Use technology - Social plugins and SEO tools are a great thing to market your blog or a blog post. If you do not know about it, then learn it. It helps you reach out your audience in a better way and also improves the ranking of your blog.
Write regularly, neither too often nor too rarely. Two to three blogs a week is a good frequency to maintain.
Be awesome. There's enough mediocrity out there. Stop adding to the noise and do something outstanding.
