Invest in five sample copies to test consumer appeal. This Professionalism Book Test is fairly inexpensive by using a POD (Print On Demand) company.
Test 1: Place your book with books of similar content at the public library. Lay three books including yours on a table or face out on a book shelf. Sit far enough away to observe and not look like a stalker. Take notes. Do library patrons overlook, preview, read, or check out your book? Feel honored if your book reach the circulation desk.
Test 2: Visit your local book retailer. Ask for the top three books in your genre. Find a comfortable corner and critique your book. Don’t mark in the bookseller’s books, only your own. Is your writing professional (typos, misspellings, etc.)? Does your layout follow industry standards (margins, text flow, etc.)? Do your illustrations/photos match or exceed the professionals? Place your book on a bookshelf next to the competitors. Which book is most easily read from twelve feet away? If your book is week in any area, make adjustments now!
