What is E-E-A-T?

E-E-A-T: definition and meaning

E-E-A-T comes from the Search Quality Rater Guidelines, the manual external reviewers use to evaluate the quality of search results. The second “E,” for experience, was added in late 2022. It refers to whether an author knows a topic from firsthand involvement, such as a tradesperson who has actually carried out a repair.

Important: E-E-A-T is not a technical value and not a direct ranking factor. Google explains that its systems evaluate signals that fit helpful, trustworthy content. Of the four criteria, trustworthiness is considered the most important. The criteria describe an attitude more than a checklist: what should become visible is that real people with real knowledge stand behind a website.

How to show E-E-A-T on your website

The four criteria can be demonstrated concretely on a website. The more sensitive the topic, the more important it is: for pages on health, finance, or law (“Your Money or Your Life,” YMYL for short), Google applies particularly strict standards. The more of this the page itself demonstrates, the easier it is for raters and visitors to place it. Typical proof points:

• Experience: your own case studies, photos from real projects, hands-on practice
• Expertise: named authors with qualifications and a short bio
• Authoritativeness: mentions and links from trade media, associations, and partners
• Trustworthiness: a complete legal notice (Impressum), contact options, privacy policy, HTTPS, genuine reviews
• Sourced statements: references, dates, and visible updates

Real-world example: a tax firm improves its guides

A tax firm publishes guides on income tax, but anonymously and without dates. For a topic involving money, that is a weak signal. The firm adds author pages with qualifications and membership in the tax advisors’ chamber (Steuerberaterkammer), cites sources such as statutory texts, visibly updates articles, and shows references and contact details prominently.

These measures are not limited to Google: they also help visitors decide whether to trust the firm’s advice and arrange an initial consultation. That includes naming limits: where individual advice is needed, the text says so openly instead of making blanket statements.

Benefits, limitations, and common mistakes

Taking E-E-A-T seriously improves quality and credibility regardless of individual updates. Limitations: there is no E-E-A-T score that could be measured or optimized with a tool, and no plugins or badges that “produce” E-E-A-T. Trustworthiness also plays a role for AI answers, though providers do not disclose the exact criteria. Typical mistakes:

• Anonymous texts without author, date, and sources
• Invented author profiles or qualifications
• Mass-produced AI-generated content without expert review
• Bought or self-written reviews
• A missing or incomplete legal notice (Impressum)

What companies should look out for

Review your most important pages from a customer’s perspective: who writes this, where does the knowledge come from, and how do I reach the company? Rely on author pages, genuine references, and traceable updates. Structured data can make details such as author and organization machine-readable.
