Canonical URL

The one official address for a page.

Definition

The preferred URL for a piece of content when it is reachable at several addresses.

Craft convention. True because the industry converged on it. Breaking it costs familiarity, not correctness.

In plain language

The one official address for a page.

Example

Declaring a canonical URL when the same article is reachable through two category paths.

Each link says what the connection is, so you can tell a principle from an alternative from a thing people mix this up with.
