Article (schema.org)
Article, along with its variants NewsArticle and BlogPosting, is a schema.org type that marks up editorial content such as blog articles in machine-readable form, with details of the author, publication date, image and core topic.
In practice
A fully marked-up author reference including Person schema visibly supports E-E-A-T, because it lets search engines and AI systems attribute content to a real, traceable expert rather than to anonymous text.
