Third-Party Evidence

Evidence about a brand from sources it does not control.

Industry Term

Full explanation

Third-party evidence is evidence about a brand that comes from independent sources the brand does not control, such as press coverage, reviews, citations, or references. It is what turns a first-party claim into something a system, or a person, can verify.

Why this matters

This is where Earned Authority is actually built. It is slower and harder than publishing, which is precisely what makes it worth something.

Where this sits

Third-Party Evidence belongs to Content & Authority Strategy, one of the seven layers of the Aingworth Glossary. Where this thinking connects back to real work: the structures and evidence a brand builds to earn recognition, not just publish content.
