Most authors treat covers as artwork, not conversion engines — and pay for that with lower sales. In this episode Dan Desmarques gives a practical, publisher-focused playbook: five low-cost, KDP-safe split-tests you can run before launch to choose a cover that actually sells. You’ll get step-by-step guidance: how to benchmark your category, design three purposeful variants (genre-accurate, bold differentiator, reader-targeted), run rapid micro-tests (newsletter splits, PickFu, cheap social ad micro-buys, and landing-page CTR checks), interpret the right metrics (thumbnail CTR, sample reads, preorder rate), and choose the winning cover without guessing. Includes a concise 22 Lions case study showing measurable conversion lift, a 20-minute action checklist to start today, and immediate next steps if you want a done-for-you cover audit. Practical, ethical, and built for authors on tight time and budgets.
