Most sites have either no schema, the wrong types, or a pile of disconnected JSON-LD blocks that read as noise. AI engines read schema to decide whether to trust and cite you. This is the minimum graph that earns that trust, with copy-paste patterns, and the four mistakes that void the whole thing.

## Why AI engines care about schema

An AI engine deciding whether to cite your page has a verification problem. Prose is cheap to fake. Schema gives the engine machine-readable claims it can cross-check: this Organization, founded by this Person, who has these credentials, published this Article on this date, and the same Person exists at these LinkedIn and verification URLs.

That cross-checkable chain is the cheapest trust signal in GEO. A few hours of one-time work, no budget line, and most competitors still have not done it.

## The 2026 minimum: three connected types

Every page should ship at least these three types, connected into one graph:

1. **Organization.** Name, logo, founder, address, and the `sameAs` array pointing at LinkedIn, Crunchbase, and directory profiles. Your entity anchor.
2. **Person.** The author. Name, `jobTitle`, `knowsAbout` topics, `sameAs` links to public profiles. Anonymous content gets cited less.
3. **Article** (or Service on service pages). Headline, description, dates, and critically: `author` and `publisher` pointing at the Person and Organization.

The word doing the work is *connected*. Three floating JSON-LD blocks that never reference each other are noise.

## Stable @id references: the part everyone skips

Give your Organization the id `https://yoursite.com/#org` and your founder `https://yoursite.com/#founder`, then have every Article on every page point at those same ids via `author: {"@id": ...}` and `publisher: {"@id": ...}`.

When every page references the same ids, the engine assembles your whole site into one entity graph instead of treating each page as a stranger. Forty pages each independently claiming "we are an SEO agency" is forty weak signals. Forty pages all pointing at one Organization node is one strong one.

## The two types that earn their keep: FAQPage and HowTo

**FAQPage** belongs on any page with real questions and real answers. Each Q&A pair becomes an individually citable unit. Only mark up questions people actually ask (mine them from People Also Ask, sales calls, GSC query data). Fabricated FAQ blocks read as low quality.

**HowTo** belongs on procedural content. Each step becomes a citable unit with a position, name, and text.

## The four mistakes that void the graph

1. **Disconnected blocks.** Five JSON-LD scripts, none referencing the others. Fix: one `@graph` array, stable `@id` references.
2. **Fabricated reviews.** Review/AggregateRating markup with no real reviews behind it. Converts schema from a trust signal into a deception signal, plus manual-action risk in Google. Real reviews only, named reviewers.
3. **FAQ stuffing.** Twenty keyword-variant questions nobody asks.
4. **Schema that contradicts the page.** Markup claiming an author the page never shows, dates that disagree with the byline. Engines cross-check rendered content against markup; contradiction reads as deception.

## The validation loop

After any schema change: Google Rich Results Test, the schema.org validator, then fetch the page with an AI-bot user agent (GPTBot, ClaudeBot) and confirm the JSON-LD is in the served HTML, not injected client-side by JavaScript the bot never executes. Client-side-injected schema is invisible to most AI crawlers.

## Implementation order

1. Day one: build the core graph (Organization + founder Person) once as a shared block, add to every page. 2-4 hours.
2. Day one: Article/Service markup per page template pointing at the core ids. ~2 hours templated.
3. Week one: FAQPage on the five pages with real question traffic (check GSC for question-shaped queries).
4. Week one: HowTo on procedural content. BreadcrumbList sitewide.
5. Ongoing: real Review markup as real reviews arrive. Keep dateModified honest.

Roughly one focused day for a small site. Permanently upgrades how every engine reads you.

## How this fits the bigger GEO picture

Schema is one of the eight citation signals. It pairs with chunk-level citability (schema tells the engine who you are; chunking gives it something quotable). Full picture: the How to Get Cited by ChatGPT playbook. The visibility measurement side: the GEO Prompt Research playbook.
