Every business needs an About Us page. Some need more than one. Maybe you would like to have this page be about your company and have another page that features your team, and another one that explains the history behind your company or product.
For the additional pages, choose this page as the Parent page when you create them to keep things in order. You will have to add these pages to the menu too. Check out the WordPress tutorials on Champlain Host if you’re not sure how to do that.
