If you are serious about optimising your online presence as an author, K-Lytics is worth checking out. Their site asks the following rhetorical question:
“Do you want to sell more books, face less competition, and achieve a higher return on your publishing investments?”
Their paid market reports burrow into the details of hundreds of genres and micro-genres. Seeing the maths underneath the book markets is a bit disconcerting, but in a world governed by algorithms and visibility, these insights are essential. The specificity of some of the genres and sub-genres is almost comic: Scottish Romance (what about Scottish Time Travelling Romance?); Cosy Mystery; Urban Fantasy, etc.
“You do not have to be afraid of numbers. We will help you to understand and use them to your advantage.”
