What each component means
Experience refers to first-hand, practical knowledge of the topic. A page written by someone who has actually implemented what they describe scores higher on Experience than one written from secondary research alone.
Expertise refers to the depth of knowledge demonstrated in the content. Technical accuracy, completeness, and the ability to answer follow-up questions are signals of expertise.
Authoritativeness refers to the recognition of the author or site within its field. External citations, links from credible sources, mentions in industry publications, and consistent presence in a topic area all contribute to authority.
Trustworthiness refers to the reliability and transparency of the content and its source. Clear authorship, accurate dates, verifiable claims, editorial policies, and secure infrastructure all contribute to trustworthiness.
E-E-A-T is not a ranking factor
Google has clarified that E-E-A-T is not a direct algorithmic ranking signal. Search Quality Raters use it to evaluate the quality of search results — their ratings are used to improve ranking systems, not to rank individual pages directly.
That said, the properties described by E-E-A-T align closely with what Google's systems reward: helpful, accurate, well-attributed content from identifiable sources.
E-E-A-T and AI Search
For AI Search systems such as ChatGPT Search, Perplexity, and Google AI Overviews, E-E-A-T signals remain useful — not as a confirmed citation factor, but as a practical framework.
A page with a named author, verifiable credentials, current sources, transparent dates, and clear editorial responsibility is easier for an AI system to evaluate as a reliable source than anonymous, unsupported content.
How to improve E-E-A-T signals
- Add named authors with linked bios to every article
- Include author credentials, years of experience, and links to external presence
- Reference named sources, tools, and data — not vague "studies show"
- Add a clear editorial note explaining the basis for claims
- Keep publication and modification dates visible and accurate
- Build external presence: directory profiles, industry citations, partner mentions
