Noah Kagan’s Million Dollar Weekend Book Cover Split Test

Look at this “Split Testing” Noah Kagan did to find the right book cover:

He also ran Facebook Ads to test which book covers/colors people would click on the most:

He also also got a bunch of variations of the book cover made, did audience polls which one was was the best (almost immediately the snapping fingers won), and looked at them as tiny thumbnails like a shopper on Amazon on their phone would see:

The end result looking like this!
