What are keyword match types in Google Ads?

What do the three types do?

Google's help documentation describes them like this1:

  • Broad match. The loosest. Ads may show on searches that are related to your keyword.
  • Phrase match. In between. Ads may show on searches that include the meaning of your keyword.
  • Exact match. The tightest. Ads may show on searches that have the same meaning or the same intent as your keyword.

The same page says exact match gives the most steering over who sees your ad but reaches fewer searches1. Looser means the reverse.

Why does match type change what you pay for?

Match type decides which searches you buy. You pay for clicks on those searches, so it decides where the money goes.

A looser match type needs watching. Look at the actual searches that triggered your ads, then block the ones you do not want with negative keywords. Without that, a broad keyword can quietly spend on searches nobody meant to buy.

Automation sits on top of this. Smart Bidding sets bids, and Performance Max works across Google's inventory from one campaign. Match types are still where you tell Google what a keyword may mean.

Our view: match type is a spend decision, not a setting. The searches it buys should be read, not assumed.

Worked example

Easily confused with

  • Keyword match types vs Negative keywords

    They do the opposite job: they stop an ad being triggered by a word or phrase.

  • Keyword match types vs Keyword

    The word or phrase you choose. Match type is the rule for how closely a search must resemble it.

  • Keyword match types vs Search terms

    The words people actually typed. Your keyword is what you bid on. The search term is what they searched.

Which match type is best?

None, on its own. Exact match gives the most control. Broad match gives the most reach. The right mix depends on what the extra searches earn.

What is the default match type?

Broad match. Google's documentation says it is the default and uses no symbols1.
