How can you A/B test a video on YouTube?

In this post, we’ll see how can you A/B test a video on YouTube. I believe you do have a YouTube channel but you are not happy with your channel traffic/subscribers and looking for a way to improve your YouTube search rankings, traffic, and subscribers.

A/B test a video on YouTube will definitely help you in improving your YouTube channel growth.

What is A/B testing?

A/B testing (aka Split testing/Bucket testing) is a method of comparing two different data sets and find out which one performs better . Data sets can be anything( Web app, mobile app, video, thumbnail, etc.,).

During A/B test, first set of data will be shown to the users for a specified time interval and then the second set of data will be shown to the user for the same period.

The time interval is not a fixed one, you can run the test for 10 days or 1 month as you wish. But certainly, longer the time leads to more accurate results.

Then, you should compare the results of two data sets and find out which one is bringing more revenue/traffic/sales/views according to your needs. Finally, you can go with the one which performs really good.

Let’s say you are creating a mobile app and planning to launch a demo video for the app to put on your Website. You have two different videos in your hand.

One is an animated video and another one is head talk video. You are not sure which one does your customer like and you want to try out both.

In this case, you can go for A/B testing, show the animated video to your customer for 10 days and later show the head talk video for the next 10 days.

Finally, compare the watch time, user interaction, conversion, engagement, CTR and other signals and go with the one which brings more outcome to you.

Why You Should A/B Test a video on YouTube?

Youtubers are spending a lot of time on creating content for their YouTube channel but most of them haven’t seen huge success. Because they don’t know what the audience is looking for.

This is why you must A/B test a video on YouTube if you are very serious about your YouTube channel growth. Let’s see how to A/B test a video on YouTube.

AB testing Youtube metadata

When I A/B test a video on YouTube, Tubebuddy suggested me to pick the original version of the thumbnail. Since CTR of the original version is outperformed by 30%  compared to variation.

But there is no compulsion to go with the recommended one, you have an option to set the other one as final.

When I analyze the A/B testing report, I found that except CTR other metrics like impression, watch time and view count are comparatively high for the variation set rather than the original. I mainly concern about my watch time rather than CTR so I decided to go with a variation set.

You can just click on the “Set video to variation” and it’ll get updated on YouTube within a few seconds.
