The thing with being a self-published author is that without a loyal readership you put that book you worked so hard on up on Kindle or Smashwords or whatever you want and still get peanuts. That isn't an accurate representation of the work you must have put in to the novel.
Start a blog, write about things you love and people will feel the passion you have for the topic. Gain a readership, these people will be familiar with your work. I write as often as possible. I work on my novels in between writing for this writing tips/personal blog, I write a Travel Blog and I contribute to and edit a Literary Magazine, I also contribute to a Film and Television industry blog with my brother found here.
I have multiple ways for potential readers to connect with me. Blogs and websites are a great marketing tool. You should use them.
