# AEO schema markup: the JSON-LD types AI engines actually parse

> Not all schema is read equally. The JSON-LD types AI engines parse most heavily for AEO — and the implementation patterns that work.

If your buyers are asking ChatGPT, Claude, Perplexity, or Gemini for recommendations in your category, the question of **AEO schema** is no longer optional — it is the new top of funnel. This guide is a working playbook, not a theory piece.

We wrote this for marketing leaders, founders, and growth teams who want to be cited by ChatGPT, Claude, Perplexity, and Gemini for the queries that actually move pipeline.

## The JSON-LD types worth shipping

**Organization** — sitewide identity. Ship once.
**Article / BlogPosting** — every long-form post.
**FAQPage** — every page with Q&As.
**HowTo** — every step-by-step guide.
**Product** — every product page.
**BreadcrumbList** — every nested page.
**Person** — every author bio.
**Review / AggregateRating** — only with real, verifiable reviews.

## Schema mistakes that hurt AEO

1. FAQ schema with no visible Q&A on the page (penalised).
2. Review schema for fake or unverified reviews (penalised hard).
3. Multiple conflicting Organization records.
4. Missing `mainEntityOfPage` on Article schema.

## How to validate

Use Google's Rich Results Test for surface eligibility, and Schema.org's validator for spec compliance. For LLMs specifically, run your page through a fetch-and-parse test — if a plain text fetch produces a clean version of your content, the model can use it.

## Frequently asked

### Is microdata still useful?

JSON-LD is preferred by every major engine. Stick to JSON-LD.

### Does schema directly improve LLM citations?

Yes — measurably for Perplexity and Gemini, indirectly for ChatGPT and Claude.
