Google Ads Keyword Match Types: Broad, Phrase, Exact

When you add a keyword to Google Ads, you are not telling Google "only show my ad for this exact string of words." You are telling it how flexible to be about which searches count as a match. That flexibility is set by the keyword's match type, and it is one of the most consequential decisions in a campaign.

The reason it matters so much comes back to how you pay: every click costs money whether or not it converts. A match type that is too loose invites clicks from searches that have nothing to do with your business, and you pay for every one. A match type that is too tight can leave you invisible for perfectly good searches phrased slightly differently. Match types are how you tune that trade-off between reach and control.

There are three match types today: broad match, phrase match, and exact match. Google's older "modified broad match" has been folded into phrase match, so if you read older articles referencing it, that is why.

Broad match is the default and the most flexible. Your ad can show for searches that Google judges to be related to your keyword — including synonyms, related concepts, and searches that do not contain your keyword words at all. If you bid on lawn care as broad match, your ad might show for "landscaping services," "grass cutting," or "yard cleanup."

The upside is reach: broad match finds searches you would never think to add yourself. The honest downside is that it can also trigger on loosely related or outright irrelevant searches, and you pay for those clicks. Broad match has improved over the years — it now leans on Google's understanding of intent and works best paired with automated bidding — but it demands close monitoring and a solid negative keyword list. Turning it on and walking away is a reliable way to burn budget.

Phrase match is the middle ground. Your ad shows for searches that include the meaning of your keyword, in a way that keeps your intended sense intact. You wrap the keyword in quotation marks in the interface, like "emergency plumber".

With phrase match, a search for "24 hour emergency plumber near me" would qualify because it contains the meaning of your phrase. But "plumber apprenticeship" would not, because it changes the intent. Phrase match gives you noticeably more control than broad match while still catching the natural variations in how people actually type. For many local service businesses, phrase match is a sensible default — broad enough to capture real demand, tight enough to keep out obvious junk.

Exact match is the most controlled. You write the keyword in square brackets, like [roof repair portland maine], and your ad shows only for searches that mean the same thing as that keyword. It still allows close variants — misspellings, plurals, reordered words, and same-meaning phrasings — so it is "exact meaning," not "exact letters."

The trade-off is the mirror image of broad match: excellent control and typically higher relevance, but the narrowest reach. Exact match shines for your highest-value, highest-intent searches where you want tight command over your spend. The risk is missing valid searches phrased in ways you did not anticipate. Most well-run accounts use a mix: exact match on the proven money keywords, phrase or carefully managed broad match to discover new ones.

No match-type strategy is complete without negative keywords — terms you explicitly tell Google to never match. If you sell new HVAC systems and never do repairs, adding repair as a negative keyword stops you paying for repair searches. Common negatives include "free," "jobs," "cheap," "DIY," and "salary," depending on your business.

Negatives are how you make broader match types safe to run. They let you cast a wide net for discovery while systematically cutting out the searches that waste money. Reviewing your search terms report and adding negatives is ongoing hygiene, not a one-time setup task.
