Google Ads Match Types: Broad, Phrase and Exact Explained

What are Google Ads match types?

Google Ads match types are keyword settings that decide how closely a search must relate to your keyword before your ad can enter the auction. There are three: broad match, phrase match and exact match. You choose one with symbols around the keyword, and broad match is the default when you type no symbols.

A keyword is not the search itself. You bid on the keyword "water heater repair", and people type searches such as "emergency water heater repair in Mesa". The match type decides which of those searches your keyword may cover, and every search it covers is a click you may pay for.

The three overlap. Google says broader match types capture every search the narrower ones reach, plus more: phrase match covers all the searches exact match covers, and broad match covers all the searches of phrase and exact (About keyword matching options). So the same keyword in all three match types inside one ad group adds very little reach.

Match types apply to keywords in Search campaigns. On the Display Network every keyword acts as broad match. Shopping campaigns use no keywords, and Performance Max search themes behave like phrase or broad match keywords.

Broad vs phrase vs exact match: which searches does each one match?

Exact match covers searches with the same meaning as your keyword. Phrase match adds searches that contain that meaning plus other words. Broad match adds related searches that may not contain your keyword at all. Google's own examples show the difference:

The next table applies the same rules to a home-service keyword. It is illustrative: Google decides every match at auction time, so your own search terms report has the final word.

The row that surprises most advertisers is "how to repair a water heater". It contains the meaning of the phrase keyword, so phrase match can show your ad to someone who plans to do the job alone. Negative keywords such as "how to" and "diy" close that gap, as our guide to negative keywords explains.

How do broad, phrase and exact match work?

Each match type trades reach for control. Exact match gives the most control, broad match the most reach, and phrase match sits between them.

Exact match: [keyword]

Exact match shows ads on searches with the same meaning or intent as your keyword, and Google says it gives you "the most steering" over who sees your ad. It is not literal, as the close variants section below shows. Use it for searches you know convert, for brand terms, and for any search you want routed to one ad group and landing page.

Phrase match: "keyword"

Phrase match shows ads on searches that include the meaning of your keyword, with words before, after or around it. Word order still counts when it changes the meaning. In Google's example, the phrase keyword "moving services NYC to Boston" covers "affordable moving services NYC to Boston" and "NYC corporate moving services to Boston", but not a search from someone moving from Boston to New York City. For most small and mid-size accounts, phrase match is the safest default for non-brand keywords.

Broad match: keyword

Broad match shows ads on searches related to your keyword, including searches that lack its direct meaning. To judge what is related, Google also reads three signals: the person's recent search activity, the content of your landing pages and assets, and the other keywords in the ad group. Every keyword typed without symbols is broad match.

Changing a keyword's match type does not change its Quality Score. Google calculates Quality Score from searches that exactly match the keyword, as our Google Ads Quality Score guide explains.

What are close variants, and what does Google treat as the same meaning?

Close variants are searches that are similar to your keyword but not identical, such as misspellings, plurals, reordered words, synonyms and searches with the same intent. All three match types match close variants by default, and Google says there is no way to opt out (Keyword close variants).

The first row works in every language. The other five work in 27 languages, including English and Spanish.

Two practical points follow. First, the search terms report labels these matches. When the search "purple flowrs" triggers the keyword [purple flowers], the Match type column reads "Exact match (close variant)". Second, negative keywords do not stretch the same way. They cover casing and misspellings but not plurals, synonyms or other close variants, so the negative flowers blocks "red flowers" and not "red flower" (About negative keywords).

How does broad match work with Smart Bidding?

Broad match depends on Smart Bidding to decide which of its wider set of searches deserve a bid. Google calls Smart Bidding "critical" for broad match, because every search carries different signals and Smart Bidding sets a separate bid for each one at auction time.

Smart Bidding means the four conversion-based strategies: Maximize conversions, Maximize conversion value, Target CPA and Target ROAS. Since June 2026 Google labels the last two simply "Target CPA" and "Target ROAS"; the bidding works the same (About Smart Bidding). Our guide to Google Ads bidding strategies covers how to pick one.

