What should you test when optimizing RSAs?

• A. Test a single headline only
• B. Test multiple variants of headlines and descriptions
• C. Do not test at all
• D. Increase budget only

Answer: (B)

Testing multiple variants of headlines and descriptions is essential when optimizing RSAs. RSAs mix and match up to 15 headlines and 4 descriptions, and Google's machine learning evaluates which combinations perform best across different queries and landing pages. Providing a variety of messaging options lets the system learn which headlines and descriptions resonate, improving click-through and conversions over time. If you test only a single headline, you limit learning and miss potentially higher-performing messages. Increasing budget doesn't identify the best ad copy; it affects reach, not which messages work best. Regularly pause or replace underperforming assets and add new variants to keep improving performance.
