One of the best ways to get readers is to create a blog. Post on that blog at least once a week. Less and they might forget who you are.
I’m assuming your blog is on WordPress because that’s the most commonly used venue for writers. If so, then you can check out the mechanics of the site and link your blog to Twitter, Facebook, Goodreads and other social media sites so that every time you post on your blog, the post also appears on all of the other sites that you’ve linked to.
That increases your reach many times over so you’re multiplying your readers. Over time your readership can grow very large.
Or so they tell me. I’m new at this too. I’ll let you know if it works.
