Blogs are a key part of search engine optimization as you’re able to convey more ideas and input original content since it is being written about a topic that you have knowledge of. This, in turn, helps your website rank higher because the more relevant information that you provide, the more likely people will link to your site or even write a blog post about it. This drives more people back to your site and allows you to rank higher in the search engines for keywords related to your blog posts.
