How to use the Ad Copy Generator

Test smarter, not harder.

1

Describe the offer clearly

Include what it is, the main benefit and any differentiator. 'AI headshots in 5 minutes from 10 selfies' beats 'AI photo app'.
2

Pick platform and tone

Google headlines are tight and keyword-first; Facebook primary text allows more story; TikTok is hook-heavy. The copy adapts.
3

Split-test the variants

Run the short, long and headline variants against each other. Let the data pick the winner, then iterate from there.

Ad Copy Generator — FAQ

Does it follow platform character limits?

Yes. Headlines respect each network's limits (e.g. ~30-40 chars for Google headlines) and primary text variants are sized for the platform.

How many variants do I get?

Each run returns a headline plus two short text options and one longer option — enough to set up a proper A/B test.

Can I use it for Google Ads?

Yes — select Google Ads and the copy will be formatted for responsive search ads with headline and description limits.

Is the copy original enough for ad review?

Generated copy is original and typically passes review. Avoid unsupported claims or misleading promises, which are the main reasons ads get rejected.
