Include data in blog posts. It makes the post more interesting and informative to read. It makes people stay longer on your pages and even share your content.
Keyword search: Take up a keyword search for the blog posts you are writing. Choose the ones that searched often and have less competition.
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.
