Thanks to Hedonist Six for allowing me to refer to her blog post today, showing off some stats she has uncovered after compiling her sales data for the past year.
See the original blog post here; Exclusivity or not; are other retailers worth it?
(The figures quoted represent royalty income, not number of books sold.)
For her particular work, in her genre – erotica – the breakdown is as follows:
68% Amazon
14% Smashwords (almost exclusively Barnes & Noble since Apple has not yet added her work to its catalogue)
10 % Google Play
6% All Romance Ebooks
2% Kobo
While these results may not be indicative of how these retailers may perform for you, it’s still pretty interesting. Especially when you bear in mind that beyond linking to book listings on her website, she hasn’t done any advertisements of anything other than Amazon listings. The only significant marketing activity so far has been to just make part one of her serial novel free on all platforms, and wait for readers to find it themselves.
I did a similar thing with a poll (survey) from many authors on a blog post awhile back. Had similar results with the main difference here looking like it comes from Google sales. http://ebooksuccess4free.wordpress.com/2013/01/24/poll-where-do-indie-authors-sell-ebooks/
