Broad match is a keyword match type in search engine advertising that allows your ad to show when someone searches for a keyword that is close in meaning to the keyword you’ve targeted. When you use broad match, your ad can show any search terms that include the words in your keyword, in any order, and with other words before, after, or between them.
For example, if you target the keyword “running shoes,” your ad could show for searches such as “best running shoes,” “women’s running shoes,” or “running shoes for men.”
Broad match keywords is the most flexible and widely used match type in search engine advertising and is a good choice for advertisers who want to reach a large audience and are starting to build their campaigns. However, it can also result in your ad showing for irrelevant searches, leading to low-quality traffic and wasted ad spend.
To control which searches trigger your ad and ensure that it only shows for relevant searches, you can use more restrictive keyword matches types such as a phrase or exact match. These match types allow you to target specific combinations of keywords and phrases and are typically used by more experienced advertisers who want to achieve better campaign results.
