Match types decide which searches your Google Ads keywords are allowed to show for. Pick them well and your budget goes to people looking for what you sell. Pick them badly and you pay for clicks from people who wanted something else. This guide explains broad, phrase and exact match in plain language, how negatives work, and how to choose for your own account.

Key Takeaways

  • Google Ads has three keyword match types: broad, phrase and exact. Broad is the default for every new keyword (Google Ads Help).
  • Exact and phrase match are now based on meaning, not just the exact words, so they reach more searches than their names suggest.
  • Broader match types capture everything the narrower ones do, plus more searches.
  • Negative keywords do not expand to close variants, so you must add plurals and synonyms yourself.
  • Broad match works best with Smart Bidding and good conversion tracking; without them it can spend quickly on loose searches.

What Is a Match Type?

Short answer: A match type is a setting on each keyword that controls how closely a person's search has to match that keyword before your ad can enter the auction.

When you add the keyword emergency plumber to a campaign, you are not buying that exact phrase. You are telling Google which searches you want to be considered for. The match type sets how strict or loose Google should be. You set it with simple punctuation around the keyword.

Broad match

Written as plain text: emergency plumber. Can show on searches related to your keyword, even ones that do not contain its words.

Phrase match

Written in quotes: "emergency plumber". Shows on searches that include the meaning of your keyword, often with extra words around it.

Exact match

Written in brackets: [emergency plumber]. Shows on searches with the same meaning or intent as the keyword.

The Three Match Types in Practice

Exact match

Exact match gives you the most control. Google says ads may show on searches that have the same meaning or same intent as the keyword (Google Ads Help). So [emergency plumber] can still match "plumber emergency" or "emergency plumbers", because the intent is the same. It will not match "plumber salary", because that person wants a job, not a plumber.

Phrase match

Phrase match sits in the middle. Searches can be a more specific version of your keyword, so "emergency plumber" could show for "24 hour emergency plumber near me". Since 2021 phrase match has also absorbed the old broad match modifier, which Google retired as a separate option; word order still matters where changing it would change the meaning (Google Ads Help).

Broad match

Broad match reaches furthest. Google can show your ad on related searches and may use extra signals such as the person's recent searches, your landing page and the other keywords in the ad group. Google's own help page says it is critical to use Smart Bidding with broad match (Google Ads Help), because the bidding system needs conversion data to tell good searches from poor ones.

Think of It as Nested Circles

Exact match is the smallest circle. Phrase match contains all of it plus more. Broad match contains phrase and exact plus related searches. Google describes it the same way: broader match types capture all the queries of narrower ones, plus more.

Which Keyword Wins When Several Match?

Most accounts have several keywords that could match the same search. Google's rules help here. If a search is identical to one of your exact match keywords, that keyword is preferred over phrase or broad keywords. If several ad groups are equally relevant, Google uses its own relevance check and then Ad Rank to choose (Google Ads Help). In practice, this means a well-built exact match keyword is a reliable way to make sure a specific search lands in the ad group and on the landing page you chose.

Negative Match Types Work Differently

Negative keywords stop your ads from showing on searches you do not want. They also come in broad, phrase and exact versions, but with one important difference: negatives do not match close variants or other expansions (Google Ads Help).

  • Negative broad blocks searches that contain all of your negative words, in any order.
  • Negative phrase blocks searches that contain the words in the same order.
  • Negative exact blocks only that exact search, with no extra words.

So a negative for jobs will not block job. If you want both gone, add both. This is one of the most common reasons wasted spend survives a negative keyword clean-up. Our Quality Score and wasted spend statistics show how much budget can leak this way.

Where AI Max Fits In

AI Max for Search campaigns is an optional layer you switch on inside an existing Search campaign. It turns on search term matching, which uses broad match and keywordless technology to reach searches beyond your keyword list. Matches it finds appear in the search terms report with "AI Max" as their match type (Google Ads Help). If you enable it, review that report closely for the first few weeks, just as you would with a new broad match keyword.

How to Choose Match Types for Your Account

STEP 01

Check your tracking first

If conversions are not tracked reliably, start with exact and phrase match. Broad match and Smart Bidding need accurate conversion data.

STEP 02

Start with proven searches

Put the searches you know convert, such as your service plus your city, into exact match so they get their own bids.

STEP 03

Add phrase for reach

Use phrase match to catch longer versions of those searches without opening the door to everything related.

STEP 04

Test broad on a budget

Once conversions are flowing, test broad match in a separate ad group or campaign with a set budget and compare cost per conversion.

STEP 05

Read the search terms report

Every week, look at which searches triggered your ads and add negatives for anything irrelevant, including plurals and synonyms.

STEP 06

Promote the winners

When a search from phrase or broad keeps converting, add it as an exact match keyword so you control its bid directly.

Common Match Type Mistakes

Leaving everything on the default

New keywords are broad match unless you add quotes or brackets. Many small accounts run on broad match without realising it.

Broad match with manual bidding

Broad match without Smart Bidding and conversion data has little to guide it, so it can spend on loosely related searches.

Assuming negatives cover variants

They do not. Add singular and plural forms and common synonyms as separate negatives.

Never opening the search terms report

Match types are only half the job. The report shows what you actually paid for, and it is where you find both waste and new keywords.

If your leads cost more than they should, loose matching is often one of the causes. We cover the others in why Google Ads cost per lead is so high.
