- 3 must include the target keyword

3. 3 sitelink extensions (title + 2-line description each)
4. 5 callout extensions (under 25 characters each)

{primary keyword}The main search term you're targeting -
{USPs}3-5 specific advantages over alternatives -

How to use this prompt
- Run the prompt then paste all 15 headlines and 4 descriptions into your RSA
- Pin your strongest headlines to positions 1 and 2 to ensure they always show
- Use the sitelink extensions as-is or adapt them to your most important landing pages
- Add the callout extensions to the campaign level so they appear across all ad groups
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.
