Description:
Ads typically comprise an image, body copy, a headline, and a call-to-action (CTA). Within each element, there are additional variations, e.g. photo vs. graphic, descriptive vs. persuasive, etc. To optimize your ads, A/B test each element with the others remaining constant, then combine the winners of all tests. You can also use Facebook ads to build multivariate tests to assess which combination performs best.
