seo-entity-linking

seo-entity-linking is a skill for Claude Code from Hainrixz/claude-seo-ai. It costs 88 tokens per session (1,319 once invoked), scanned A, original, MIT.

A website audit and improvement guide for connecting a page to clear real-world entities, such as a company, person, or local business. It covers identity links, business details, and machine-readable entity information.

In plain words
What is it for?
Use it to check or add identity links, define a page’s main entity, verify local business name, address, and phone details, and measure how clearly entities are represented.
Why use it?
It helps search engines and AI systems understand exactly who or what a page is about and avoid conflicting identity details.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

seo-entity-linking scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.
