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.
Optimize images by mentioning the ALT Text and a short description of the image in your blog post to rank better in Google.
