Create a FACEBOOK AUTHOR PAGE. This is where you can send blog posts from your website.
You will need a banner photo as well as an author photo, probably the one you use for your book.
After posting a blog entry on Wix.com, it allows you to select a Facebook page you manage, your personal page, twitter, Linked In and email to post your blog. It’s incredibly convenient. Also on your Facebook Author Page, create events and post photos and ads that you create. As I said in an earlier post, if you see an ad for a book that you like the look of, copy it.
Invite your friends from your personal page to like your author page to grow your audience.
I tried to sell books using Facebook ads but had no sales so I stopped, but that might not be your experience. You could get more traction than I did.
