…Which is to say, I may never figure it out.
But, sometimes advertising in the right way can give you a bump. For months Shadow Hand Blues has been buried on about page # umpteen zillion or so at Amazon. Nobody bought it, because nobody knew it existed.
Virtual Pulp took advantage of an advertising special on Kindle Nation Daily. (It’s unlikely we’ll ever use Book Bub unless their prices get a whole lot less ridiculous.)
Then on May 29 SHB reached #60 in Mysteries>Private Investigators; #76 in Suspense>Political; # 68 in Historical/Suspense; and # 8,755 paid in the Kindle Store. (The rankings were actually a little better than that before I thought to take a screenshot.) Not bestseller status, of course, but it at least moved the book up out of the enormous slush pile for a hot second where browsing readers might actually find it.
And a few did. Sales spiked for one day. What’s nice is, since the promotion ended, it hasn’t slipped completely back into obscurity. Some E-Book sales are still trickling in, and it’s accumulating some KENP (Kindle Edition Normalized Pages) read, along with its prequel, Fast Cars and Rock & Roll, which is targeted at a much narrower niche audience. Maybe one or both will pick up some reviews, as well.
