I came across this article on Forbes which is about a very successful British Self-Published Author Mark Dawson. Mark makes hundreds of thousands a year from his self-published book series.
He explains that it’s mostly about his marketing tactics, and unsurprisingly Facebook being the most effective.
I’ve used Facebook campaigns in the past to advertise specific posts and my Facebook pages, and it is effective, so I would definitely agree with Mark. Only thing that differs between us is that I don’t make as much money as him!
This is a very useful article to read so go and have a look at what Mark Dawson had to say about his success and how he did it.
