Quick answer: Keyword match types are the rules that determine which searches trigger your Google Ads. Three types exist: exact match (most controlled), phrase match (medium control), and broad match (least control). Choosing match types correctly is one of the highest-leverage settings in any account: get them wrong and you waste budget on irrelevant searches.
What Are Keyword Match Types?
Keyword match types in Google Ads control how broadly or narrowly your keyword matches the searches that trigger your ad. Getting match types right is one of the most fundamental skills in PPC, the difference between wasting budget on irrelevant clicks and reaching exactly the right people.
The Three Main Match Types
- Broad Match: Your ad can show for searches related to your keyword, including synonyms and related topics. The widest net, useful for discovery but requires strong negative keyword management to avoid waste.
- Phrase Match (using “quotes”): Your ad shows for searches that include the meaning of your keyword. More controlled than Broad, but still allows some variation around the core phrase.
- Exact Match (using [brackets]): Your ad shows only for searches that match your keyword or close variants. The tightest control, lowest volume, typically highest relevance.
Broad Match Modified (Deprecated)
Google retired BMM in 2021. Phrase Match now covers much of the territory BMM used to occupy.
How to Use Match Types Strategically
- Use Exact Match for high-intent, high-value keywords where every click matters
- Use Phrase Match to capture variations while limiting waste
- Use Broad Match cautiously with robust negative keyword lists
- Review your Search Term Report regularly to see what broad and phrase match keywords are actually triggering
Keyword match type strategy is a core part of every campaign we build at BrisTechTonic PPC.
The Three Match Types
- Exact match [keyword]: shows for searches with the same meaning as your keyword. Modern exact match includes plurals, synonyms, and same-meaning rephrasings, so it’s broader than its old definition.
- Phrase match "keyword": shows for searches that include the meaning of your phrase. Wider than exact, narrower than broad.
- Broad match keyword: shows for searches related to your keyword’s general meaning. Widest reach; requires Smart Bidding to work well.
How to Choose
- Use exact match for highest-intent keywords where you want tight control.
- Use phrase match for broader reach with reasonable safeguards.
- Use broad match only with Smart Bidding and aggressive negative keyword discipline.
Most modern accounts mix all three rather than picking one.
Negative Keywords
Like positive match types, negatives have match types too: negative exact, negative phrase, negative broad. Use phrase match negatives by default; they catch genuine variations without being too aggressive.
Frequently Asked Questions
Has Google removed exact match?
No. Exact match still exists, just with broader interpretation than it had a decade ago. "Same meaning" rather than "same words" is the modern definition. Square brackets [keyword] still trigger exact match.
What happened to broad match modifier?
Google deprecated broad match modifier in 2021 and folded its functionality into phrase match. Phrase match is now slightly broader than it was, covering most of what broad match modifier used to.
Should I use broad match keywords?
Only when paired with Smart Bidding (Maximise Conversions, Target CPA, Target ROAS). Broad match without Smart Bidding wastes budget on irrelevant searches. With Smart Bidding, broad match can outperform tighter match types because the algorithm has more variation to work with.
How often should I review match types?
Weekly during the first month of any new campaign. Fortnightly thereafter. Monthly for stable accounts. The Search Terms report reveals whether match types are interpreting too broadly or too narrowly.
