Structured Data for Entities

About 11 minutesPrerequisite: Lesson 5.3

After this lesson you candecide where Organization and Person markup truthfully fit, wire sameAs correctly, validate your markup, and state plainly what structured data does not do.

Structured data is a vocabulary (schema.org is the common one) for stating facts about a page and its entities in a machine-readable format. Used truthfully, it removes ambiguity: it says which entity this site represents, which URLs belong to it, who wrote this page. Used as a charm, it wastes an afternoon.

What it does, honestly

Disambiguation: an Organization block with your canonical name, URL and sameAs profile links states "this site is that entity".
Relationships: Person markup on author pages ties articles to people; publisher blocks tie pages to the organisation.
Classic search features: eligible rich results (reviews for products, event listings, course listings where genuinely applicable) depend on matching markup.
Maintenance of meaning: one authoritative JSON block is easier to keep accurate than prose scattered across footers.

What it does not do

Three myths to kill on sight. It does not cause AI citations: Google states its AI features require no special schema, and no platform documents any markup that produces citations. It does not substitute for corroboration: declaring "award-winning" in JSON persuades nobody, because markup is still self-description. And it does not override your visible content: markup that contradicts the page is worse than no markup. Structured data states what is already true, cleanly. That is the whole job.

DefinitionsameAs is a property that lists URLs of the same entity elsewhere: profiles, listings, the entity's other official pages. It is the wiring that connects your site's entity statement to the wider web, so point it only at URLs that genuinely represent you.

The honest minimum

Site type	Truthful minimum	Only if factually true
Business site	Organization with name, url, logo, sameAs	address, contactPoint, founder
Publication	Organization + Person on author pages	alumniOf, award (verifiable ones)
Personal site	Person with name, url, sameAs	jobTitle, worksFor
This course site	Organization, WebSite, WebPage, Course	instructor, if a real named instructor exists

Validation is free: Google's Rich Results Test and Search Console's reports flag syntax errors and eligibility. Validate when you add markup and re-validate after any site template change, which is when silent breakage happens.

Worked example: one Organization block, annotated

State @id once ("https://example.com/#org") and reference it from pages instead of restating the entity.
name: the canonical trading name from your lesson 5.1 record, exactly as written there.
sameAs: your real profiles only. Three genuine URLs beat ten including dead accounts.
description: the one-sentence identity from the canonical record, not this quarter's campaign line.
Re-check every six months: dead profile links in sameAs are the most common rot.

Workbench 5.4

Check whether your site already carries Organization or Person markup (view source, search "application/ld+json").
If it exists, verify every field against your canonical record and delete anything stale or untrue.
If it does not, add the honest minimum for your site type and validate it.
Add a six-month calendar note to re-validate, tied to your entity-consistency re-check from lesson 5.1.

Self-check

Does adding Organization schema make an AI system cite you?

No. Google says its AI features need no special schema, and markup is self-description, not corroboration. It clarifies who you are; citation is earned through content and third-party evidence.

What belongs in sameAs?

URLs that genuinely represent the same entity: real profiles, official listings, the entity's other official pages. Quality over quantity; dead or tangential links dilute the statement.

When is markup worse than nothing?

When it contradicts the visible page or states things that are not true. Systems cross-check markup against content, and inconsistency reads as either error or manipulation.

Key principleStructured data states what is already true, cleanly: it clarifies identity, it never substitutes for earning it.
