seo-internal-linking

# seo-internal-linking (M10) Internal links distribute crawl priority and topical authority and tell search engines (and AI crawlers) how your pages relate. Reference: `references/schema-tier1.md` for the entity/`@id` linkage this topology should mirror; M6/seo-entity-linking owns external `sameAs`. ## Inputs Work from the PageSnapshot named in your dispatch envelope: read `parsed` from `<run_dir>/pages/<slug>.json` (`anchors[]` with `region`/`internal`/`anchor`, `landmarks`) and the crawl graph in `<run_dir>/crawl.json` (`graph.edges`, `pages[].inlinks`, `templates[]`); 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. **Pillar/cluster topology**: classify each URL (pillar hub vs. cluster page) and confirm clusters link up to their pillar and the pillar links down to its cluster — gaps break the hub-and-spoke model. 2. **Contextual in-body links**: count links inside `<main>`/`<article>` prose (target ~3-5 descriptive i...
