Every type of testing, explained

Let’s break down each.

1. Test and Compare

Test and Compare is a new feature on YouTube that allows creators to A/B test different thumbnails for their videos.

  • Benefits: Grabs viewers’ attention, helps pick the most effective thumbnail, boosts video views.
  • Availability: Rolled out gradually in 2023, expected to be available to all creators “by late 2024”.
  • How it Works: During video upload, you can choose “Test and Compare” (under the thumbnail upload section) to compare up to 3 thumbnails. YouTube will then show these thumbnails to different audiences and measure which one gets the most watch time.
  • Outcome: The thumbnail that leads to the highest average view duration wins the test.

2. A/B Testing

A/B Testing is a method used by YouTubers to experiment with different thumbnails and titles for their videos.

The goal is, as always, to find the most performant version of each video.

Benefits of A/B Testing:

  • Improved video performance: By testing different elements, you can identify what grabs viewers’ attention and keeps them engaged. This can lead to more views, likes, comments, watch time, and ultimately, a more successful channel.
  • Data-driven decisions: A/B testing takes the guesswork out of what works for your target audience. You get concrete data to see which variations resonate better, allowing you to tailor your content for maximum impact.
  • Increased audience engagement: When viewers find your thumbnails and titles compelling, they’re more likely to click on your videos. A/B testing helps you optimize these elements to spark curiosity and draw viewers in.

3. Split Testing

Split testing on YouTube is a method creators use to experiment with different elements of their videos and see which ones resonate best with viewers.

It’s not a specific built-in feature like “Test and Compare” for thumbnails, but a broader strategy.

Benefits of split testing on YouTube:

  • Data-driven decisions: Helps you choose the most effective elements for your videos based on actual audience response.
  • Improved performance: Leads to higher click-through rates, watch time, and overall engagement.
  • Content optimization: Allows you to refine your content strategy based on what resonates with your viewers.

When to use which term?

In many cases, you might use these terms interchangeably. But if you need to be precise, consider the following

  • Use “test & compare” for the general concept of testing variations.
  • Use “A/B testing” when you’re specifically comparing exactly two variations.
  • Use “split testing” when you’re comparing more than two variations, or the changes being tested are more complex.

Hope that explains!
