TitleZ is a handy tool for evaluating book topic ideas because you can gauge the potential audience for a given topic or title. Using TitleZ you can easily assemble a list of related books with their historical sales rankings and descriptions. This indicates whether other books on the topic have succeeded or failed, and may show where opportunities exist or where markets are saturated.
TitleZ also provides pricing information on competitive titles, helping you determine the right price for your book. You can also track your book's performance over time to assess the effect of promotional efforts and marketing programs.
