You can promote your book with hashtags on Facebook now just like you have on Twitter. The trick is to pick the right hashtags to use. You can, of course, create your own hashtags but if no one knows about your book the hashtag won’t work. The key is to get people to follow you and retweet your tweets.
A good hashtag to use when talking about your book is #book. It’s that simple. People tweet about books and book reviews on Twitter so this simple hashtag gets a lot of use. The following websites can help you research hashtags before you start tweeting or Facebooking. Let us know what hashtag you use for your tweets!
