Responsive Search Ads let you supply up to 15 headlines and 4 descriptions that Google assembles at auction time. Fill all 15 headlines with different jobs — keyword theme, benefit, differentiator, trust signal, call to action and offer. Pin deliberately: keyword and intent at position 1, unique selling point at position 2, trust signal and call to action at position 3. Ad Strength is a guideline, not a KPI. Run three RSAs per ad group, use descriptions to handle objections, match the ad copy to the landing page, and review the asset report every two weeks.
