Novelrank is a bit less accurate than Amazon's own reporting. Remember, what they're really tracking is the sales ranking, and estimating from that. They don't have the actual book sales info. That you can get from Amazon. It's a good way to track other people's books, though.
I tried it just to see and must say that at face value it looks okay. I even like the little barcode that allows me to check my stats via my BlackBerry.
What I don't like about it is that there doesn't seem to be a way to remove the book from the site. Does anyone here know how to do this?

[b]How do I remove my book from NovelRank?[/b]
Contact me at email@example.com and if you are the original author, I can remove it. However, be aware that it can be added again by anyone (I will not put blocks on tracking particular books).
I'm also not sure how comfortable I am with people being able to see a rough estimate of my sales. At this moment it's fine, as I sell about one copy every 70 years or so, but there will come a time when people will buy my books just to get rid of the annoying marketing and when that day comes, I'd like to keep it to myself...
Oh yes... and it seems that nothing prevents just about ANYONE to slap in your novel's URL and then just sit back and watch the figures. No verification. Nothing.
Not sure how anyone else feels about this...
Perhaps I'm just paranoid because I know that The Son of Perdition cometh (see what I did there?) heh!
