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.
Put advertisement but make sure that your blog visitor doesn't get irritated when ads pop up one after another like a flood.
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.
