It's been 4 1/2 years since I first released The Greatest Show on Dirt. A lot has changed since then. While I just missed the days when indy authors were riding free promos up the Amazon rankings, I saw some steady sales figures that first year, with relatively little promotional effort on my part. I went off and on between exclusivity with Amazon and branching out to other ebook retailers, before eventually settling on an Amazon-only approach about 2 years ago.
The tradeoff was worth it for me, because I never seemed to gain any traction at B&N, Kobo, Apple, etc. The little revenue that had ever trickled in from those sites was more than offset by the money I earned from borrows via Amazon's KDP Select program. And when that started to slow, I was able to push it back up with Amazon's pay-per-click ads, which paid for themselves once I found the right price point.
But over the past few months, those have flattened as well. And I've decided to give the other ebook retailers another crack. Effective immediately, my first two books will no longer be exclusive to Amazon. Both The Greatest Show on Dirt and Nine Bucks a Pound are already available on B&N, and I'm working to get them live on other sites as well. In time, I may go the same direction with Sorry I Wasn't What You Needed as well, though for the moment that still seems to be faring okay in KDP Select.
Publishing is a game where you need to be flexible and willing to try something different, just to see what happens. It's time for me to experiment. We'll see how this goes.
