Frequently Asked Questions

How accurate are TubeBuddy thumbnail and title A/B tests?

To be declared a winner in a TubeBuddy YouTube A/B test, a thumbnail, title, or other variable must reach 95% statistical significance. In other words, we’ll only declare a winner when we're sure the performance difference can be attributed to the thumbnail, title, or other variable you’re testing.

If you're confident in the results before the YouTube A/B test reaches statistical significance, you can declare an A/B test winner at any time.

Will running frequent A/B tests negatively impact how YouTube's algorithm perceives or ranks my videos?

Not at all. TubeBuddy will show your variations to a small percentage of your potential viewers (around 50%). When it comes to thumbnails, if a variation is worse than the control (the original thumbnail), fewer people will click on it.

However, metadata tests are a bit more risky as changes to your title, description or tags will cause your video to temporarily drop out of search results while YouTube reindexes it. This can take between a few minutes to a few hours.

In other words, A/B test YouTube thumbnails frequently, A/B test YouTube metadata (title, description, tags, etc) intentionally.

Is the feature user-friendly, especially for those who are not tech-savvy or familiar with A/B testing principles?

Definitely! Running an A/B test with TubeBuddy is as simple as defining:

  1. What you want to test—a thumbnail or metadata (like title, description, or tag)
  2. How long you want to run the test—for a given amount of time (like 14 days) or until it reaches statistical significance
  3. The new elements you want to test—e.g., adding a new thumbnail
Once you do this, your tests will be ready to run. After achieving statistical significance, your video will automatically be set to the winning version.

How much traffic or how many views are required for the A/B test results to be statistically significant?

Statistical significance is a standard mathematical calculation that lets you know when one version of the test has a 95% (or better) chance of outperforming the other in the long run.

TubeBuddy defines statistical significance based on video impressions and clicks. Before a test reaches statistical significance, both the control and variation must get at least 500 impressions.

These impressions come from YouTube's search results and third-party video suggestions. If your videos are SEO-optimized, your tests could reach statistical significance in as little as a few days.

Could frequently changing metadata and thumbnails confuse my subscribers or regular viewers?

Not at all. YouTube users will only see one version of your metadata or thumbnails, so they will never know you're running A/B tests.

Are there any limitations to how many A/B tests I can run simultaneously or within a given time frame?

TubeBuddy Legend users have no limit on how many tests they can run on titles, descriptions, or thumbnails per month or in total. However, there is a limit of 10 A/B tests running at any given time.

For example, you could run five thumbnail tests for five videos, three title tests for three videos, and two description tests for two videos. In total, that'd be 10 tests.

As your tests finish (depending on the time limits requested), you can create more A/B tests.
