🎥 Video: What's Thumbnail Test like?

Above is a video that shows what it's like using Thumbnail Test.

What if you video could have gone viral - but it just didn't have the right thumbnail.

And even worse: what if the right answer was, in fact, that 2nd or 3rd idea you've had for the thumbnail - but you just went with another one.

After
Before

Before Thumbnail Test

You’re just guessing which thumbnail works best
You can only wonder if your video has missed out on it’s true, maximum potential
You get into “analysis paralysis” regarding a thumbnail + title combination
Your gut feeling is your best choice
With your thumbnail + title combination, your video either does well OR it’s slowly becoming irrelevant

After Thumbnail Test

You know which thumbnail performs best, thanks to tests
You now know you’re reaching your video’s maximum potential
Your video either goes viral OR you know there’s something else you have to tweak
No more gut feeling - data confirms calculated decisions
You can revive old videos which are underperforming, thus reaching max potential

“HOLY SH!T Just found the GREATEST website for YouTube Title & Thumbnail A/B Testing 🤩 You can test EVERY video on your channel (the website changes it for you) Then see which performed the best and get the most out of your content :) And HALF THE PRICE OF COMPETITORS 😳”
ElectricityWave
@ElectricityWave
“A website like this is every Youtuber's dream because it literally gets you more views. Especially since I'm in such a competitive gaming niche, analytics are super important to study. Having the ability to do tests has saved videos of mine that were underperforming.”
Garfield
@garfieldisdoc
“ThumbnailTest has been an incredible tool for me and my teams as it saves time and lots of guesswork by finding the highest-performance thumbnail for our video and letting it perform the way it should. Could not recommend this tool enough for any person or team that is looking to increase their CTR and views.”
Vexian
@Vexian
“As a creator who focuses on making and saving money, I have to make intentional decisions about where I want to spend my money in my creative process and Thumbnail Test is a no brainier. It's become such a standard part of my creative workflow that I even use it to test older thumbnails. It's truly worth every penny.”

FAQ

How does it work?

We store all the thumbnails you upload.

Every day at midnight (or every hour throughout the day), we change the thumbnail on your chosen video to the next thumbnail in the list.

At the end of the test, we look back at the click-through rate, views, and other stats each thumbnail got, and give you that data to decide which thumbnail performed the best.

🎥 Video: What's Thumbnail Test like?

Above is a video that shows what it's like using Thumbnail Test.

What if you video could have gone viral - but it just didn't have the right thumbnail.

And even worse: what if the right answer was, in fact, that 2nd or 3rd idea you've had for the thumbnail - but you just went with another one.

What is A/B Testing?

Normally, an A/B test is when you show 100 people something, 50 see A and 50 see B, then you judge if A or B is better based on their reactions.

Therefore, a thumbnail A/B test means we show thumbnail A for one day/hour, then thumbnail B for one day/hour, and repeat that for a couple weeks.

At the end, we see which thumbnail more people clicked on.

What can I expect from this tool?

This tool is not an "autopilot" function, rather it's a tool to run tests.  

Make different thumbnails, come up with new titles, and then this tool can do the heavy lifting to tell you what’s working.

The best thing you get out of this tool won’t be necessarily views - it will be understanding what your audience actually wants.

Can’t you do this in YouTube already?

Correct, but:
‍
• YouTube's feature is only for thumbnails, not for title (or titles + thumbnails)
• YouTube's feature is only for max 3 thumbnails (as opposed to 10+ with us)
• YouTube's feature doesn't give any granular control - you'll only be able to add 3 thumbnails and that's it.
• YouTube’s feature shows only one metric, vs 20+ with us

In short, YouTube's feature is great for a free start.

However, Thumbnail Test is the Pro version that helps you unlock the full potential of A/B testing. See the full comparison here.

How many videos can I test?

As many as you want. The only limit is one active test per video.
