I’ve learned that keywords for books uploaded to Kindle don’t have to be single words, the phrases vampire mystery, paranormal suspense would be counted as two keywords by the system if they’re separated by a comma, so with this in mind I’ve set about changing my keywords.
I’ve also been using a technique which involves typing keywords and phrases into the Kindle Store search box to find sub-categories with fewer books in them. (Fewer books, but falling under popular keyword phrases.) However, I’ve discovered something that may or may not be, let’s say . . . not quite cricket!
