Keyword Match Types Explained

A keyword in Google Ads is not the search people type. It is an instruction about which searches you are willing to pay for. The match type sets how loose that instruction is, and it is the single setting that most decides how much of your budget goes to the wrong people.

The three match types at a glance

None of the three match only the literal words any more. Since 2021, even exact match covers close variants: misspellings, plurals, reordered words and searches Google judges to mean the same thing. That is why reading the search terms report matters at every match type.

Broad match

Broad match lets Google show your ad for any search it considers related. For the keyword emergency plumber, that can include burst pipe help, 24 hour plumbing, and also plumber salary or how to become a plumber.

Broad match works well when three things are true: conversion tracking is accurate, you use Smart Bidding (so each auction is priced on the chance of a conversion), and the account has enough conversions for the algorithm to learn from. Without those, broad match mostly finds new ways to spend money.

Phrase match

Phrase match shows your ad when the search contains the meaning of your phrase. The keyword "water heater repair" will match water heater repair near me and same day water heater repair, and usually fix my water heater, but not water heater installation.

For most service businesses, phrase match is the working middle ground: it catches the many ways people describe the same job, without wandering into unrelated topics.

Exact match

Exact match gives the most control and the least volume. Use it for your highest-value searches, where you want a specific ad, a specific landing page and a bid you set deliberately. [emergency plumber near me] is a classic exact match keyword: high intent, high value, and worth isolating.

Because exact match now includes close variants, check the search terms report for it too. You will occasionally find a "same meaning" match that is not the same at all.

Which match type should you use?

Match types and negative keywords

Every match type needs negative keywords, and broad needs them most. Negatives have their own match types that work differently from normal keywords: they do not include close variants, so -job will not block jobs. The negative keywords guide covers this in detail, with starter lists.

Common mistakes

• The same keyword in several match types in one ad group, then wondering which one triggered. Group by intent instead, and let the search terms report tell you.
• Broad match on Manual CPC. Broad match is designed to work with Smart Bidding. On manual bids it buys a lot of loosely related traffic at the same price as your best searches.
• Never checking exact match. Close variants mean exact match can drift too.
• Judging too early. Give a match type change two to four weeks of data before deciding.
