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.
Blog Title: The shorter your blog title the better it is. Include keywords in your blog title and keep the mystery alive while you hint your message.
Originality - Focus more on the originality of content and on a consistent basis. It is a habit you will need to cultivate.
