E-E-A-T
Also called EEAT, E-A-T, Experience Expertise Authoritativeness Trustworthiness.
E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness — Google's framework for evaluating content quality, and the authority signals that heavily influence AI engine citation decisions.
What it means
E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) is the quality framework Google's Search Quality Raters use to evaluate whether content is genuinely helpful and reliable. While it's not a direct algorithmic ranking factor — there's no 'E-E-A-T score' Google calculates — it describes precisely the signals Google's algorithms are designed to detect and reward.
The four dimensions are distinct in practice. Experience means the content author has first-hand, real-world experience with the topic — a review written by someone who actually used the product. Expertise means demonstrable knowledge: credentials, professional background, specialized training. Authoritativeness means recognition by others in the field — external citations, editorial coverage, mentions in trusted sources. Trustworthiness is the most foundational dimension: accurate facts, cited sources, transparent authorship, and a site that behaves honestly.
For AI engine optimization, E-E-A-T is particularly consequential. LLMs are trained to preferentially cite authoritative, trustworthy sources. A site with strong E-E-A-T signals — author bylines with linked credentials, cited sources, original research, real About pages with verifiable entity information — is structurally more likely to be weighted as a trusted source in both LLM training data and real-time retrieval systems.
Key takeaways
- E-E-A-T applies most strictly to YMYL content: health, finance, legal, and safety topics
- Author entity pages with credentials and professional profiles are a practical E-E-A-T signal
- Trustworthiness is the most foundational dimension — it's the prerequisite for the others
- Original research and first-hand experience are the highest-value E-E-A-T demonstrations
When it matters
E-E-A-T matters most for YMYL (Your Money or Your Life) content, where low-quality information could cause real harm. It increasingly matters for all content as AI engines use authority signals to decide what to cite — making E-E-A-T an AI SEO concern, not just a Google one.
