The sales page for your book is extremely important.
It should attract visitors and entice them to buy. But keep it simple. Website visitors have short attention spans. You don’t need big, bold headlines to sell a book. You need really great sales copy that makes a reader think, “I need this book!”
Use this checklist to make sure you include the elements on your sales page that make potential buyers become buyers.
