Broad match is a keyword match type that search engines use to determine which search terms your ads are eligible to match against.

For example, when you add "hats" as a broad match keyword, you tell Google Ads to try to show your ad for searches containing that term or a similar one. Your ad might show for searches on "hat," "sun hats," "winter accessories", and "sombreros." Broad match keywords help you reach the widest audience.
