I'm Glad I Found This Tool I've struggled to find a A/B title and thumbnail tester that does what I want it to, until I found Thumbnail Test which I have read great reviews on. I've decided I'm going to use it even when I get access to YouTube's test and compare feature, because YouTubes version only shows results using watch time, which in my opinion isn't great, I think thumbnails and titles should be assessed using click-through rate. Which is why I decided to use Thumbnail Test because of the huge range of analytics it provides.

big fan of Thumbnail Test I've been using Thumbnail Test for over a year and have run 100s of A/B tests with it. I love being able to run hourly and daily tests with multiple variations. It's helped me learn what works and what doesn't for my channel and has helped me get millions of views I otherwise would not have gotten without the insights I learned from running A/B tests with Thumbnail Test.
