Stats: the tracker

The "tracker" is the graph that shows how well the average erotic romance ebook is selling--and how this changes across time. (The data relates to books that are currently available for sale or were on sale during the previous 365 days.)

When I first started collecting data in 2007, average first month sales were 81 copies, sales in the first year averaged 320 copies and I didn't have enough books in the data set to measure sales for books out for more than a year.

At the current time the data set includes 240 books. Average first month sales are 227 copies, average sales in the first year are 422 copies, and books out for more than a year have sold an average of 691 copies.
