Article last updated on:

Yes, you can automatically change YouTube thumbnails. Though, you have to use a third-party tool like Thumbnail Test — it sends each thumbnail to different parts of your audience.

FYI: YouTube doesn’t have an official feature yet, that’s why we’re using third party tools.

Let’s see how it works!

How to Automatically change Thumbnails

  1. Go to ThumbnailTest.com
  2. Log in through your YouTube Account
  3. Select a video
  4. Begin a test → Upload a few thumbnails
  5. Select the thumbnail changing frequency
  6. Apply changes

This is also known as A/B Testing for thumbnails.

It’s very simple! You just need to have a couple of good thumbnails and start a test.
