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.
Originality - Focus more on the originality of content and on a consistent basis. It is a habit you will need to cultivate.
Blogging is as much about bold ideas as it is about creative expressions, Work on your language and dive into ideas fearlessly.
