Late last year, Facebook rolled out a big algorithm change, which scared a lot of authors. It sank a lot of pages in terms of visibility, changed how authors sell more books and book marketing goals in general.
The thing is, while social media sites like Facebook are great, to use them exclusively in your promotion is never a good idea. Because if you lose the page, or if Facebook changes this or that, or whatever social media site you’re on, you’ve now lost a big share of your market.
Never put your success in someone else’s hands.
