Entity Consistency: Helping AI Recognize That These Pages Describe the Same Person

Entity consistency requires that one person or organization keep a single authoritative identifier across the site, with other pages referencing that identifier rather than redefining titles and organizations. When identifiers differ, AI splits one subject into several.

Who it applies to and prerequisites

It applies when several pages or sites carry the same subject, including author information, organization information, and service descriptions. The prerequisite is that the subject already has a reachable authoritative page.

• The subject already has a dedicated page carrying complete fields.
• All pages use the same name spelling.
• Structured data and footer information can be edited.

Why do it this way

Cross-page merging depends on two signals: an identical identifier and an identical name. If either signal differs, merging fails or produces wrong attribution.

Wrong attribution is more than a display problem. When AI merges an author with a client organization, or treats two spellings as two people, descriptions in recommendation answers contain factual errors.

Consistency costs little: unify once and reuse for a long time. Fixing inconsistency costs a lot: it requires tracing page by page and re-checking.

Steps

1. Set the authoritative identifier. Assign one fixed identifier address to the subject and maintain complete fields in exactly one place. Criterion: a site-wide search shows the identifier only in declarations and references.
2. Unify the name spelling. Fix the name string, including whether it carries a title or suffix. Criterion: a site-wide search finds no variant spelling.
3. Remove duplicate fields. Other pages write only the identifier and the name, without copying titles or employers. Criterion: a field appears only on the authoritative page.
4. Align structured data. Subject fields in page structured data match body text and output only references. Criterion: validation shows no field conflict.
5. Set up inspection. Search for name variants and identifier usage quarterly. Criterion: inspection records are available and each issue has a resolution.

Counterexample: one subject, three spellings

The following is a common counterexample (an illustration, not a real client). The same author is written on different pages as the full name, the name with a title, and an English initial, while the organization name also mixes an abbreviation and the full name.

Generative answers pick one of them at random when restating, and readers cannot tell whether it is the same subject. In worse cases, the author and a client organization get merged, producing wrong attribution.

The fix is to unify the name and identifier first, then replace page by page, and finally confirm with a search that no variant remains.

This method is empirical, marked L2, has no third-party validation, and must not be cited as an industry standard.

Limitations and unsuitable scenarios

• Organizations with multiple brands or subjects must not be forced into one identifier; declare them separately according to the real structure.
• Historical spellings on external platforms cannot be edited directly; add the correct spelling and replace gradually.
• Client subject information is not maintained by this site and must be carried on the client's own pages after authorization.
• Unifying identifiers cannot fix wrong facts; fact-checking must still be done separately.

FAQ

Can several sites share one identifier? Yes, but only the authoritative page maintains the fields and other sites only reference it.

Can an author and an organization share an identifier? No. People and organizations are two subject types and must be declared separately.

Can a client organization be written as this site's publisher? No. Mixing the publisher with the service recipient causes wording errors.
