About this skill

seo-entity-linking (M6)

Entity linkage tells search engines and AI systems which real-world thing a page is about and ties it to the Knowledge Graph. Reference: references/schema-tier1.md (the sameAs/@id/Person+Organization rules). This module owns the sameAs detail M5 defers here.

Inputs

Work from the PageSnapshot named in your dispatch envelope: read parsed from <run_dir>/pages/<slug>.json (jsonld[], anchors[]); Grep pages/<slug>.html for verbatim evidence; site artifacts live in <run_dir>/site/{robots.json,sitemaps.json,discovery.json}. Deterministic findings already emitted by audit.mjs are listed in <run_dir>/findings.deterministic.json — do not re-emit those ids; add model-judged findings only. If invoked directly with a URL/path and no snapshot exists, first run node "${CLAUDE_PLUGIN_ROOT}/scripts/snapshot.mjs" <target> --out "${CLAUDE_PLUGIN_DATA}/runs" and use the printed snapshot path.

Audits

Working from the PageSnapshot (parsed_rendered when render.used is not none, else parsed):

  1. sameAs identity links: for Organization/Person entities, check for sameAs[] resolving to canonical identities — Wikidata QID, Wikipedia, LinkedIn, Crunchbase, official social/company profiles. Wikidata is the strongest Knowledge Graph target.
  2. Primary entity defined: confirm exactly one clear primary entity per page (via @id + mainEntity/mainEntityOfPage), not an ambiguous or missing subject.
  3. Entity consistency (local): for LocalBusiness, verify NAP (name, address, telephone) in schema matches visible on-page NAP and is internally consistent across blocks.
  4. Entity density: count distinct linked/marked entities (@idd nodes, sameAs targets, about/mentions) — flag thin pages with no resolvable entity references.

Fixes

  • AUTO (fixable: auto): inject a sameAs[] array on Organization/Person using only user-confirmed URLs, and add about/mentions entity references to existing schema. Additive, deterministic diffs for fix. Never invent identity links — if a URL is unconfirmed, leave a clearly-marked TODO placeholder the user fills.
  • PROPOSED (fixable: proposed): a candidate Wikidata/LinkedIn match found by lookup — drafted for per-item human accept, never auto-written.
  • ADVISORY (fixable: advisory): "establish a Wikidata entity / claim profiles" when none exist — guidance only, the tool writes nothing.

Verification

  • dom_assert: confirm sameAs/@id/mainEntity present and well-formed in the parsed JSON-LD.
  • Resolve each sameAs URL (Tier 1 Wikidata lookup) to confirm it is live and refers to the asserted entity — a dead or mismatched link is a fail, not a pass.
  • When the live lookup tier is unavailable, status is needs_api, never a false pass.

Findings

Emit findings per schema/finding.schema.json; axis ai; confidence directional throughout — none of these is documented by a vendor. Severity policy: 5 is reserved for catastrophic, eligibility-killing facts at site/template scope; 4 major · 3 moderate · 2 minor · 1 cosmetic · 0 informational — and only an established severity-5 fail in an active category can cap a score (references/scoring-model.md).

  • M6.organization.missing_sameas — Organization with no sameAs[] (fail, severity 3, fixable: proposed).
  • M6.page.no_primary_entity — no single defined primary entity (@id / mainEntity) on the page (warn, severity 3, fixable: advisory).
  • M6.entity.thin_density — no resolvable entity reference anywhere in the markup on a page that names real organizations, people, or products (warn, severity 3, fixable: advisory).
  • M6.person.no_wikidata_link — an author Person with no Wikidata/LinkedIn identity link (warn, severity 2, fixable: proposed).
  • M6.sameas.unresolvable — a declared sameAs URL that 404s or points at a different entity (fail, severity 3, fixable: proposed). Each finding: evidence.observed quotes the page (the entity block or its absence); verification.reproduce is a runnable assertion/lookup; expected_impact is banded + confidence-tagged (no naked %).

Honesty

  • A sameAs link does not force entry into the Knowledge Graph and produces no guaranteed ranking lift — it is a disambiguation signal, so impact stays directional, never established.
  • Never fabricate, guess, or "best-effort" an identity URL to inflate entity density — a wrong sameAs actively misleads engines and is worse than an empty array. Confirmed-only, or leave it as a TODO.
  • Entity density is a proxy for "this page is about something specific and resolvable", not a metric any engine publishes; do not chase the number for its own sake.
