FAQ
Frequently Asked Questions
What is a Responsive Search Ad (RSA)?
A Responsive Search Ad is Google Ads' primary search ad format. You provide up to 15 headlines (30 characters each) and 4 descriptions (90 characters each), and Google automatically tests different combinations to find the best-performing ad for each search. RSAs replaced Expanded Text Ads in 2022.
How does this RSA writer work?
Enter your target keyword, website URL, and a brief product description. Our AI generates 15 pinned headlines across 3 position groups (keyword variations, thematic, and variety) plus 4 descriptions — all within Google Ads character limits and optimised for SaaS businesses.
What is headline pinning in Google Ads?
Pinning forces a headline to only appear in a specific position (1, 2, or 3) in the ad. Position 1 headlines show first and should contain your keyword. Position 2 headlines typically focus on trust or benefits. Position 3 headlines add variety. Strategic pinning ensures your keyword always appears while letting Google optimise the rest.
How many headlines should an RSA have?
Google recommends providing all 15 headlines for maximum performance. Each headline must be 30 characters or fewer. This tool generates 15 headlines grouped by position, giving you a complete RSA ready to import into Google Ads.
What makes good RSA copy for SaaS?
Effective SaaS RSA copy leads with the target keyword in Position 1, builds trust or highlights benefits in Position 2, and adds variety (questions, pain points, urgency) in Position 3. Descriptions should expand on the value proposition within 90 characters. This tool applies these principles automatically.
