The increase in sales from the BookBub ad was across the board. Google Play downloads skyrocketed with reviews indicating readers found it from the BookBub ad. I don’t know what Apple downloads of Ghosts were like, because it’s posted through Smashwords and they deliver numbers slowly, but Apple downloads of the later books (via Draft2Digital) went from a grand total of 7 units in April to 127 in May. And B&N was lovely–I earned over $1000 on B&N for the first time.
Today, though, marks a Kobo milestone: sales yesterday mean that my lifetime Kobo income broke $100. It’s a small success, but exciting nonetheless.
