Congratulations to anyone who can get a BB.
I've tried for 100 or more BBs and never had any luck - I start for a .99 feature, and work down to a free all places then free international, but they've never looked at me. My last try was for a free promotion of my most popular book because I was releasing a sequel - it had almost 300 reviews and 85% of them were five-star and 10% four-star, so it should have ticked the right boxes (it now has 339 - same ratio).
So, I went back to Nicholas Erik's promotional list and did a stack of Fussy Librarian, FreeBooksy, Book Cave, BookDoggy, and Red Roses Romance for a free promotion - the total cost was about half a BB, I had 6,700 downloads, and the book went to #20 overall free (that position probably fueled most of the downloads) and #1 in all categories. The sequel has made nearly $2,000 in six weeks, so I'm happy with the stacked promotion.
I'd still love to try a get a BB one day, but they're not interested in any of my books. I've seen some blinking awful and ordinary books promoted on BB with barely any reviews and I figure I must have offended someone there at some stage.
