My experiences with paid advertising have been mediocre, but in those cases, it's usually been a single random add posted now and again. Now I've planned a promotion blitz with my novel, The Kult, starting next weekend. I'm using lots of sites to see whether combining them over a few days will work better (of course what works for one book won't work for another and there are lots of variables).
So first, the stats. The Kult has been out for a few years now, but I've decided to give it a big push. The story has been filmed by an independent production company and is currently in post production. On Amazon.com it has 28 reviews and an average of 4.4 stars. On Amazon.co.uk it has 25 reviews and an average of 4.4 stars too. (On Goodreads it has 191 ratings with an average of 4.02).
Now I've already reduced the price from $2.99 to 99c to avoid any mishaps for the planned week, and I'm promoting utilising the following sites:
(I've also contacted the following sites, but promotion is not guaranteed and I've not heard back from them at the moment: http://www.pixelofink.com) and http://blog.booksontheknob.org/)
Of course I'd love any help people can give me by reposting any ads or links they see during the promotion.
The total cost of this promotion blitz is $613 (£393) and to recoup my costs I've got to sell 1751 copies. I'll post the results after the event. And here's a couple of links to the books:
