Identify locations

Every place needs a unique identity, so people can associate what they’re perceiving at that moment with that name. Identities also refer to a specific location to others or in their own memory.

In the real world, streets have names and houses have numbers, which helps people find and refer to them clearly. In the US, grocery store aisles have numbers. These numbers help clerks refer customers to a specific place when they inquire about an item (e.g. “Bread is on aisle 5” rather than “Bread is over there.”)

In the digital world, pages have titles, which helps users remember and refer to them. Pages also have URLs, which allow them to be accessed from anywhere and referred to unambiguously.
