So, what do the results look like five days afterward?
I took this screen shot of the Top 20 in the Action Adventure genre of Sea Adventures, yesterday afternoon. This is a smaller part of the Action Adventure category and usually represents the Top 20,000 in the Kindle Store. The Top six spots in this genre require a good 5000 overall rank in Amazon's Kindle store. Before last week's promo, my six books were stretched from Fallen King, which had held the #1 spot since it was released on 2/14, to Fallen Out at #19, with an over all rank about #20,000.
Sell through from last week's promo has brought all six to the top in the Sea Adventures genre, which they still hold in a different order, today. Fallen Out took the top spot from Fallen King, the day BEFORE the BookBub ad on 3/19. The two have held those spots since, currently #944 and #3564, respectively, in the Kindle Store, with the others still scrambling around in the #3 to #6 spots.
Current Sea Adventures Top 20
From past experience with this same book in a promo set up in the same way, I had very similar results. I know a lot of you are ranking lower and wondering will this type of campaign work for your books. Results will vary, but it will work better than just applying to every advertiser you can, without planning the promo ahead of time and carefully filling the time slots. Not always with the best producer for that time slot, but with one that will produce slightly more sales than the previous ad did, but won't produce more than the following ad.
Hope this helps and gives you some motivation. Keep Writing.
