E-commerce bloggers can gradually choose to write curated content from other websites/blogs. That always helps because a buyer will generally not spend much time surfing. He/she will appreciate it if you provide most of what they are looking for.
Follow up on comments you wrote on posts. Continue the conversation. Bloggers enjoy engaging with their readers.
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.
