# seo-sitemap Audits an existing XML sitemap or builds a new one from industry templates. Useful when broken URLs and structure errors need to surface fast. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 7200 installs · ★ 21467 - Author: AgriciDaniel - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/AgriciDaniel/claude-seo/tree/HEAD/skills/seo-sitemap/SKILL.md - Updated: 2026-10-22 - HTML: https://affpapa.org/en/nevibecode/skills/seo-sitemap ## What it does The skill runs in two modes. The first takes a site URL, reads every `Sitemap:` line in robots.txt, validates cross-host targets through an SSRF-safe fetch layer, and still probes common paths when a declared sitemap is stale or invalid. Each URL is checked for XML format, an HTTP 200 response, the 50,000 URL and 50MB uncompressed per-file caps, and a `` that is a valid W3C Datetime. Image, video and news extensions get their own pass: separate tags, separate limits, and news files cap at 1,000 entries instead of 50,000. The second mode asks for a business type or detects it from the site, loads an industry template from `../seo-plan/assets/`, plans the structure with you, and writes valid XML. At 30 or more location pages it warns about unique content; at 50 it stops and asks for justification. Splitting into an index happens at whichever comes first, 50,000 URLs or 50MB. Output is either `VALIDATION-REPORT.md` with issues ranked by severity, or `sitemap.xml` plus `STRUCTURE.md` describing the architecture. Fetched pages and third-party responses are treated as untrusted data, so text that addresses the agent lands in the report as a finding rather than a command. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add AgriciDaniel/claude-seo --skill seo-sitemap -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/seo-sitemap/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/seo-sitemap/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add AgriciDaniel/claude-seo --skill seo-sitemap -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/seo-sitemap/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add AgriciDaniel/claude-seo --skill seo-sitemap -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/seo-sitemap/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install AgriciDaniel/claude-seo seo-sitemap ``` 2. **Manually: put the files in place** - File: `.github/skills/seo-sitemap/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add AgriciDaniel/claude-seo --skill seo-sitemap -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/AgriciDaniel/claude-seo --path skills/seo-sitemap ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/seo-sitemap/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add AgriciDaniel/claude-seo --skill seo-sitemap -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/AgriciDaniel/claude-seo/tree/HEAD/skills/seo-sitemap/SKILL.md ## When to use it - check an XML sitemap for broken and non-canonical URLs - generate sitemap.xml from scratch with an industry template - split a sitemap into an index once it passes 50,000 URLs - find deprecated `` and `` tags and drop them - compare crawled pages against the sitemap to spot gaps ## Example prompts - Audit the sitemap at https://example.com and list issues by severity - Generate an XML sitemap for an online store, we'll plan the structure step by step - Check the news sitemap: is it over 1,000 entries and are all articles from the last 2 days ## Source text · SKILL.md · MIT Below is the content of a third-party file.

Use only entries in `found`; preserve declared failures as findings instead of treating a robots.txt line alone as proof that a sitemap works. ### Validation Checks - Valid XML format - Per-file limit: **≤50,000 URLs AND ≤50MB uncompressed** (whichever is hit first) - All URLs return HTTP 200 - `` accurate: must be a valid **W3C Datetime** and reflect the **last significant content change** (main content, structured data, links, not copyright/boilerplate edits). Google only honours `` when consistently and verifiably accurate, so warn when values are suspiciously uniform or newer than the page's real content. - No deprecated tags: `` and `` are ignored by Google - Sitemap referenced in robots.txt - Compare crawled pages vs sitemap; flag missing pages ### Quality Signals - Sitemap index file if >50k URLs - Split by content type (pages, posts, images, videos) - No non-canonical URLs in sitemap - No noindexed URLs in sitemap - No redirected URLs in sitemap - HTTPS URLs only (no HTTP) ### Common Issues | Issue | Severity | Fix | |-------|----------|-----| | >50k URLs in single file | Critical | Split with sitemap index | | >50MB uncompressed single file | Critical | Split with sitemap index | | Non-200 URLs | High | Remove or fix broken URLs | | Noindexed URLs included | High | Remove from sitemap | | Redirected URLs included | Medium | Update to final URLs | | All identical lastmod | Low | Use actual modification dates | | Priority/changefreq used | Info | Can remove (ignored by Google) | ### Extension sitemaps (image / video / news) Google documents three subtypes with their own rules, validate per-subtype: ```` END THIRD-PARTY FILE 9cefd188840ed4a0 The third-party file has ended.
