One of the things writers give a lot of thought to after they've finished writing a great book, is finding readers. Whether you're traditionally published or you're going it on your own, promotion is going to be a concern unless you're already so well-known your name comes up in game quizzes and thousands of people have you on automatic buy.
We all know the benefits of social media - Facebook has helped quite a few readers find me and remains my main platform but I also have a blog, Eugenia Writes!. And on that blog, I often explore a few of my other passions like photography. Almost every Saturday, I'm one of the participants in the Snapshot Saturday blog hosted by Alyce of At Home With Books and, now and again, when I can find an orange photo I join the lively group participating in Orange You Glad It's Friday. I love taking pictures and would participate anyway but a couple people also participating in those memes are now among my Google followers. It doesn't mean they'll buy my books but it does mean that my name recognition rises just a little bit higher every time I'm involved in a meme.
Writers are not one-dimensional people (at least, not usually)! Share your other interests with others. If you love cooking, if you're an avid RVer, if you regularly go spelunking - blog about it, tweet pictures, Pin them. Share articles about your issues and concerns on Facebook. You'll be surprised at how many new readers you might pick up that way but even if you don't pick up a single one, you're blogging and tweeting about what you love. Where's the downside?
