Its not just good content that matters, presentation of post is very important too. Have attractive pictures, fonts etc to hook the readers.
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.
The more you share your posts on social media & the more you engage & entertain your readers, the quicker your readership will grow.
