I want to get my self-published book out to a larger audience. How do Facebook pages and Google Plus compare as platforms for self-promotion?
Google+ is awesome. I love the communities. However, the people on there are primarily authors, writers and not people who are typically going to buy your book. Unless of course, you forge a solid friendship and force them (which I have).
Facebook is truly for fans and updates. I use both but think facebook is a better way to get readers looking at you and your work.
Twitter-eh, I'm not a big fan. So far my best social network where I get sales is from goodreads. Giveaways are really popular and do really well!
