E-E-A-T Signals — audit + strengthen (Astro)
Make a page demonstrate Experience, Expertise, Authoritativeness and Trust to
both humans and AI engines — and verify it with a runnable auditor. Trust is the
load-bearing pillar; first-hand Experience is the asymmetric edge a real operator
has over a larger competitor.
Scope boundary (read before doing anything)
This skill owns the human-visible + crawler-visible signal layer. It does not:
- generate JSON-LD → that is schema-entity-graph (
schema-skill);
- validate JSON-LD /
@id wiring / rich-result eligibility → that is schema-audit;
- rewrite copy tone/voice → that is humanise-copy;
- do build/perf/a11y/Lighthouse → that is astro-audit (plug EEAT in as a compliance check).
See BOUNDARIES.md for the exact seams. When a signal also has a
schema form (author, reviews, sameAs, knowsAbout), check the visible side here
and leave the markup to the schema skills. Never duplicate their rules.
The auditor (runnable)
npm install
npm test # 41 unit + integration tests
npm run audit -- --dir ./dist --market hu --robots ./dist/robots.txt
npm run audit -- --html ./dist/index.html --market uk
--market = uk | hu | generic. Exit code is 1 if any check is fail, else
0, so it can gate a deploy. The auditor only reports — it never edits the site.
Statuses: pass / warn / fail / not_found (not-applicable, non-blocking). Gaps
are surfaced as observed_differences, never as "opportunities".
DO — signals to place (then verify)
- Author: visible named byline on articles + a bio with specific credentials
(years in trade, dates, certifications, real numbers) — not adjectives. (
author.*)
- Experience: first-hand proof — case study, before/after, captioned own photos,
first-person job description, original data. The one thing a competitor can't fake.
- Trust pages: about, contact, privacy always; terms; returns/refund/shipping
for product pages. (
trust-page.*)
- Business trust: visible phone, postal address, and company registration
(UK Companies House number / HU cégjegyzékszám + adószám), plus recognised
trust-marks. (
business.*)
- GEO / AI: answer-first opening (~40–360 chars) + numeric facts; allow AI
retrieval crawlers in robots.txt. (
geo.*, ai-crawler.*)

references/ai-visibility.md.
DON'T — forbidden (these fail the audit or the review)
- Fake authors, AI-generated headshots, invented credentials, exaggerated experience.
- Scaled/mass-generated content; paraphrase-only pages with no added first-hand value.
- Fake/incentivised reviews; self-serving review markup (defer detail to schema-audit).
- Fabricated stats/case studies; claims of expertise with nothing demonstrated.
- Blocking AI retrieval bots while expecting AI visibility.
- Speakable schema on a non-news site; schema that doesn't match visible content.
Full detail: references/dont-forbidden.md.
Small business beats big competitor
Local + niche levels the field: genuine first-hand Experience, review velocity/recency,
narrow topical depth, and proprietary data beat a national brand's weak local execution.

Market packs
- UK: Companies House number, Gas Safe / NICEIC / TrustMark / Checkatrade / FENSA /
MCS / HETAS, UK directories. references/market-uk.md.
- HU: cégjegyzékszám + adószám (validated, incl. adószám CDV checksum), Árukereső
Megbízható Bolt, Cylex / Arany Oldalak; Hungarian-language AI is under-served =
first-mover edge. references/market-hu.md.
Conflict precedence
EEAT is an SEO-tier concern. If a signal conflicts with Safety/Legal,
Accessibility, or Performance, those win (see the skills CONFLICT-MATRIX). Example:
don't ship heavy author-photo galleries that blow the LCP budget — optimise first.
Workflow
- Run
npm run audit against the built site (or a page) with the right --market.
- Fix every
fail; weigh each warn; ignore not_found.
- For any schema-expressed signal, hand off to schema-entity-graph / schema-audit.
- Re-run until exit
0. Then run astro-audit for the full pre-deploy gate.

Use when a page or site needs Experience/Expertise/Authoritativeness/Trust signals, author credibility, first-hand-experience proof, trust pages (about/contact/privacy/returns), NAP + company registration display, review/trust-mark surfacing, AI-crawler access in robots.txt, or answer-first content for ChatGPT/Gemini/Perplexity/AI Overviews. Also triggers on "EEAT", "E-E-A-T", "GEO", "AEO", "AI search visibility", "get cited by AI", "trust signals", "author bio", "local trust", or making a small/niche business outrank larger competitors. Runs a deterministic auditor with runnable tests. Delegates JSON-LD generation to schema-entity-graph and JSON-LD validation to schema-audit; delegates copy voice to humanise-copy.4---56# E-E-A-T Signals — audit + strengthen (Astro)78Make a page **demonstrate** Experience, Expertise, Authoritativeness and Trust to9both humans and AI engines — and verify it with a runnable auditor.
