Article, NewsArticle, and BlogPosting Schema: Establishing E-E-A-T and Rich Snippets

Master editorial structured data. Learn the differences between Article, NewsArticle, and TechArticle, and how author sameAs links strengthen Google E-E-A-T.

Published on August 25, 2026Updated August 25, 2026

With Google’s relentless focus on E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) and the rise of AI-generated content, clearly establishing who wrote an article and when it was updated is vital for organic search rankings.

By implementing Article, NewsArticle, BlogPosting, or TechArticle schema, publishers provide explicit machine-readable metadata that feeds into Google Knowledge Graphs, Top Stories carousels, and AI citation engines.

This guide breaks down the required properties, author entity linking, and date management for editorial schema.

Why Author sameAs Links are Essential for E-E-A-T

Google’s Knowledge Graph builds entity profiles for human subject matter experts.

By including verified external profile URLs (Twitter, LinkedIn, GitHub, ORCID, Wikipedia) in the author’s sameAs array, you explicitly link the article’s author to an established real-world identity, verifying domain expertise and elevating content trust.

Date Synchronization Rules

• datePublished: The exact date/time the article was first made public.
• dateModified: Update this timestamp whenever meaningful content edits, corrections, or expansions occur. Google uses dateModified to display the “Updated [Date]” badge in search results.
• Ensure on-page visible timestamps match the JSON-LD timestamps exactly to prevent manual action penalties.
