Schema is not just about rich results anymore. LLMs use structured data to resolve entities and validate claims. Here is the schema stack that produces measurable AI citation lift.
The five schema types worth shipping
Organization, Article, Product, FAQ and Breadcrumb do 90% of the work. Everything else is optional.
Common mistakes
Marking up content that isn't visible on the page, duplicating schema across templates, and leaving invalid dates are the top three violations we see in audits.
Frequently asked questions
Does more schema always help?
No. Only mark up what is visible on the page and only use schema types Google supports for the intended enhancement.
Do LLMs actually read schema?
Yes. Structured data is one of the cleanest inputs for entity resolution, which is why sameAs and Organization markup move the needle.
