What Are The Different Keyword Match Types In Google Ads?

Keyword match types tell Google how far a search can stray from the keyword you typed and still trigger your ad. There are still three, which are exact, phrase, and broad. None of them means “only this string of characters, and nothing else.” Close variants, including word order and implied meaning, have been part of matching for years. The job in 2026 is to know which type you are using and to read the queries it buys.

The three types, in plain terms

• Exact match is the tightest. The search should mean the same thing as the keyword. It will still match close variants. It will not stay inside a trivia-level spelling.
• Phrase match is the middle. The meaning of your keyword should be part of the search. Extra words can appear around it. It is the right home for many service accounts that are not ready to police broad match every day.
• Broad match is the widest. Google uses the keyword, the ads, the landing page, and the user’s recent searches to decide relevance. It finds queries you did not write down. It also finds jobs you do not do, unless negatives and conversion data push back.

Why broad match is the default conversation

Smart Bidding and AI Max are built to work with broad match. Search term matching inside AI Max uses broad match and keywordless signals. If your conversion tracking is solid and the ad group has one offer, broad match can be the reach layer. If tracking is a pageview, broad match will find more pageviews. That is not growth.

Campaigns that already used campaign-level broad match were pulled into AI Max in September 2026. If you thought you were “only” using broad match, check whether the other AI Max switches came with it.

Negatives are a match type too

Negative exact, phrase, and broad still limit what you refuse to buy. Add negatives for DIY, jobs, free, the services you retired, and the cities outside your area. Review search terms before you add a pile of negatives you copied from a 2019 list. A negative that blocks your actual service is worse than a loose match type.

How to pick one

On a new account with thin conversion history, start tighter, usually with phrase match on the core jobs, and add exact match on the few terms that already convert. Move a proven ad group toward broad match once you trust the conversion action and you have time to read queries. Do not run the same keyword in all three match types across duplicate ad groups. You will bid against yourself and learn nothing.

Match types are a control on waste, not a creative strategy. Pick the width you can supervise, and look at the search terms before you believe the dashboard.
