# seo-sitemaps (M17) Sitemaps are the discovery contract you hand the crawler — they should list exactly the canonical, indexable URLs and nothing else. Schema rules for related markup: `references/schema-tier1.md`. ## Audits Working from the PageSnapshot (`rendered_dom` if present, else `raw_html`) plus fetched `/sitemap.xml` and `/robots.txt`: 1. **Presence & validity**: locate XML sitemap(s) (`/sitemap.xml`, robots `Sitemap:` lines, sitemap index); parse as well-formed XML against the sitemaps.org schema. 2. **Size limits**: each sitemap `<=50,000` URLs and `<=50MB` uncompressed; if exceeded, expect a sitemap index splitting the set. 3. **Extensions**: where relevant, validate `image:`, `video:`, and `news:` namespace entries (correct namespace declared, required child elements present). 4. **lastmod accuracy**: `<lastmod>` is valid ISO 8601 and reflects real last-modified time — not a build-time stamp on every URL (which trains crawlers to ignore it). 5. **robots referencing**: at least one absolute `Sitemap:` line in `robots.txt`. 6. **Sitemap-to-canonical consistency**: no URL in the sitemap is `noindex`, redirected, 4xx/5xx, or non-canonical (self-referencing canonical only). Cross-check indexability with M-indexability. 7. **Orphan reconciliation**: diff sitemap URLs against the internal link graph — flag indexable pages absent from the sitemap and sitemap URLs unreachable by internal links. ## Fixes - **AUTO**: generate or repair XML sitemap entries (correct `<loc
