Amazon has released some data designed to boost interest in the KDP Select program. Apparently, books enrolled in KDP Select earned – on average – 77% more in terms of paid royalties during August than in the three months before they were part of the program.
In other words, being part of KDP Select aids discoverability… or at least, that’s what Amazon is claiming. The logic would seem to be that KDP Select borrows allow books to gain exposure via word of mouth, and also make it more likely (though by no means guaranteed) that they’ll pick up a few reviews.
That 77% figure is quite impressive, assuming it excludes earnings from borrows (the language used by Amazon in the announcement is a little vague). As ever, it seems that KDP Select really works out well for some authors, although some are still left with little to show for their exclusive deal.
