The way to go

Lots of writers are turning to ads because book sales are so slow. Google, Facebook and Amazon seem to be the top choices. I think it may have a lot to do with the way Facebook changed the ground rules about who saw which posts - the answer being the average person saw very little, certainly when compared with what had gone before. Time was when it was hard to actively keep up with the number of posts scrolling by - and maybe that volume threatened to break the system.
I deliberately did not do any promotion this autumn. I thought I'd save my efforts for when the new book was published. With no promotion my sales line looked thin, though the odd KENP figures chipped in randomly. Certainly no way to go on if I want my books to be read. I have followed a couple of webinars with Mark Dawson, but to follow the method he advocates you have to be prepared to speculate to the tune of $99 to join Amazon Advantage and it seems to me it is geared to selling paperback books rather than e-books. So I shall be doing a little more reading around the topic..

Ads, anyone? What do you think? Is it the way to go?
