A few months ago, YouTube released A/B testing for thumbnails and titles. The feature was available only to selected creators, but it’s now rolled out to everyone. Creators can upload three titles and thumbnails for the videos, and whichever video performs better with that pair of thumbnails and titles, YouTube will make it the primary.
What is the YouTube A/B Testing Tool?
YouTube rolled out a feature to increase the click-through rate of the videos. Last year, the best version of the feature was launched, called test and compare. Now in 2025, the Thumbnail and Title A/B testing can be seen in YouTube Studio.
During the YouTube video upload process, creators can add three titles and a thumbnail. The video is recommended to viewers using each pair of thumbnails and titles. The video with the highest watch time metric will be selected as primary.
How does the YouTube A/B Testing Tool help Creators?
The creators can rely on the data they will get to know what type of title and thumbnail works for their audience. The working thumbnails and title will be thoroughly tested, and this will help the video stand out. Additionally, creators will receive insights to inform future videos and optimize them.
Conclusion
The YouTube A/B testing is now available to every creator. When uploading videos, creators can test three pairs of titles and thumbnails, and YouTube will automatically choose the pair with the highest watch time for the video. Lastly, the official update will help creators make informed decisions and increase click-through rate.
