Structured data: the schema that earns AI citations

Structured data is the highest-ROI change for AI visibility. Here's which schema.org types matter, why, and how to deploy them without breaking anything.

If you do one technical thing for AI visibility, make it structured data. Across our scoring, structured-data coverage carries the most weight — and for good reason: it's the difference between a model inferring what you are and a model knowing.

What structured data actually does

Schema.org markup (delivered as JSON-LD) is a machine-readable layer that sits alongside your human-facing page. It states, unambiguously: this is an Organization named X, here is its product, here is the price, here is the answer to this question. Models don't have to parse marketing copy — they read the facts directly.

The types that matter

Not all schema is equal. For most brands, these earn their keep:

Deploy it safely

JSON-LD is invisible to users and low-risk to ship:

  1. Add a <script type="application/ld+json"> block to your page templates.
  2. Keep it consistent with the visible content — schema that contradicts the page can be ignored or penalized.
  3. Validate with Google's Rich Results Test and schema.org's validator before shipping.
  4. Don't fabricate — only mark up what's true on the page.

The compounding effect

Structured data also feeds traditional SEO (rich results), so the work pays off in both classic search and AI answers. It's the rare lever that moves everything at once.
