Structured data, Schema.org markup expressed as JSON-LD, is read by both search-engine crawlers and AI retrievers to categorize your business unambiguously. For GEO, a handful of schema types do most of the work. Here's where to focus.

1. Organization, your entity anchor

The single most important schema. It defines who you are with a stable @id, your name, description, what you knowsAbout, your sameAs social profiles, and your offerings. Every other schema on your site should reference this organization via its @id, so the AI builds one coherent entity rather than scattered fragments.

2. FAQPage, the highest-citation type

FAQ markup is consistently the easiest content for an AI to lift directly into an answer, because each question maps to a query and each answer is a self-contained, quotable response. Put an FAQPage on your homepage and key landing pages, answering the literal questions buyers ask assistants: "Who is X?", "What does X do?", "How much does X cost?"

3. Product, for anything you sell

If you have a catalog, each product page should carry Product schema with a name, identifier (SKU, GTIN, or in technical fields, things like a CAS number), key properties, and an offer that references your Organization as the seller. This lets an AI attribute specific items to you with confidence.

A word of caution: only emit claims you can stand behind. Don't fabricate stock levels or prices in markup you don't maintain, an AI quoting a false "in stock" claim is worse than no claim at all.

4. Article / BlogPosting, for expertise

Every blog post should carry Article or BlogPosting schema with a headline, publish date, author, and a publisher reference back to your Organization. This is how AI systems attribute expert content to you, and expertise is a major input into whether you get recommended.

The rule that ties it together

Structured data must never contradict your visible content. The schema and the prose should be generated from the same facts. When they agree, you give the AI a clean, reinforcing signal. When they conflict, you give it a reason to distrust you, and trust is the whole game in GEO.
