detail looks contradictory: in lead gen on Maximize conversions, phrase brought in the most conversions, yet Adalysis still recommends adding broad before phrase. Its argument: phrase has expanded to search terms the author wouldn’t consider related, yet “phrase doesn’t use the bid signals that broad match can.”
Two warnings when reading this. These are aggregate shares across many accounts; yours may behave differently. And ecommerce and lead gen campaigns aren’t comparable with each other. Still, the pattern holds: exact is the base in every strategy, and broad is the volume lever once exact can’t spend the budget.
Which match type should you use, and when?
This is the framework I apply, with the source for each condition. The thresholds are the ones Google publishes; where there’s no official figure, I don’t invent one.
| Your situation | Match types to use | Why |
|---|---|---|
| Manual CPC or Maximize clicks | Exact and phrase. No broad | Google calls Smart Bidding critical for broad, and AI Max doesn’t work on manual CPC |
| Target CPA with fewer than 30 conversions in 30 days | Exact as the base, phrase to cover variations | Google recommends evaluating Target CPA with at least 30 conversions over 30 days. Target ROAS needs a different volume bar |
| Smart Bidding with volume, and budget exact can’t spend | Exact + broad (or phrase first on Target ROAS/CPA) | The sequence Adalysis recommends per bid strategy |
| Your own brand | Exact, plus brand exclusions or controls in AI Max and PMax | My recommendation: don’t pay for brand traffic you can’t control |
| Campaign with AI Max on | Keep your highest-value exact keywords | Identical exact matches keep priority over AI Max and PMax |
And one routine that doesn’t depend on match type: review the search terms report, move what converts to exact and what isn’t your business to negatives. You adjust the match type structure from that data.

Frequently asked questions about Google Ads match types
What was broad match modifier, and does it still exist?
It was a match type marked with + before each word (+trail +shoes) that required those words to appear in the search. Google retired it in 2021: since July of that year you can’t create keywords with that notation, and legacy BMM keywords behave as phrase match.
What’s the difference between broad, phrase and exact match?
Exact [keyword] matches searches with the same meaning or intent. Phrase "keyword" matches searches that include the meaning of the keyword, with extra words. Broad matches related searches, even without your words. Going from exact to broad, you gain reach and lose control.
What happened to AdWords keyword match types?
AdWords became Google Ads in June 2018. Of the four match types from that era (broad, broad match modifier, phrase and exact), three remain. Broad match modifier merged into phrase in 2021, and all of them have become more flexible: today they’re based on meaning and intent, not literal matching.
Is exact match still exact?
Not literally. It includes close variants: plurals, misspellings, reordered words, synonyms and searches with the same intent. It’s still the match type with the most control, and when a search is identical to an exact keyword, that keyword gets priority over phrase, broad, AI Max and Performance Max.
Can I run broad match only?
Yes, and there’s even a campaign setting for it, but only with conversion-based Smart Bidding. Google calls Smart Bidding critical for broad match. If you use Target CPA, Google recommends evaluating it with at least 30 conversions over 30 days; below that volume, start with exact and phrase.
Do negative keywords block plurals and synonyms?
No. Negatives don’t expand to close variants, so “free course” doesn’t block “free courses” or “no cost course”. You have to add each variant by hand. Their match types also work differently: a broad negative blocks searches with all its words in any order, phrase requires the same order, and exact blocks only that search.
