Canonical URL

A Canonical URL is the single, authoritative web address for a piece of content. In the context of AI visibility, the canonical URL of a company profile tells AI systems which version of the data to trust as the primary source.

Definition

A Canonical URL is designated via the <link rel='canonical'> HTML tag or the canonical property in JSON-LD.
It prevents duplicate content confusion when the same information exists at multiple URLs.
For company profiles, the canonical URL should point to the most complete, verified version.

Best practices

Set one canonical URL per company profile — all other versions should reference it.
Use absolute URLs (https://domain.com/path), never relative paths.
Include the canonical URL in JSON-LD, HTML meta tags, and HTTP headers consistently.
AI crawlers use canonical URLs to deduplicate and prioritize information sources.
