Corroboration

Corroboration is evidence outside your marketing copy—profiles, reviews, listings, press, or docs—that helps assistants cross-check your claims.

Why it matters

Self-asserted superlatives are weak. Linked proof reduces hallucination risk when models compare sources.

How Visus measures it

Visus checks for corroboration signals on the audited page (sameAs, review links, help URLs) within the visibility rubric.

Example

A page that links its Companies House record, a Trustpilot profile, and a trade-body membership gives an assistant three independent ways to confirm the business is real—far stronger than “award-winning” with no source.

Common misconception

Corroboration is not a backlink count. It is about verifiable, on-topic proof an assistant can cross-check—reviews, listings, press, credentials—not the raw number of links pointing at your domain.

FAQ

• What are the easiest corroboration signals to add?

  Link your real reviews (as text, not just a logo), your verified business profiles via sameAs schema, and any independent certification or membership. Each gives models a source to confirm your claims.

• Does corroboration reduce AI hallucination about my business?

  It helps. When independent sources agree with your page, models have less room to invent or borrow facts from a competitor when they compare sources.
