In January 2013, when I published my first WW2 spy story, The Back Orchestra, on Amazon KDP, my sales were pretty abysmal: Jan sales: 19, Feb sales: 21
On the last day of February, I revised the two Categories allowed by Amazon at that time and chose a new set of Keywords for Amazon. Following these changes, sales of my book showed an immediate improvement: Mar 190, Apr 415, May 407, Jun 408, Jul 407, Aug 352, Sep 327, Oct 306, Nov 263, Dec 1,077 (including 421 in a Countdown Promotion). Total sales for 2013: 4,192
Things have changed quite a bit since then. Nowadays, Amazon allows 10 Categories for an eBook and 10 more for a paperback. Keywords, which used to be single words, may now be phrases with a limit of 50 characters. And Amazon will juggle and combine the individual words in a phrase to match enquiries keyed in by readers. Also, it is now possible to advertise your book directly on Amazon, using your own carefully selected keywords. The bottom line is that there are now many more ways of reaching our readers, but the selection processes are a lot more complicated.
This inspired software will do all the work for you, and more. PublisherRocket mines the Amazon database in several different ways to help find suitable categories that will maximise the chances of your book making it to the top of a category, to help identify keywords for your book and for advertising on Amazon Marketing Services.
