So, you've written a great book. Now people will just automagically discover it and suddenly you'll be a best selling author, right? Not surprisingly, it's a bit more complicated than that. We wanted to give you a little advice, based on our experience working in digital publishing. Today, we'll look at how to spread the word through social media.

First of all, which networks should you be on? Most of our resources focus on Twitter and Facebook because that's where the people are. That being said, if you have a niche book, do think about niche communities you can reach out to. Also, if your book has great visuals consider Pinterest — not because everyone's talking about it — but because it's an amazing way to share and promote images.
