It's important to start making an email list so you can send out blog posts, ebooks, products, etc to your audience. Share your posts on social media like Twitter, Instagram, Facebook, LinkedIn, Google plus, Pinterest. If your blog is image heavy, Instagram is the best tool. I personally use Twitter and Instagram the most. I also like to share my blog on forums like reddit and other niche related forums. I write about beauty, fashion and fitness, so your readers might be different than mine.
