Google Ads' three settings for how closely a search must fit a keyword: broad, phrase and exact, each also reaching close variants.
A keyword in Google Ads isn't a search. Its match type decides which searches it can show an ad on.
- Broad match, the default, written as the plain keyword: searches related to it, including ones that don't contain its words.
- Phrase match, written in quotes,
"discount code": searches that include the keyword's meaning, with words before or after. - Exact match, written in square brackets,
[yourbrand]: searches with the same meaning or intent.
All three reach close variants. Phrase match absorbed the old broad match modifier in 2021, and word order in phrase match now counts only when it changes the meaning.
This is why a programme's terms should say “bid on or appear on”. A publisher's broad or phrase keyword can show its ad on “yourbrand discount code” without your name ever being typed into its account. The search terms report shows which searches each keyword actually matched, and negative keywords use the same three types with stricter rules.
