What is E-E-A-T and how to apply it to be cited by AIs?
The four credibility dimensions that determine whether a source is cited by Google AI Overview and ChatGPT
E-E-A-T is the set of four dimensions Google uses to evaluate the credibility of content: Experience, Expertise, Authoritativeness, and Trustworthiness. For AIO, these signals determine whether an AI system will trust the source enough to cite it. An article without identified authorship, published on a site with no editorial history, has systematically lower probability of citation than the same content published by a source with verifiable credentials.
Experience: evidence of real firsthand knowledge
The first E was added by Google in 2022 and represents evidence that the author had direct contact with the topic — not just read about it. For AIs, this signal is captured via:
- Concrete cases narrated from a firsthand perspective
- Real data, not extracted from generic sources
- Operational details only someone who has practiced would know
Practical example: an article about apartment renovation written by an architect who describes a real project — with floor plans, actual budgets, and decisions made during the process — carries far more experience signal than a generic "10 renovation tips" article. The same principle applies to an accountant describing a real tax planning case, or an attorney narrating the behind-the-scenes of a contract negotiation.
Expertise: declared and verifiable credentials
Expertise is declared via Schema.org author with an identified Person, jobTitle, and sameAs pointing to verifiable professional profiles (LinkedIn, professional registries, institutional pages). For regulated sectors — healthcare, law, finance — the absence of an identified credential is a strong negative signal.
How to apply by sector:
- Health blogs: author must have a medical license (MD, RD, etc.) with a verifiable link
- Legal content: attorney with bar registration declared and public profile
- Finance: CFP, CFA, CPA identified and linked
- Education: professor with institutional or academic profile
An article about infant nutrition signed by "Editorial Team" carries less weight than the same article signed by a registered dietitian with credentials and a professional profile link.
Authoritativeness: external recognition
Authority is built through external citations, backlinks from relevant domains in the same segment, and mentions of the brand in other reliable sources. For generative AIs, a site referenced by other industry sites has a stronger authority signal than an isolated site, even with good content.
Strategies to build authority:
- Retail: having products or analyses cited by specialized consumer portals
- Healthcare: content linked by reference medical portals and hospitals
- Technology: being mentioned in industry publications, events, and relevant forums
- Education: having content referenced by other educational institutions
Trustworthiness: technical signals and editorial transparency
Trustworthiness is verified through technical and editorial transparency signals:
- Active HTTPS on all pages
- "About" page with company and identified team information
- Accessible privacy policy and terms of use
- Explicit contact information (physical address, phone, email)
- Schema.org
Organizationwith complete information - Consistency between what the Schema declares and what the page visually displays
Inconsistencies that destroy trustworthiness: Schema.org with a 2021 publication date for an "updated" 2025 article; author declared in Schema different from the author visible on the page; Schema address different from the footer address.
How to apply E-E-A-T across different segments
For a dental clinic: - Articles signed by dentists with license numbers and specialty descriptions - Treatment case studies (with patient authorization and anonymization) - Team page with photos, degrees, and professional registration numbers for each dentist
For a logistics company: - Operational content written by directors with sector track records - Real data on SLA, delivery times, and damage rates from the company's own operations - Mentions in supply chain portals and industry associations
For a language school: - Articles on methodology signed by pedagogical coordinators with linguistics degrees - Testimonials with real student progress data - Certifications and partnerships with international institutions declared in Schema
