The best method to attract traffic to your blog is to write good content regularly and share on all social media sites at a time when your audience is online.
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.
