Google has just announced a major change for Responsive Search Ads (RSA).
Previously, RSA headlines and sitelinks were separate assets. Now, Google’s AI can dynamically turn unused RSA headlines into sitelinks, but only if it predicts better performance.
Key Details:
- AI-Driven Optimization: The system selects the best combination to maximize results.
- Performance-Based: Headlines are converted to sitelinks only if they’re expected to improve performance.
- Limit of Two: A maximum of two RSA headlines can be used as sitelinks.
- Unused Headlines Only: Headlines already appearing in the ad won’t be repurposed.
- Pinned Headlines Excluded: If a headline is pinned, it won’t be eligible for sitelink conversion.
- URL Consistency: The sitelink will use the same final URL as the ad.
- Global Rollout: This update applies to all languages worldwide.

This update means your best RSA headlines can now work harder, increasing engagement and driving results without additional effort.
