Blogging will certainly up your SEO game. Customers love to find relevant blogs and articles on your website which are content-rich and full of valuable, actionable and authoritative information. Hosting a blog or other written content forum which gives a user access to this information is a valuable SEO tool to have in your toolkit. Customers appreciate gaining personal insight into your business and learning from you. The absence of a blog or other written content on your website will undoubtedly push your position on the search engine results pages lower.
