What Does E-E-A-T Stand For?
E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness. It's a concept from Google's Quality Rater Guidelines — the handbook human quality raters use to evaluate the quality of search results.
E-E-A-T is not a single algorithm factor with a score. It's a framework that summarizes many different signals. Google uses E-E-A-T to assess whether a page is trustworthy enough to be displayed for a specific search query.
E-E-A-T is Google's framework for content quality. The additional E for Experience was added in late 2022 and emphasizes that first-hand experience is its own quality factor.
The Four Components
Experience
The newest element in E-E-A-T. Google evaluates whether the author has actual experience with the topic. A travel blogger writing about a hotel they stayed at has more Experience than someone who only knows the hotel from descriptions.
For your website, this means: Show personal experience. Document your own experiments, share results and learnings, use your own screenshots and data. That's why our experiment article "From 0 to 10,000 Impressions" is so valuable — it shows real experience.
Expertise
Does the author have the necessary expertise on the topic? For medical or legal topics, Google expects formal qualifications. For other topics — like SEO or AIO — demonstrated knowledge through comprehensive, accurate content is sufficient.
Demonstrate expertise through: In-depth, accurate content. Correctly used technical terms. References to current developments and data. A clear author biography describing your qualifications.
Authoritativeness
Is the author or website perceived as an authority in their topic area? Authority comes through reputation: Backlinks from trustworthy websites, mentions in the industry, citations by other experts.
For a new website, you build authority step by step: Through consistent, high-quality content, through presence on relevant platforms, and through the topical depth of your content.
Trustworthiness
Trust is, according to Google, the most important component. Can the page be trusted? Signals for trustworthiness: HTTPS, legal notice and privacy policy, transparent author information, correct facts, and the absence of manipulative or misleading content.
E-E-A-T and AIO
AI models use similar trust signals as Google when selecting sources. Websites that meet E-E-A-T criteria — fact-rich content, demonstrated expertise, authority through topical depth — are more frequently cited as sources in AI answers.
The E for Experience is particularly relevant here: AI models cannot have their own experiences. Content based on real experience is especially valuable for AI systems because it's unique and non-replicable.
