What is schema markup, and why does AI care?
Schema markup is structured data — usually written as JSON-LD in your page’s <head> — that labels your content for machines. Instead of an engine guessing that a block is an author, a price or a question, schema states it explicitly. That clarity helps AI engines resolve your entity and trust your answers, which is why marked-up content shows materially higher AI visibility.
The schema types that matter most for AEO
| Type | Use it on | Why it helps |
|---|---|---|
| Article | Blog posts, guides | Author, date, topic |
| FAQPage | Pages with Q&A | Direct answer extraction |
| Person / Organization | About, homepage | Entity resolution |
| Service | Service / pillar pages | What you offer & where |
| BreadcrumbList | All deep pages | Site structure |
A minimal FAQPage example
Drop this in your page head and adapt the questions to ones your buyers actually ask:
<script type="application/ld+json">
{
"@context":"https://schema.org",
"@type":"FAQPage",
"mainEntity":[{
"@type":"Question",
"name":"What is AEO?",
"acceptedAnswer":{
"@type":"Answer",
"text":"AEO structures content so AI engines cite it as the answer."
}
}]
}
</script>How to add and validate it
Place each block as JSON-LD in the page head, keep it accurate to what is visible on the page, and validate with Google’s Rich Results Test or the Schema.org validator. Then make sure the rest of your content is structured to get cited and your llms.txt is in place — schema is one pillar of a full AEO system, not a magic switch.
Frequently asked questions
Does schema markup help with AI citations?
Yes. Structured data lets AI and search engines understand your content and resolve your entity, and marked-up pages consistently show higher AI visibility. It works best combined with clear on-page answers and authority signals.
Which schema type should I start with?
Start with Article and FAQPage on your content, plus Person or Organization on your homepage and about page. Those cover authorship, direct-answer extraction and entity resolution, the signals AI engines lean on most.
Will schema alone get me cited by AI?
No. Schema is necessary but not sufficient. It helps engines understand you, but citations still require extractable answers, statistics, expert authority and freshness. Treat schema as one layer of a complete AEO system.