Google's guide to broad match names two main benefits: broad match reaches relevant searches that phrase and exact match miss, and that wider set gives Smart Bidding more data to find conversions.

The catch is data. Smart Bidding learns from conversions, and Google recommends judging it over a period with at least 30 conversions, or 50 for Target ROAS. Target ROAS on a Search campaign also needs at least 15 conversions in the past 30 days before you can use it (About Target ROAS bidding). A campaign with five conversions a month gives broad match almost nothing to learn from. If conversion tracking counts the wrong action, such as page views or duplicate form fills, broad match learns to buy more of the wrong thing.

How does AI Max for Search change keyword matching?

AI Max for Search is a set of features you turn on inside a Search campaign, not a new campaign type. Its search term matching goes past your keywords: it uses broad match plus keywordless technology that reads your ads, assets and landing pages, so ads can show on searches that none of your keywords would match (How AI Max for Search campaigns works).

The dates that matter, from Google's April 15, 2026 AI Max announcement (updated June 11, 2026):

• April 2026: AI Max left beta.
• September 2026: Search campaigns using the campaign-level broad match setting were upgraded to AI Max automatically, with search term matching on. Campaigns using automatically created assets got search term matching and text customization. Google expected the upgrades to finish by the end of September.
• February 2027: the sunset and automatic upgrade of Dynamic Search Ads begins, after Google moved it from September 2026.

Broad match keyword

• Starts from a keyword you wrote
• Matches related searches
• Reported as Broad in search terms
• Works with any bid strategy (Google advises Smart Bidding)

AI Max search term matching

• Uses broad match plus keywordless matching from your ads and pages
• Can match searches no keyword covers
• Reported as AI Max, with a source column
• Off with Manual CPC

Five rules from Google's AI Max FAQ and help pages matter for match types:

• Ad group control. Search term matching is on by default when AI Max is on, and you can turn it off for each ad group.
• Bidding. Search term matching does not work with Manual CPC, and Google recommends a conversion or conversion value strategy.
• Negatives still apply. Google confirms that negative keywords are respected with AI Max on.
• Reporting. The search terms report shows "AI Max" as a match type, and a source column says whether a match came from broad match expansion or keywordless matching.
• Priority. AI Max matches share a tier with phrase and broad keywords in Google's priority order. Campaigns upgraded from the broad match setting lose the exact match priority that setting gave their keywords; Google suggests adding exact match copies to keep it (About the broad match keywords campaign setting).

Which keyword enters the auction when several of your keywords match?

Only one keyword from your account can trigger an ad for a given search, so your own keywords never bid against each other. Google picks that keyword in a fixed order, and an exact match keyword identical to the search comes first.

1. Identical exact match[skydiving license] wins the search "skydiving license" over phrase, broad and Performance Max

2. Identical phrase or broadIncludes AI Max and Performance Max search themes identical to the search

3. Most relevant ad groupGoogle's AI compares the search with each ad group's keywords and landing pages

4. Highest Ad RankBreaks any tie left after steps 1 to 3

Google's prioritization page uses skydiving to explain step 3. For the search "skydiving certifications near me", an ad group about skydiving licenses enters the auction ahead of one about advanced skydiving courses, because "license" is closer in meaning to "certifications". Ad groups built around one theme each make that choice easier for Google.

The order can break when the preferred keyword cannot serve. Google lists these exceptions:

• A keyword with "Low search volume" status, which is inactive
• Disapproved ads or landing pages in its ad group
• Location, audience or other targeting that excludes the person
• A campaign limited by budget
• Other ad formats: Shopping ads can still show beside your exact match ad
• Searches in AI Mode, AI Overviews, Lens or autocomplete, which Google does not treat as identical to any keyword

The practical use: add your best converting searches as exact match keywords in the ad group with the right ad and landing page. That routes them where you want, and it keeps a Search campaign ahead of Performance Max for those exact searches.

