Exact, phrase, and broad match decide who sees your ad. Here’s when to use each — and the common mistakes that burn budget fast.
Why Match Types Matter
Match types are the single biggest lever in Google Ads after the keyword itself. They control how tightly Google matches your ad to a search. Get them wrong and you’ll pay for traffic that was never going to convert — or, just as bad, miss traffic that would have. Most new accounts waste 30–50% of spend in the first 60 days purely because match types weren’t set intentionally.
Exact Match
Exact match ([keyword]) is the tightest. It matches the search if the query has the same meaning and intent. ‘plumber near me’ will match ‘emergency plumber near me’ but not ‘plumbing career.’ Use exact match for your highest-intent, proven-converting keywords where CPA matters more than volume. Expect lower volume and higher quality — that’s the trade-off.
Phrase Match
Phrase match ("keyword") matches queries that include the meaning of your phrase, allowing variation before, after, or within. ‘emergency plumber’ matches ‘24 hour emergency plumber Toronto’ and ‘emergency plumbing service.’ Phrase match is the sweet spot for most accounts: wider reach than exact, but still tightly relevant. Start new campaigns with phrase — then promote high performers to exact and block irrelevant variants with negatives.
Broad Match
Broad match is the widest net. Google uses the keyword as an intent signal but can match synonyms, related terms, and contextually similar searches. ‘emergency plumber’ might match ‘who do I call for a burst pipe.’ Broad is powerful for discovery but dangerous without aggressive negative keyword management — Google will spend your budget on marginal relevance unless you teach it otherwise every day.
A Match Type Strategy That Works
Structure matters more than any single match type. A proven approach: use phrase match for your main ad groups to capture variation, pair with a broad match ad group on low-CPC theme keywords to find new queries, and funnel top performers to exact match once they prove out. Pull your search terms report daily for the first month and add 10–30 negatives per day. This ritual alone separates profitable accounts from unprofitable ones.
Common Mistakes
The biggest mistake is running broad match without daily negative management — the fastest way to burn $5K with nothing to show. The second is running only exact match — starves the account of discovery and volume. The third is assuming phrase match behaves like it did in 2020 (it doesn’t — Google relaxed matching significantly, so phrase today is closer to old broad match modified). Always verify match behaviour in your search terms report, not in the docs.
