Why this prompt works
Varying caption length across variants is both an A/B testing strategy and an audience test — different segments engage with different depth. The 'genuinely different psychological approach' rule prevents the common failure of three captions that say the same thing three ways.
Tips for best results
- Save your best-performing captions in a swipe file and give them to the AI as examples — it will pattern-match your voice far more accurately than tone descriptions alone
- The caption that earns the most saves is usually educational: 'Save this for when you need [outcome]' in the CTA dramatically boosts saves
- Hashtag research tip: search your top 3 competitors' posts and note which mid-size hashtags (50k–500k posts) they use — these are the discovery sweet spots
- For product posts, name a specific outcome the customer will experience in the first line — not the product feature, but the feeling or result
- Test your first line by reading it out loud in 3 seconds: if it doesn't create a question in your mind, it won't in your audience's either
