An ad with the broad match keyword "car window repair" can show for searches such as:

• "replace car window"
• "automobile glass replacement"

These search terms are considered closely related or synonyms of the original keyword because they involve the same service of repairing or replacing car windows. However, irrelevant searches like "cars for sale" or "second-hand cars for sale" typically would not trigger the ad. Broad match keywords allow the ad to appear for variations, synonyms, or contextually related searches, which helps reach a wider audience and discover new relevant keyword opportunities while targeting the user's intent. Thus, ads with a broad match keyword "car window repair" can appear for related searches that imply car window repair or replacement services even if the exact words are not used in the search query.
