Research: Use blogs that publishes content that is based on research ans is relevant to what your topic is.
The more you share your posts on social media & the more you engage & entertain your readers, the quicker your readership will grow.
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.
