4.3 Entity & Knowledge Graph ✦MediumInferred
Author entity not corroborated externally
An author who exists only on your site is hard for Google to trust as a real expert. External corroboration, publications, profiles, mentions, turns a byline into a recognised entity.
What it is
Author exists only on-site.
Why it matters
Author authority can’t be cross-verified.
How to fix it
Build genuine external author presence.
How to find it on your site
- Check whether the author has authoritative external presence.
- Build or surface profiles and contributions elsewhere.
- Link to them via sameAs from the author schema.
- Keep the identity consistent.
Cross-reference to ranking and citation factors
External corroboration is what elevates an author from a name to a trusted entity. Site-only authors lack it.
