For those who don't already know, Smashwords is an all-in-one platform for authors to publish and distribute their e-books. It has its pros and cons for both writers and readers, which I don't have the time to go into right now, but it is very popular in the indie community.
Authors who publish with them are able to track their sales and story sample downloads to gauge how well their works are faring on Smashwords. There's also aggregate reports of daily sales on other platforms that Smashwords distributes your work. But last year, Smashwords began collating all of that data to see if any patterns can be discerned from it or if its random noise.
Every indie author should read the findings for themselves. The data regarding price point, title length, length of book, and sales are definitely very interesting and something to be taken into account when an author publishes their work.
Anyone wishing to discuss it in the comments section, please go ahead! I've always had a fascination with statistics, which is all about finding patterns in what appears to be just random numbers. But I don't have anyone to talk to about this study. That's where you come in. :)
