Before & After: How Cover Redesigns Improved Book Sales

A book cover before and after a professional redesign

Key Takeaways

  • A cover redesign can revive a book that’s selling poorly, often the cover, not the writing, is the problem.
  • The most effective redesigns fix genre signaling, thumbnail readability, and professionalism, not just “make it prettier.”
  • Signs your cover is underperforming: low click-through, good reviews but weak sales, or it looks dated next to comps.
  • A/B testing lets you compare covers with real readers before committing to a full relaunch.
  • A redesigned, genre-accurate cover is one of the cheapest ways to lift sales on an existing book.

Sometimes a book that deserves to sell just… doesn’t. The writing is good, the reviews are positive, but sales stay flat. Surprisingly often, the culprit isn’t the story, it’s the cover. A cover redesign is one of the highest-leverage moves an author can make on an existing title, because it directly affects whether readers click at all. Here’s why redesigns work, what a real before-and-after looks like, and how to know if your cover is holding you back.

Book cover redesign
A book cover redesign is the process of replacing an existing book’s cover with a new one, usually to better match genre conventions, improve thumbnail readability, and look more professional, in order to increase click-through and sales on a title that’s already published.

Why Authors Redesign Covers Post-Launch

Most authors don’t get their cover perfectly right the first time, especially if the original was a DIY or budget design. Common reasons to redesign after launch:

  • Disappointing sales despite good reviews, a classic “cover problem” signal.
  • The cover doesn’t match the genre, attracting the wrong readers (or none).
  • It looks dated compared to current bestsellers in the category.
  • It’s unreadable as a thumbnail, where most discovery actually happens.
  • Rebranding, the author is building a series or a consistent author brand.

Case Study Breakdown (Design Choices + Outcome)

Here’s a representative before-and-after that mirrors what we see again and again with underperforming titles. (Figures are illustrative of typical redesign outcomes, not a guarantee.)

ElementBefore (original cover)After (redesign)
Genre signalGeneric, unclear genreInstantly reads as the right genre
Title legibilityThin font, vanished at thumbnailBold, readable at 150px
ImageryCommon stock photoCustom, genre-specific artwork
Overall feelHomemadeProfessional, on-trend
Typical resultFlat salesHigher click-through & conversions

The key insight: the redesign didn’t just look nicer, it fixed communication. It told the right reader, at a glance, “this is the book you’re looking for.” That’s what moves the needle. (For the principles behind it, see what makes a book cover sell.)

Signs Your Current Cover Is Underperforming

How do you know it’s the cover and not the book? Watch for these signals:

  • Good reviews, weak sales. Readers who buy enjoy it, but too few are buying. Often a discoverability/click problem.
  • Low click-through on ads or your retailer page, people see it and scroll past.
  • It looks different from the top sellers in your category (and not in a good way).
  • The title disappears when you shrink the cover to thumbnail size.
  • Readers misjudge the genre when you show them the cover cold.

How to A/B Test a New Cover

Before a full relaunch, you can test a new cover against the old one to make a data-informed decision:

  • Reader polls: show both covers to your genre’s readers (newsletter, reader groups) and ask which they’d buy and what genre each signals.
  • Ad tests: run small, equal-budget ads featuring each cover and compare click-through rates.
  • Thumbnail lineups: place each option beside current bestsellers and judge which belongs and stands out.
  • Then commit: once one clearly wins, update the cover everywhere, retailer pages, ads, and your author brand assets.

Remember to update both formats correctly, the new design needs proper eBook and print specs (spine, bleed, and resolution) so the relaunch goes smoothly.

Frequently Asked Questions

Can a new cover really increase book sales?
Yes, often dramatically. The cover is the first thing readers see and the biggest factor in whether they click at all. If a book has good reviews but weak sales, the cover is frequently the bottleneck. A redesign that fixes genre signaling, thumbnail readability, and professionalism can lift click-through and conversions on an existing title, making it one of the cheapest ways to boost sales.
How do I know if my book cover is underperforming?
Watch for these signs: good reviews but weak sales, low click-through on ads or your retailer page, a cover that looks dated next to category bestsellers, a title that disappears when shrunk to thumbnail size, or readers misjudging the genre when you show them the cover cold. Any of these suggests the cover, not the book, is the problem.
Why do authors redesign their book covers after launch?
Common reasons include disappointing sales despite good reviews, a cover that doesn't match the genre, a design that looks dated next to current bestsellers, poor thumbnail legibility, or rebranding for a series or consistent author brand. The goal is usually to fix communication, telling the right reader at a glance that this is the book for them.
How do I A/B test a new book cover?
Before a full relaunch, compare the new cover against the old one: poll your genre's readers on which they'd buy and what genre each signals, run small equal-budget ads featuring each cover and compare click-through rates, and place each option beside category bestsellers in a thumbnail lineup. Once one clearly wins, update the cover everywhere.
