# Responsive Search Ads (RSA)

Responsive Search Ads are the standard Google Search ad format: you supply up to 15 headlines and 4 descriptions, and Google mixes and matches them in real time to find the best-performing combinations for each query. RSAs replaced the older Expanded Text Ads as the only standard search format.

## In depth

- Give Google genuinely different headlines, not 15 rewordings of the same idea. Diversity of angle is what lets the system find winning combinations.
- Pin sparingly: pinning a headline to a position guarantees placement but removes the testing freedom that makes RSAs work. Pin only compliance-required text.
- 'Ad strength' (Poor to Excellent) is a guideline, not a ranking factor; Excellent correlates with more assets and diversity but isn't a guarantee of performance.
- Watch the asset-level reporting to see which headlines earn 'Good' or 'Best' and prune the 'Low' ones.

## Common misconception

More headlines isn't automatically better if they're near-duplicates. RSAs reward distinct value propositions, not volume of slightly different phrasings.
