Have you tried iAuthor?
I don’t plug many services here, but I signed up for iAuthor earlier this year. I liked the idea and it was free, so I figured I had nothing to lose.
So I added my books, added them to some themes and then I sorta forgot about them. I had other books to write and edit. Not to mention day job, and you know, living a life in general.
Anyway, on a whim, I decided to check back today, for the first time since July, when I added the Cauldron Bound. I added The Cauldron Bound to a bunch of themes and updated the blurb. Then, I discovered iAuthor’s reader stats. I could see, how often someone clicked on the links to my books. Basically, twice as made had clicked on Exile, compared to The Cauldron Bound. Sadly the clicks hasn’t lead to any sales, but it is still interesting.
Considering how inactive I am, it would also be interesting to see what happened if I became more active. Would it lead to more sales? It is something that I need to think about.
