The process of picking that all-important thumbnail for your latest YouTube video might be getting a lot easier soon. YouTube says it’s conducting early testing of a feature it’s calling “Test & Compare,” which lets creators upload up to three thumbnails for a single video and let YouTube experiment behind the scenes to see which one performs the best. In a video announcement, YouTube says it’s currently testing the feature with “a few hundred creators,” but plans to roll out a beta version in the coming months to thousands more ahead of a broader launch next year. YouTube says the functionality, which is often known as A/B testing, has been a “top requested feature” by its users. A video’s thumbnail plays a vital role in drawing in viewers, meaning there’s pressure to make it as appealing as possible. A screenshot of the in-development YouTube feature shows how its Test & Compare feature will report back each thumbnail’s “watch time” as a percentage once it completes an A/B test. Over the years’ third-party tools have popped up that advertise letting users A/B test YouTube thumbnails.
