L042 – A/B testing titles and thumbnails (EN)

This lesson explains how to test titles and thumbnails without confusing results, using only one variable at a time.

Goal

By the end you will have:

• 1 clear test hypothesis
• 2 title or thumbnail versions
• a reading criterion (CTR, retention, time)

Quick example

Title A = "How to find your format".

Title B = "Your format in 3 moves".

Same video, same publication.

Next step

Create 2 variants and plan a 7-14 day test.
