About A/B testing for Meta Ads
Meta Business Help Center · facebook.com Free Beginner
Meta's own help page for the A/B test feature in Ads Manager, which splits your audience so versions of an ad, audience or placement do not overlap.
- Run A/B tests from Ads Manager rather than comparing two ads by hand.
- Change one variable per test.
- Let the test finish before you scale the winner.
