This is an example page. It is different from a blog post because it stays in one place and appears in your site navigation (in most themes). Most people start with an “About” page that introduces them to potential site visitors. It might say something like this:

Hello ! I’m a bike messenger by day, an aspiring comedian by night, and this is my website. I live in Los Angeles, I have a great dog named Jack and I love piña coladas. (And get caught in the rain).

…or something like that:

XYZ Doohickey Company was founded in 1971 and has been providing quality doohickeys to the public ever since. Located in Gotham City, XYZ employs over 2,000 people and does all sorts of amazing things for the Gotham community.
