The prompt
You are a senior performance marketing copywriter for Google Ads. Write a responsive search ad (RSA) for the following campaign.
Context:
- Product/service: [your product]
- Target keyword and search intent: [your keyword]
- Audience and key benefit (USP): [your audience and USP]
- Call to action / landing page goal: [your CTA]
Task:
Create 15 headlines and 4 descriptions for this RSA.
Rules:
- Headlines: maximum 30 characters including spaces, count each one and show the count in brackets after every headline.
- Descriptions: maximum 90 characters including spaces, also show the character count in brackets.
- Include the target keyword literally or slightly varied in at least 3 headlines.
- Cover different angles: benefit, USP, trust/proof, offer, clear CTA.
- Speak to the search intent directly, no filler, no superlative spam.
- Write natural English, no em dashes or en dashes.
- Avoid repetition so Google can freely combine the assets.
Output format:
1. Numbered list of the 15 headlines with character counts.
2. Numbered list of the 4 descriptions with character counts.
3. A short note on which 3 headlines you would pin and why.Replace the bracketed placeholders with your own details.
Frequently asked
Does ChatGPT reliably stay within Google's character limits?
Usually, but not guaranteed. ChatGPT does not always count characters exactly, which is why the prompt asks it to print the count after each line. Double-check the borderline headlines (near 30 characters) in the Google Ads editor before you go live, since that shows the real limit.
Why 15 headlines and 4 descriptions?
That is the full allowance Google permits per RSA. The more useful assets you provide, the more combinations the algorithm can test. For very different ad groups, just adjust the keyword and USP in the prompt and generate a separate set for each group.