Which match type should you use? A strategy by budget and data

Pick match types by how many conversions a campaign produces. Below about 30 conversions a month, phrase and exact match keep spend on searches you chose. With steady, accurate conversions and Smart Bidding, broad match and AI Max have enough data to find more.

For example, a garage door company spends $1,500 a month at a $6 average CPC, which buys about 250 clicks. At a 6% conversion rate it gets about 15 conversions a month, half the 30 Google suggests for judging Smart Bidding, so it runs phrase and exact. An online store spending $9,000 a month at $1.50 per click buys about 6,000 clicks; at 2% that is about 120 orders a month, enough to test broad match with Target ROAS. Both examples are illustrative.

$1,500 a monthBudget at a $6 average CPC (illustrative)

250 clicks$1,500 ÷ $6

15 conversions250 × 6%: phrase and exact until this passes about 30

The thresholds are our working rules, built on Google's 30 and 50 conversion guidance. Three more rules we follow:

• Test broad match as a campaign experiment for at least four weeks, never by switching a whole campaign at once
• Keep brand keywords in their own campaign on exact and phrase match
• Fix conversion tracking before adding any broad match keyword

How do you use the search terms report to choose match types?

The search terms report lists the real searches that triggered your ads, and its Match type column shows how each one matched. Read the search term match type as well as the keyword's match type, because a broad keyword often matches searches in an exact or phrase way.

Google's own example: the broad match keyword purple flowers triggers on the search "purple flowers", and the report labels that search "Exact match" (About the search terms report). A keyword report credits that click to broad match anyway.

1. Open the report. Go to Campaigns, then Insights and reports, then Search terms.
2. Add the Keyword column. It is hidden by default. Click the columns icon, open Attributes and tick Keyword.
3. Pick 30 to 90 days and sort by cost. The costliest rows matter most.
4. Read the Match type column. You will see Exact, Phrase and Broad, each with a "(close variant)" label where it applies, and AI Max if that feature is on.
5. Segment the keyword view. On the Keywords page, click Segment and choose Search terms match type to see how much of each keyword's traffic came through each match type.
6. Act on what you find. Use the table below.

The report leaves out searches that only a few people typed, for privacy. Search terms insights groups those into themes, so check it too before you decide a broad keyword is clean.

How are negative keyword match types different?

Negative keywords use the same three symbols, but they block searches instead of matching them, and they do not expand to close variants. A negative broad match keyword blocks searches that contain all its words in any order, negative phrase blocks the words in that order, and negative exact blocks only that exact search.

They cover casing and misspellings but not plurals or synonyms, so add "job" and "jobs" separately. Our negative keywords guide covers starter lists, levels and the weekly review.

What happened to broad match modifier?

Broad match modifier (BMM) no longer exists as a separate match type. Google began folding its behavior into phrase match in February 2021, and since July 2021 you cannot create new keywords with the plus sign notation, such as +moving +services (About changes to phrase match and broad match modifier).

Old BMM keywords still run, and they behave exactly like phrase match. A keyword that had the plus sign on only some words now acts as full phrase match. If you edit the text of an old BMM keyword, Google converts it to quotes when you save. Any Google Ads guide that still tells you to add plus signs is out of date.

Which match type mistakes waste the most budget?

Four habits cause most of the match type waste we find, and each takes minutes to check:

• Keywords with no symbols by accident. A keyword pasted without quotes or brackets runs as broad match, often on Manual CPC or Maximize clicks.
• Judging broad match by the keyword report. Broad keywords pick up exact and phrase type searches, which flatters their results.
• Auto-applied broad match. The Add broad match keywords recommendation can be set to auto-apply and change match types without anyone approving it (About applying recommendations automatically).
• Missing the AI Max upgrade. Campaigns that used the broad match setting before September 2026 can now match searches none of their keywords contain.
