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.
Blogging is a great way to interact with your readers but please avoid the SMS Lingo white creating your content.
Focus on good content, not on monetization. Over time, money and benefits will follow good content.
