YouTube has announced the widespread availability of its new “Thumbnail Test & Compare” tool, designed to help creators determine the most effective thumbnail for their videos.
Initially launched to a select group of creators last year, the feature is now accessible to a broader audience.
With this tool, creators can test up to three different thumbnails for a new video or an updated existing one. These thumbnails will be shown evenly across viewers, allowing creators to analyze performance data and identify which thumbnail generates the most watch time. This data-driven approach enables creators to select the most engaging preview image to attract more viewers.
“Thumbnail Test & Compare” is expected to be a valuable asset for creators, especially in an increasingly competitive environment. By making informed decisions about thumbnails, creators can enhance their video’s appeal and viewer engagement.
The testing process can take from a few days to two weeks, depending on the number of impressions the video receives and the differences between the thumbnails.
YouTube advises creators to test thumbnails with distinct variations in layout, backgrounds, and text overlays to ensure a thorough comparison. If no clear winner emerges, the first thumbnail will be selected, although it can be changed manually.
Creators can utilize this tool for various types of content, including regular videos, podcast episodes, archived livestreams, and public long-form content. However, the tool is not available for private content or videos rated as mature or “Made for Kids.” Additionally, it may be challenging to get conclusive results from older videos due to potentially lower impressions compared to newer ones.
Over the coming weeks, “Thumbnail Test & Compare” will be integrated into YouTube Studio on desktop for all creators with access to advanced features, which require phone and ID verification. YouTube is also developing a mobile version of the tool.
This rollout is part of YouTube’s broader initiative to introduce new tools for creators, including an AI feature that helps skip to the best part of a video and AI-generated backgrounds and unique effects for Shorts.
