CTR testing and thumbnail comparison guides
Creators search for practical ways to compare thumbnail variants, not abstract design theory. This cluster supports posts about A/B tests, face emotion, hook text, and mobile readability.
- Post intros can link directly to the maker with a test prompt.
- Examples should compare one variable at a time: face, text, prop, or color.
- Image alt text should describe the thumbnail lesson, not just the file name.
