When it comes to promoting your self-published book, nothing beats free! Here’s a quick little site where you can submit your book information for a free listing. There are a lot of these types of sites out there, but this one belongs to Dan Poynter, who promotes endlessly and drives many, many people to his website all the time. It will take about 5 minutes of your time. While you are on his site, I recommend exploring other options and opportunities he has available.
