Most buyers these days will not consider a new title without seeing a comparative title along with it. Buyers use the comparative title to inform them about how well books similar to your new title have done, and draw a conslusion on how much to buy. Here are some guidelines on how the select the most effective comparative title to maximize sales of your new titles:

• Choose a comparison book, or books, from the same genre as your new title, same series, or by the same author that sold well. 
• The comparative title must have sold well the month before release, the month of release, and the month after release.
• The comparative title must be in the same price range as your new title.
• Comparative titles must not be published more than 3 years before your new title.
• The comparative title should ideally be placed next to your new title in both your catalog and tip sheet.
