This is great for the indie author. Sales Rank Express offers visitors an up-to-the-second snapshot of a book’s Amazon ranking. But this isn’t the same as other ranking sites, it’s easier. Plug in the author, title, ASIN or ISBN to view a book’s ranking…and other data. It will show reviews, any different versions of the book, its release date, other books it might pair with, how many minutes long it is in its audio format, pricing, and more. You can even track its progress! Did I mention that it will do this for titles released internationally? Check it out, root around, have fun.
