NovelRank for iPhone – the Amazon sales rank tracking app – enables authors, publishers, and book marketers to track and compare the Amazon sales rank statistics for printed books and Kindle Edition ebooks across several Amazon country sites. The app supports tracking through free NovelRank.com user accounts, which can sort books by title, sales rank or last sale. The app also provides a graphical history of daily sales estimates and hourly sales rankings.
If your book’s web site, blog, Twitter, and Facebook Page drive traffic to your Amazon book page, then tracking your sales rank history via NovelRank is a great way to determine if and when your online marketing tactics are effective. It’s also a convenient way to compare your book’s sales rank with competing books.
Available as a free app download on the iOS App Store. If you want to try out the app before creating your own free NovelRank.com account, then within the app, simply assign the user account name to: demo
