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.
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.
Acknowledge and appreciate your readers especially regular readers by replying to comments and visiting their work.
