This is an example page. It’s different from a blog post because it stays fixed in a certain place and your theme’s title is displayed in your navigation menu (most themes support it). Many people use an About page to welcome their potential visitors. A page that looks like this:

Company XYZ was founded in 1971 and has been producing quality items since its inception. XYZ, which is located in Gotham City, is trying to do everything best for Gotham City with its more than 2,000 employees.
