Keyword Match Types
Also known as: Match Types, Keyword Matching Options
Match types control how closely a search query must relate to your keyword before your ad can show. Broad match reaches the widest range of related searches, phrase match requires the meaning of the phrase to be present, and exact match triggers only on the keyword's meaning and close variants, giving the tightest control.
Key Takeaways
- Match types control how closely a search query must relate to a keyword before an ad can show.
- Broad match reaches the widest range of related searches, trading precision for discovery.
- Phrase match requires the meaning of the phrase to be present in the query.
- Exact match triggers only on the keyword's meaning and close variants, giving the tightest control.
- Close variants mean even exact match can fire on synonyms and reworded queries.
How It Works
When someone searches, the platform compares the query against your keywords and their assigned match type to decide whether your ad is eligible. Broad match casts the widest net, phrase match narrows to queries carrying the phrase's meaning, and exact match restricts eligibility to the keyword's meaning plus close variants.
Because looser match types surface unpredictable queries, they should be paired with regular monitoring in the Search Terms Report so you can see exactly what triggered your ads. Queries you do not want become negative keywords, keeping spend focused on searches likely to convert.
Match type also shapes economics. Broad, untamed matching can raise your Cost Per Click by pulling in low-intent traffic, while tighter matching sends more relevant visitors to a strong page. Combined with a good Landing Page Experience, precise match types keep budget aimed at searches that actually turn into leads or sales.
Why It Matters
Match types are the primary lever for balancing reach against precision. The right mix controls which searches spend your budget, and pairing looser match types with strong negatives keeps discovery from turning into wasted clicks.
Example
A local dentist bids on "teeth whitening" as a phrase match keyword. Their ad shows for "teeth whitening near me" and "professional teeth whitening cost," which fit the intent. After reviewing search terms, they notice it also triggered for "teeth whitening at home kits," a poor fit, so they add "at home" and "kits" as negative keywords to stop wasting clicks on shoppers who want a product, not a procedure.
Common Mistake
Assuming exact match only shows for the exact words. Close variants mean it can trigger on synonyms and reworded queries, so even exact-match campaigns need a search terms review and negative keywords to stay clean.
Frequently Asked Questions
What are the three keyword match types?
Broad match, phrase match, and exact match. Broad reaches the widest set of related searches, phrase requires the phrase's meaning to be present, and exact restricts to the keyword's meaning and close variants for the tightest control.
Does exact match only show for the exact words?
No. Exact match includes close variants, so it can trigger on synonyms, reworded queries, and misspellings that share the keyword's meaning. That is why even exact-match campaigns need search term reviews and negative keywords.
Which match type should I start with?
Many advertisers start tighter with phrase or exact match to control spend, then test broad match paired with strong negative keywords and automated bidding once they have conversion data to guide the system.
