1. What Are Keyword Match Types?

Keyword match types define how closely a user’s search query must match your chosen keyword for your ad to appear.

In simple words:

Match types control who sees your ads.

When you select a keyword, you’re not buying that keyword alone—you’re buying a range of search queries, and match types decide how wide or narrow that range is.

2. How Google Matches Search Queries to Keywords

Google Ads does not match keywords literally anymore.

Instead, Google uses:

• Search intent

• Semantic meaning

• Synonyms

• User behavior

• Context (device, location, past searches)

This means:

• A keyword does not need to contain the exact words

• Meaning matters more than wording

• Match types act as guidelines, not strict rules
