Think of all the free traffic you’ll be getting. Each new blog will improve your website’s SEO. Writing about topics and keywords relevant to your audience will significantly better your website performance in search engines. Besides the obvious benefits of using keywords and internal linking for improving onsite SEO, regularly publishing valuable content will allow other websites to share your blog. This kind of external linking is pure gold for Google. The level and the quality of the content will affect how long readers stay on your website.
