YouTube is testing a new feature: discover videos with previews

When you click on a video, before you are able to watch it in its entirety, you will be able to view a "trailer" first.

YouTube doesn’t want to budge an inch of ground in the battle for user attention.

And with this new feature, it only serves to prove it.

Discovering Videos with Previews

The primary objective of this feature is to prevent “sensationalist thumbnails”, to which we have become so accustomed on YouTube, from leading users to watch videos expecting one thing, only to find the reality is entirely different. For example, in these videos it is highly unlikely that you will see a clone of Mr Beast, or that old woman running on an athletics track, nor will you see 100 pilots climbing a kind of pyramid with a private jet on it.

With this feature, the platform will display short clips that better highlight the actual content of the video, thanks to its algorithm. In other words, when you click on a video that appears on YouTube’s homepage, instead of going directly to the full video, you will first watch a “trailer.”

For creators and brands, this slightly changes the landscape. The thumbnail and title are no longer the only elements that matter; now, the algorithm’s ability to select the “standout moment” of the video will be crucial for retaining users. This makes the process somewhat more challenging for them. However, for users, this may provide an effective way to further filter the content they consume and avoid the endless scroll.

From this preview screen, users will be able to:

  • Go to the full video.
  • Add to “Watch Later.”
  • Quickly interact with the content.

At present, this feature is available on the YouTube mobile application for Android for a small percentage of users.

By facilitating the discovery of long-form videos through “Short”-style previews, YouTube aims to ensure users never feel the need to exit the application in search of information or entertainment elsewhere. For marketing professionals, the lesson is clear: content must now be more modular and visually compelling than ever, as a user’s first interaction with our brand may be through an automated preview.
