What is schema.org markup?
Schema.org markup is structured data added to a webpage (via JSON-LD, Microdata, or RDFa) that declares what the page is about in a machine-readable way. Schema.org is a collaborative vocabulary maintained by Google, Microsoft, Yahoo, and Yandex. JSON-LD is the recommended format in 2026.

FAQ
Common questions about schema.org markup
Which schema types matter most in 2026?
FAQPage, Article, Organization, Person, BreadcrumbList, HowTo, Dataset, DefinedTerm, and Speakable carry the most extraction weight.
Does schema directly affect ranking?
Indirectly. Schema does not boost rank but it makes the page eligible for rich results and increases extraction probability inside AI Overviews and Perplexity.
Should schema be inline or external?
Inline JSON-LD inside a script tag is the recommended format. External schema files are not crawled by most engines.
Can incorrect schema hurt a site?
Yes. Schema that claims facts not present on the page (spammy FAQPage) can trigger manual penalties. Validate every schema in Google's Rich Results Test before deploy.
How does an LLM use schema?
Schema gives the LLM a structured handle on the page's entities and relationships. This shortens the reasoning path from query to citation.
