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.
Photos are the most essential part of your blog or post. Take clear pictures on a light background to keep the focus on the product.
Remember that content is the key to a successful blog. Quality scores over quantity in getting audience to your blog.
