A/B Test
Split test
In one sentenceComparing two versions (A and B) of an ad, page, email or post to see which performs better.
What it means
Change one thing (headline, image, CTA, subject line), show each version to a similar audience, and keep the winner. Over time, small wins compound.
How to use it
- Test one variable at a time and wait for enough data before deciding.
- Test big ideas first (offer, hook) before small details (button color).
How AI helps
AI can generate test variations quickly and help you read the results without fooling yourself with tiny sample sizes.
