Schema.org Schema.org / Structured Data Machine-readable meaning for every page.

Schema.org is the shared vocabulary search and answer engines use to read structured data from web pages. Marking up an article with BlogPosting, FAQPage, BreadcrumbList, and DefinedTerm tells engines what each block means — which is what makes featured snippets, AI Overviews, and rich results possible.

How Schema.org differs from AEO, SEO, Featured Snippet

Semantic HTML (article, section, dl) tells the browser what something is structurally. Schema.org goes further — it tells engines what something means as an entity (Article, Person, Product, Recipe, FAQPage).

Frequently asked questions about Schema.org

What is Schema.org?

A shared vocabulary, maintained by Google, Microsoft, Yahoo, and Yandex, for marking up structured data on web pages so search and answer engines can read meaning, not just text.

Which schemas matter most for AEO and GEO?

BlogPosting (or Article), FAQPage, BreadcrumbList, and DefinedTerm. HowTo, QAPage, and Speakable apply when the outline calls for them.

Does schema markup still matter in 2026?

Yes. AI Overviews, featured snippets, and Perplexity all read structured data. Schema doesn't guarantee a rich result, but missing schema rules a page out.
