Preorders are an *enormous* help to authors.
Because they’re lumped together with first week sales. And that total is a publisher’s first and primary indication of whether a book is a commercial success. Success affects things like whether a series is continued, and whether the publisher thinks the author is a good bet for future books. (Sales aren’t the only thing that go into those evaluations, but publishing is a business, and sales definitely matter.) The first week sales figure also drives NYT and USA Today bestseller status.
When I ask you to preorder, I wanted you to understand why. 🙂
