The about page on a website is a necessary page for any website. This is the page that contains a short biography of yourself and the purpose of your website. It’s important to keep it both friendly and professional in order to make your company seem welcoming.
On the search engine optimization side of explaining why the about page is necessary is the fact that search engines do look for this page. For example, if if exists and Google picks it up, it may become a site link. A site link in simple terms is where your search engine listing has several links listed that Google believes may be important for people needing to know about your services.
