The page name is the page title that will appear on your page. Depending on how your design looks it could vary in position and/or style. Typically you should see it at the top of the page or marked through the navigation some how.
The URL slug is the page name as it will appear in the address bar of your browser. So for instance, a page called “About Us” could have the following URL slug:
The title for the page and the slug can be different.
When you first create a page, you’ll be asked to provide one. You can change it at any time just by visiting the page’s settings either from the Rilo Dashboard or the page editor.
