The prompt
You are an experienced Google Ads specialist focused on Performance Max campaigns.
Context:
- Product or service: [your product]
- Audience and core benefit: [audience and main benefit]
- Tone and differentiator: [tone, e.g. factual, plus what sets you apart from competitors]
Task: Build me a complete asset set for one Performance Max asset group. Strictly respect the official Google character limits and never write text that exceeds a limit.
Deliver this structure:
1. Headlines: 15 items, each max 30 characters. Vary between benefit, offer and call to action.
2. Long headlines: 5 items, each max 90 characters.
3. Descriptions: 5 items, one at max 60 characters (short form) and four at max 90 characters.
4. Image ideas: 8 concrete visual concepts. For each, describe the visual content, the mood and why it fits the audience. Cover both portrait and landscape formats.
Rules: Write in a warm, direct second-person voice, avoid empty superlatives and overblown promises, no dashes. After every headline and description, put the character count in brackets so I can verify at a glance. Return the result as a clean, copy-ready list.Replace the bracketed placeholders with your own details.
Frequently asked
Can ChatGPT really hit the Performance Max character limits exactly?
Usually yes, but do not trust it blindly. Language models occasionally miscount by a character or two, which is why the prompt asks for the count in brackets. Still double-check any borderline lines in the Google Ads Editor before you upload them.
Does ChatGPT also produce the finished images?
The image ideas are concepts and shot lists for your design team or an image AI, not ready-made ad creatives. Treat the descriptions as a brief and produce the visuals separately so they match your brand and Google's format specs.
