Google Ads match types control how closely a search must relate to your keyword before your ad can enter the auction. There are three: broad match (related searches), phrase match (searches that include your keyword’s meaning) and exact match (searches with the same meaning or intent). All three now match on meaning rather than exact words.
That last point is why so many older guides mislead. Broad match modifier was retired in 2021, exact match hasn’t meant word-for-word for years, and in 2026 AI Max for Search adds matching that goes beyond your keyword list. Below you’ll find the current definitions, example searches for each type, how Smart Bidding and AI Max change things, and how to check what you actually matched.
Key takeaways
- Google Ads has three match types: broad, phrase and exact. Broad match modifier was retired in 2021 and now behaves like phrase match.
- All match types work on meaning, so exact match can show for plurals, misspellings and rewordings with the same intent.
- Google recommends broad match with Smart Bidding; without reliable conversion data, phrase and exact give small budgets more control.
- Since September 2026, Google has been upgrading campaigns that use the campaign-level broad match setting to AI Max.
- The search terms report shows what you actually matched; its match type column describes the search, not your keyword setting.
What are the Google Ads match types?
Match types are settings on each keyword that tell Google how much leeway to take when matching it to searches. You choose them with punctuation when you add a keyword:
| Match type | How to enter it | Your ad can show on searches that | Reach |
|---|---|---|---|
| Broad match | emergency plumber | relate to your keyword, even without its words | Widest |
| Phrase match | “emergency plumber” | include the meaning of your keyword, often with extra words | Middle |
| Exact match | [emergency plumber] | have the same meaning or intent as your keyword | Narrowest |
The types are nested. Phrase match covers every search that the same keyword in exact match would cover, and broad match covers everything phrase match does, plus related searches. Broad is the default, so a keyword typed without punctuation is broad match.
If a guide still lists four match types, it’s counting broad match modifier (+keyword). Google folded that behavior into phrase match in 2021: existing BMM keywords now act like phrase match, and you can’t create new ones. New to the platform?

How do broad, phrase and exact match work in 2026?
Each type matches on meaning, using Google’s understanding of language rather than a word-for-word comparison. What differs is how far from your keyword’s meaning a search may go.
Exact match in Google Ads
Your ad can show on searches with the same meaning or intent as the keyword. That includes close variants such as plurals, misspellings, abbreviations, stem words (floor and flooring) and rewordings that mean the same thing. A search that adds a new requirement falls outside it: [emergency plumber] shouldn’t match “emergency plumber for a boiler service”.
Phrase match
Your ad can show on searches that include your keyword’s meaning, including more specific searches. The meaning can be implied rather than spelled out. Word order counts when it changes the meaning: Google’s own example is a moving company keyword for New York to Boston that won’t show for a move from Boston to New York.
Broad match
Your ad can show on searches related to your keyword, even if they share none of its words. To judge what’s related, Google also uses other signals: the person’s recent searches, the content of your landing pages and assets, and the other keywords in the ad group. That’s powerful with good conversion data and expensive without it.
One tidy-up tip: reordered duplicates such as “red car” and “car red” add nothing. Google treats them as duplicates, and only the one with the higher Ad Rank enters the auction.
Broad match vs phrase match vs exact match: example searches
Here’s how one keyword could behave under each type for a plumbing company. It’s illustrative: real matching depends on Google’s systems and the context of each search, so confirm with your own search terms report.
| Search | Broad | Phrase | Exact |
|---|---|---|---|
| emergency plumber | Yes | Yes | Yes |
| emergency plumbers | Yes | Yes | Yes (close variant) |
| emergency plumbing service | Yes | Likely | Possibly (same meaning) |
| 24 hour emergency plumber near me | Yes | Yes | No (adds requirements) |
| boiler repair | Possibly (related service) | No | No |
| plumber salary | Possibly (a job seeker) | No | No |
| how to fix a leaking pipe | Possibly (a DIY researcher) | No | No |
The pattern is consistent. Exact match protects the budget, phrase match adds longer and more specific searches, and broad match finds searches you would never have listed, including some you don’t want. Your negative keywords decide how much of broad match’s extra reach you keep; our guide to negative keywords includes starter lists.
How does broad match work with Smart Bidding?
Google says it’s critical to pair broad match with Smart Bidding, because every search is priced individually using signals available at auction time, such as device, location, time of day and the actual query. Smart Bidding can bid low on a loosely related search and high on a strong one; a manual bid can’t make that distinction.
That only works if Smart Bidding knows what a good result looks like. Broad match makes sense when:
- conversion tracking records real leads or sales, with the right actions set as primary;
- the campaign already produces a steady flow of conversions each month;
- someone reviews the search terms report every week and adds negatives;
- the budget can absorb some exploratory spend while the system learns.
