Google introduced E-E-A-T — Experience, Expertise, Authoritativeness, and Trustworthiness — as a quality framework for human search quality raters. AI search engines apply the same principles algorithmically: they prefer content that demonstrates first-hand experience, domain expertise, recognized authority, and verifiable trust signals.
GEO Auditor's content engine measures E-E-A-T across your site, alongside content depth, topical authority, and the specific signals that distinguish human-written, citable content from generic AI-generated filler.
The four E-E-A-T dimensions
Experience
Does your content reflect direct, first-hand experience? AI engines increasingly distinguish between content written by someone who has done the thing versus someone summarizing what others have said about it.
The engine checks for:
- First-person language ("we tested…", "in our experience…", "I found that…")
- Specific examples drawn from real cases, not hypotheticals
- Case studies with concrete outcomes
- Original data or proprietary research
Content that scores poorly on experience tends to be written in a passive, generic third person ("it is generally recommended that…") with no grounding in direct observation.
Expertise
Expertise signals include author credentials, topic depth, and accurate use of domain terminology. The engine checks whether author credentials appear on the page or in schema (an author property on your Article schema linking to an Person entity with verifiable background), whether your content uses the correct technical vocabulary for the domain, and whether your coverage is substantive rather than surface-level.
Authoritativeness
Authoritativeness is largely about topical depth and coverage. The engine measures:
- Topical depth score: Does any single piece of content go deep enough to be a comprehensive reference on its topic?
- Topical breadth score: Does your site cover the full topic space of your domain, or only narrow slices?
- Pillar content: Do you have at least one long-form, authoritative piece that covers a core topic end-to-end?
- Topic clusters: Are your pages interlinked in ways that signal a coherent body of expertise on a subject?
Trustworthiness
Trust signals are the most concrete E-E-A-T dimension to check — and fix. The engine verifies:
- Contact information present and accessible
- Privacy policy present
- Terms of service present
- About page present (and substantive, not just a one-liner)
- Editorial guidelines present (especially relevant for publishers)
Sites missing these pages score significantly lower on trustworthiness, and AI engines treat them as lower-confidence sources for citation.
AI content signals
One of the more nuanced checks the content engine runs is detection of AI-generated content patterns. This isn't about penalizing AI-assisted writing — it's about identifying the generic, low-signal phrases that AI tools tend to produce and that AI search engines have learned to deprioritize.
Common patterns that suppress citability:
- "In today's fast-paced world…"
- "It's important to note that…"
- "As we can see…" / "It is worth mentioning…"
- Long introductory paragraphs that don't say anything
- Conclusions that just restate the introduction
The fix isn't to avoid AI writing tools — it's to edit the output aggressively, removing filler and replacing vague statements with specific, grounded claims.
Content metrics
The engine also measures structural content quality:
- Average word count: Longer content generally signals more depth. Pages under ~500 words rarely rank or get cited for competitive topics.
- Flesch reading ease: Extremely dense, academic writing can actually hurt citability — AI engines prefer content readable at roughly a 10th–12th grade level for most topics.
- Heading structure: Good heading structure (H1 → H2 → H3, no skipped levels) makes content easier to parse and extract from.
- Internal links per page: Pages with no internal links feel isolated; a reasonable internal link density helps crawlers discover related content.
How to improve your content score
Start with trust signals — they're the easiest wins. Make sure you have a real About page, visible contact information, a privacy policy, and terms. Then address AI content patterns: edit your key pages to remove filler and add specific, first-person, data-backed claims.
