How do I A/B test captions?

Post different variants on different days or to different audience segments. Compare engagement metrics to find the winner.

What gets changed in each variant?

The AI varies hooks, emotional tone, CTA style, length, and structure while keeping the core message.

Start with 2-3 variants per post. More data points = more confidence in your results.
