Match Types Explained: Broad, Phrase, and Exact Match Keywords
By Bill Hartzer · Hartzer Consulting
Every keyword you add to a Google Ads campaign carries a match type, whether you set it deliberately or accept the default. Match type is the setting that determines how closely a person's actual search has to align with your keyword before your ad is eligible to show. Get it wrong in one direction and you waste spend on searches that were never going to convert; get it wrong in the other direction and you miss searches you should have been showing up for. Building a large keyword list — with a tool like the Word & Keyword List Combiner or the Three-List Combiner — is only half the job. Choosing the right match type for that list is the other half.
What match type actually controls
A common misconception is that match type is a formatting choice — add brackets, add quotes, or add neither. It's really a matching rule: it tells Google Ads how much latitude to give itself when deciding whether a real search query is "close enough" to your keyword to trigger your ad. Today, that decision is based on the meaning and intent behind a search, not a literal, word-for-word comparison — a meaningful shift from how match types worked when Google Ads first introduced them.
Broad match
Broad match is the widest net and the current default for new keywords. Your ad becomes eligible for searches Google Ads judges to be related to the meaning of your keyword, drawing on signals like the searcher's history, your landing page content, and the other keywords in your account. That reach is the appeal, and the risk: broad match can surface searches that only loosely relate to what you actually sell. It performs best when paired with strong automated bidding and an actively maintained negative keyword list (see our guide to building one), which does the work of narrowing the net back down.
Phrase match
Phrase match sits in the middle. Your ad is eligible for searches that include the meaning of your keyword, and that meaning can be implied rather than stated outright, with the search itself being a more specific variation of the keyword. It's a deliberately narrower net than broad match, and a deliberately looser one than exact, which is exactly why it's often the sensible starting point for a new keyword list: it gives Google Ads room to match real searches without the wide-open exposure of broad match.
Exact match
Exact match gives you the most control and the smallest reach of the three. Your ad becomes eligible only for searches Google Ads judges to have the same meaning or the same intent as your keyword — which still allows for close variants like plurals, misspellings, and reordered words that don't change what the searcher is actually looking for, but excludes searches that head in a different direction. Exact match is the right choice once you already know, from search term data, precisely which queries convert.
A quick note on history
If you've managed PPC accounts for a while, you'll remember when match types were closer to literal string-matching rules, and when "broad match modifier" existed as its own distinct option. That modifier was folded into phrase match, and all three match types have since moved toward the intent-based model described above. If you're working from an old mental model of how these behave, it's worth re-reading Google's current documentation before restructuring a large account — the underlying mechanics have changed even though the three names haven't.
Which match type should you use for a new list?
There's no single right answer, but a reasonable default for a freshly generated list is to start with phrase match while you gather search term data, then split out the proven performers into an exact match list once you know which specific queries convert. Broad match is worth testing deliberately, with a bidding strategy and budget that can tolerate its wider reach, rather than leaving it on by default simply because it's what Google Ads pre-selects.
Building match-type-formatted lists with Combine Words
The Word & Keyword List Combiner and Three-List Combiner both include an output-format option that maps directly onto these three match types: standard output for broad match, keywords enclosed in quotes for phrase match, and keywords enclosed in brackets for exact match. Combine your lists once, then generate the same set of combinations in whichever match type your campaign structure calls for — including a negative-keyword prefix in the same pass, if you're building a negative list rather than a positive one.
