Schema.org Markup
Last updated
Structured data added to web pages using the Schema.org vocabulary to help search engines and LLMs understand content semantics.
Full definition
Schema.org markup (commonly implemented as JSON-LD) is structured data that explicitly labels content types and relationships on a web page. Examples: marking a page as a Review with itemReviewed pointing to a SoftwareApplication, declaring an FAQ section as a FAQPage with Question/Answer pairs, identifying authors with Person nodes linked via @id. In 2026 schema markup is critical for both traditional SEO (rich snippets, knowledge panels) and AEO (LLMs use schemas to build entity graphs and verify content claims). Best practice: use @graph with stable @id URIs to connect entities (Organization, Person, WebSite, Article) into a coherent graph.
Examples
- ·Adding FAQPage schema to every article to increase chance of rich snippet appearance in Google.
- ·Using SoftwareApplication + AggregateRating schemas on product review pages to show star ratings in SERPs.
- ·Linking Person (author) and Organization (publisher) via @id across all pages to help LLMs identify the entity behind the content.
