Don't just pick a winner — learn why it wins. We test your cover concepts with real readers in your genre and show you exactly which elements drive clicks: imagery, typography, color, composition.
Sample of the element-level report you receive.
Your designer sent three cover concepts. You picked your favorite — but your favorite isn't your reader's favorite.
A poll told you Cover B won. It didn't tell you why — so you can't apply the lesson to your next book, or your series rebrand.
Your ads underperform and you can't tell if it's the hook, the targeting, or the cover doing the damage.
