Trust signals are the properties that make content easy to trust, verify and attribute — named authors, verifiable credentials, current sources, transparent dates and clear editorial responsibility.
Why it matters
E-E-A-T — Experience, Expertise, Authoritativeness and Trustworthiness — comes from Google's Search Quality Rater Guidelines. It should not be described as a direct ranking factor or a confirmed AI citation signal. But it is a useful framework for evaluating whether content is easy to trust, verify and attribute.
For AI Search, the same logic applies: a page with a named author, clear editorial responsibility, current sources, transparent dates and verifiable expertise is easier to evaluate as a reliable source than anonymous, unsupported content — for users and systems alike.
The four components
Experience
First-hand, practical knowledge of the topic. Content written by someone who has actually implemented what they describe scores higher than secondary research alone. Implementation examples, screenshots from real audits and documented decisions all demonstrate experience.
Expertise
Depth of knowledge demonstrated in the content. Technical accuracy, completeness and the ability to answer follow-up questions are signals of expertise. Named authors with documented credentials, years of experience and published work demonstrate expertise.
Authoritativeness
Recognition within the field. External citations, links from credible sources, mentions in industry publications and consistent presence in a topic area all contribute to authority. A brand cited by other sources is more authoritative than one that only self-publishes.
Trustworthiness
Reliability and transparency of content and source. Clear authorship, accurate dates, verifiable claims, editorial policies and secure infrastructure all contribute. Anonymous content with no sources and no dates signals low trustworthiness.
Original experience — the hardest signal to copy
AI systems do not need another generic explanation of the same topic. They need sources that add something specific: implementation details, tested workflows, real examples, data or expert interpretation. Definitions can be rewritten by anyone. Original experience cannot.
