Tested on: GPT-4oClaude 4

The Prompt

Act as a Google Ads specialist with 8+ years managing search campaigns for B2B and B2C clients.
Write a complete Responsive Search Ad (RSA) for:
Product/service: {product}
Target keyword: {primary keyword}
Landing page URL: {URL}
Unique selling points: {list 3-5 USPs}
Negative constraints (what NOT to say): {e.g. no pricing, no competitor mentions}

Output:
1. 15 headlines (each under 30 characters, labeled H1-H15)
   - 3 must include the target keyword
   - 3 must state a specific benefit (not a feature)
   - 3 must include a number or stat
   - 3 must have a CTA verb (Get, Start, Try, Book, etc.)
   - 3 can be brand/credibility signals
2. 4 descriptions (each under 90 characters)
   - 1 focused on primary benefit
   - 1 focused on social proof
   - 1 addressing a common objection
   - 1 with urgency or scarcity (if applicable)
3. 3 sitelink extensions (title + 2-line description each)
4. 5 callout extensions (under 25 characters each)

Constraints:
- Headlines must read naturally when Google combines them in pairs
- No exclamation marks in headlines (Google policy)
- All copy must be truthful — no "best in the world" unless provable

Variables to fill in

  • {product} What you're advertising
  • {primary keyword} The main search term you're targeting
  • {USPs} 3-5 specific advantages over alternatives
  • {negative constraints} Things to avoid in the copy

How to use this prompt

RSAs reward variety, not repetition

Google’s machine learning selects the best headline+description combination for each auction. If all 15 headlines say essentially the same thing, Google’s algorithm has no meaningful variation to test — and your Quality Score suffers. The prompt’s headline breakdown (keyword, benefit, stat, CTA, brand) forces genuine variety.

The 30-character headline constraint is strict

Google will reject headlines over 30 characters. The prompt enforces this, but always double-check your output — especially headlines with numbers or brand names that can run long. A rejected headline silently drops from rotation without warning.

Extensions are free real estate

Sitelinks, callouts, and structured snippets add 30-40% more screen space to your ad at no extra cost. Most advertisers write 2-3 mediocre extensions. This prompt generates a full set — use all of them.
