Interact with your readers! Reply to their comments, emails and queries. Acknowledging your reader will make them come back to your blog again and again.
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.
E-commerce bloggers must carefully write keeping their audience in mind. Everything you post on your blog will speak for your product or service. Your interaction with bloggers in comments and otherwise will give you a direction.
