Author Schema
Author Schema is structured data markup using the Person type from Schema.org that identifies the human author of a piece of content, providing search engines with machine-readable information about their name, credentials, affiliations, social profiles, and other published works. It is typically implemented in JSON-LD in the page head or body of article and blog pages.
Google uses Author Schema to build its understanding of an author as a named entity, connecting them to other content they have published and third-party mentions of their expertise. This is a key mechanism for establishing author-level E-E-A-T, particularly for YMYL topics where the credentials of the person writing the content are directly relevant to its trustworthiness.
Why it matters for SEO
Author Schema is a primary technical mechanism for communicating author credentials and expertise to search engines, supporting E-E-A-T signals that Google uses to evaluate content quality. Implementing it correctly — with verifiable credentials and consistent sameAs references — helps Google connect authorship to real-world authority and treat the content accordingly.
