In responsive search ads, which components are typically tested to improve relevance?

• A. Headlines and descriptions
• B. Display URL and tracking template
• C. Campaign names
• D. Bidding strategy

Answer: (A)

In responsive search ads, the text that actually communicates with the user is tested to boost relevance. You provide multiple headlines and several descriptions, and the system automatically mixes and matches these assets to create different ad variants. This ongoing testing helps Google learn which combinations best match the user’s search intent, delivering the most relevant message for each query. The display URL and tracking template deal with where users land and how you measure results, not the ad copy itself. Campaign names are organizational, and bidding strategy affects cost and auction dynamics rather than the relevance of the message. So the elements actively tested to improve relevance are the headlines and descriptions.
