What E-E-A-T means — in brief
Google originally introduced E-E-A-T for its human quality raters: external reviewers who assess search results against quality criteria and whose feedback feeds into algorithm updates. The four dimensions are:
- Experience: Does the author have personal, hands-on experience with the topic? "I built this myself" beats "I read about it".
- Expertise: Does the author possess deep subject knowledge? Credentials, training, demonstrable specialization.
- Authoritativeness: Is the author recognized as an authority by others? External references, citations, "known for".
- Trustworthiness: Is the website transparent? Clear contact information, no misleading behavior, data protection.
The problem with SEO for a long time was this: these signals were optimized primarily for human reviewers. Pretty About pages, impressive bio texts, certificates as JPGs. What got overlooked: AI models read this differently.
How AI models assess authority
Unlike human quality raters, an AI does not read your About page "with understanding" — it processes tokens. That means: everything you want to communicate has to be encoded in a machine-readable way. A beautifully designed biography helps little if the underlying metadata is missing.
Concretely: when Claude or Perplexity handle a query and have to decide which source is trustworthy, they analyze primarily three machine-readable signals:
Signal 1: Schema.org Person markup
JSON-LD with @type: "Person" gives an AI structured information about the author — name, job title, employer, areas of expertise (knowsAbout), external profiles (sameAs). It is the direct, machine-readable way to say: "This person is an expert in X."
Signal 2: Consistent authorship across URLs
An AI does not assess just a single page — it assesses the domain. When Thomas Leonhardt consistently appears as the author on the About page, in every blog post header, in the footer, and in the Article schema, a coherent authority signal emerges. Inconsistency — sometimes "T. Leonhardt", sometimes "the author", sometimes no name at all — fragments the signal.
Signal 3: Linking to verifiable profiles
The sameAs property in Schema.org lets you connect the author with external, verified profiles: LinkedIn, GitHub, XING, a personal website. AI models can use these links to verify authorship and gauge expertise.
Schema.org Person — a complete example
The following JSON-LD snippet belongs on the /en/about/ page. It is the author's machine-readable identity card — fully filled in, with no field left out:
<script type="application/ld+json">

Explanation of the key fields:
- name: Exactly as on every other page — consistency is mandatory
- jobTitle: Specific and meaningful, not generic ("Managing Director")
- knowsAbout: Concrete topic areas — this is the direct pointer to expertise
- sameAs: LinkedIn and other verifiable profiles — third-party verification
- description: Prose with concrete figures (40+ projects, 6 years) — citable
Authorship at the article level
Every blog post needs two forms of authorship — one machine-readable and one humanly visible. Both are necessary, both must be consistent.
Machine-readable: Article schema with author property
{
"@type": "Article",
"author": {
"@type": "Person",
"name": "Thomas Leonhardt",
"url": "https://forgeproject.eu/en/about/"
}
}
The connection between Article and Person via the author property is the key. AI models that read the Article schema immediately understand: this content comes from an identifiable person with a machine-readable identity.
Humanly visible: byline with rel="author"
<a href="/en/about/" rel="author">Thomas Leonhardt</a>
<span>Founder & AI Orchestrator, FORGE</span>
The rel="author" attribute is a semantic HTML signal that tells search engines and AI crawlers: this link leads to the author's profile page. It reinforces the JSON-LD signal at the HTML level.
Consistency across the entire domain
The strongest GEO signal is domain-wide consistency. An AI does not assess a single article — it assesses all signals across a domain. In concrete terms that means:
- About page: Person schema + full biography + LinkedIn link
- Blog posts: Article schema with author property → points to the About page
- Contact page: same name, same role, same linking
- Footer: consistent brand name + author attribution where relevant
- Navigation: consistent "Founder" link to the same person
When an AI model crawls forgeproject.eu and finds the same coherent picture of Thomas Leonhardt as a GEO expert on every page, that is stronger than a hundred backlinks. Domain authority for AI does not come from external linking — it comes from internal consistency.
Domain consistency is to AI authority assessment what backlinks were to Google: the strongest off-page signal — except that now it is on-page.
Practical checklist: E-E-A-T for AI
- ☐ Schema.org
PersonJSON-LD present on the About page - ☐
knowsAboutarray filled with 4–6 concrete areas of expertise - ☐
sameAslinks to LinkedIn and other verified profiles - ☐ Article schema on every blog post with an
authorproperty - ☐ Visible byline on every article with
rel="author" - ☐ Author name consistent across all pages (same spelling)
- ☐
datePublishedandwordCountin every Article schema - ☐ Organization schema on the homepage with a
founderproperty
Eight points. Anyone who implements all eight has a machine-readable author identity that clearly signals to AI models: this person is an expert, this domain is a reliable source.