Your exact keywords keep priority. If a search is identical to an eligible exact match keyword, Google uses that keyword ahead of any broad or phrase keyword and ahead of Performance Max. Phrase and broad keywords identical to the search share priority with identical Performance Max search themes.
One setting to know: the campaign-level broad match setting switches every keyword in a Search campaign to broad match and requires conversion-based Smart Bidding. Google began automatically upgrading campaigns that use it to AI Max in September 2026.
How does AI Max change keyword matching?
AI Max for Search is an optional layer on Search campaigns that reaches beyond your keyword list. Its search term matching uses broad match and keywordless technology to find relevant searches from your keywords, ads and landing pages, alongside text customization and final URL expansion.
- AI Max is selected by default when you create a new Search campaign, so check the setting before you publish.
- Search term matching needs conversion-based Smart Bidding; Google says it won’t work with manual CPC bidding.
- You can switch search term matching off in individual ad groups while it stays on for the campaign.
- Negative keywords are still respected, and brand and location controls let you steer where it goes.
- In the search terms report, these matches show “AI Max” as the match type, with a source column saying whether each came from broad match expansion or keywordless matching.
Whether to turn it on is a separate decision, covered in our guide to AI Max for Search campaigns.
Which match type should you use?
Use the loosest match type that your conversion data and budget can support. For most small accounts, that means starting tight and loosening as evidence builds.
| Situation | Start with | Why |
|---|---|---|
| New account with little or no conversion data | Exact and phrase on your best keywords | Keeps spend on searches you chose while tracking proves itself |
| Small budget in a competitive market | Exact, plus a few phrase keywords | Broad match can spread a thin budget across marginal searches |
| Steady conversions and Smart Bidding in place | Broad match, tested against your current setup | Smart Bidding can price each search, and broad match finds demand you missed |
| Your brand name | Exact and phrase, in a separate campaign | Keeps high-intent brand traffic and its reporting apart from generic searches |
| Many services and little time for keyword upkeep | Broad match with Smart Bidding, or AI Max | Less keyword maintenance, as long as search terms get a weekly review |
Two numbers don’t change with match type. Keyword Planner reports average monthly searches for the exact form of a keyword whichever type you choose, and Quality Score is based on searches that exactly match your keyword. Choose match types for the traffic you want. How loose you can go also depends on budget; see how much to spend on Google Ads, or ask our PPC team for a second opinion on your setup.
How do you check what your keywords actually matched?
Use the search terms report. It lists the searches that triggered your ads, the keyword that matched each one and how each search performed.
- In Google Ads, open Campaigns, then Insights and reports, and select Search terms.
- Add the Keyword column (columns icon, then Attributes), because it isn’t shown by default.
- Sort by cost and read the biggest spenders first.
- Read the Match type column carefully. It describes how the search relates to your keyword, so a broad keyword shows “Exact match” when the search was identical to it, and close variants are labeled as such.
- Tick irrelevant searches and choose Add as negative keyword; Google adds them as negative exact match unless you change it.
- Add strong converting searches as their own exact match keywords, with an ad written for them.
The report never shows everything: searches used by too few people are left out for privacy. Search terms insights groups those into themes, which helps when a large share of spend seems unaccounted for.

Frequently asked questions
Do match types affect cost per click?
Match types don’t set the price of a click directly; the auction for each search does. Broader match types enter more auctions, which can include both cheaper and more expensive searches than your exact keywords. With Smart Bidding, Google sets a separate bid for every search, so broad match can bid low on weak searches. With manual bidding, one keyword bid applies to every search it matches.
Can I use the same keyword in more than one match type?
Yes, although Google says a broad match keyword already covers the searches of the same keyword in phrase and exact match. Advertisers still add an exact match copy to control the ad, bid or landing page for that precise search. When a search is identical to an eligible exact match keyword, Google prioritizes that exact keyword, so the copies don’t compete against each other.
Do match types apply to Performance Max?
Performance Max does not use keywords or match types. Instead, advertisers can add up to 50 search themes per asset group, which carry the same priority as phrase and broad match keywords in Search campaigns. Account-level and campaign-level negative keywords still apply to Performance Max on Search and Shopping inventory, and an identical exact match keyword in a Search campaign wins priority over Performance Max.
Which match type do negative keywords use by default?
Negative keywords typed without punctuation are negative broad match, which blocks searches containing all of the negative terms in any order. Negatives added from the search terms report default to negative exact match, which blocks only that exact search. Negative keywords never match close variants such as plurals, so add those versions separately whichever negative match type you use.
