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 all about sharing; no matters if the blog post is written by you or not. Keep spreading the good vibes for your readers.
Blogging is a great way to interact with your readers but please avoid the SMS Lingo white creating your content.
