seranking/seo-sitemap
Pull a domain's XML sitemap (and sitemap-of-sitemaps), then compare against the most recent SE Ranking website audit. Surfaces (a) sitemap entries the crawler couldn't find (orphans from the sitemap), (b) audit pages missing from the sitemap (probably an oversight), (c) sitemap entries that are now 404, (d) lastmod inconsistencies. Use when the user asks for "sitemap analysis", "check my sitemap", "sitemap vs audit", "missing pages", "orphan pages", or "sitemap health".

Compare a domain's XML sitemap against the most recent SE Ranking website audit. Surface what the sitemap claims vs what the crawler actually found, in both directions.

Without an existing audit, this skill has nothing to compare against — chain seo-technical-audit first.DATA_listAudits → confirm an audit exists for this domain. If none, surface a clear message: "Run seo-technical-audit first; this skill compares the sitemap to that audit's crawl."done audit by default.mcp__firecrawl-mcp__firecrawl_map is available, Mode-2 (URL discovery via crawl) is offered when the sitemap is missing or suspect. Cost: ~0.5 Firecrawl credits per URL discovered, hard cap 500 URLs (~250 credits). Without Firecrawl, the skill runs Mode-1 only and notes the gap if Mode-2 was needed. User may pass --no-firecrawl to force Mode-1 even when Firecrawl is available (saves credits at the cost of orphan/missing analysis when sitemap is broken).WebFetch (sitemap) + mcp__firecrawl-mcp__firecrawl_map (optional Mode-2)https://{domain}/sitemap.xml. If 404, fetch /robots.txt and look for Sitemap: directives. For sitemap-of-sitemaps, recursively fetch each child sitemap. Build the canonical URL list from the sitemap.DATA_getCrawledPages count, or (c) the user explicitly requests --discover. Always surface the trigger and the cost estimate to the user before running Mode-2.firecrawl_map(url=domain, limit=500). The response is the URL list Firecrawl could discover from the homepage and internal linking. Use this list as the "sitemap-equivalent" in step 6 — the diffs run identically, just with discovered URLs in place of declared sitemap URLs.SITEMAP.md: Mode-2 (Firecrawl URL discovery) needed but Firecrawl not installed — sitemap-vs-audit diffs run on partial data only.DATA_getCrawledPagesDATA_getDomainPagesDATA_getAuditPagesByIssueDATA_getCrawledPages (status 200, indexable) that don't appear in the sitemap.

Validate it (step 6). <priority> and <changefreq> have been explicitly ignored by Google for years (per Google's sitemap docs — "Google ignores priority and changefreq values"). Don't validate them; if present, flag as low-signal noise the user can strip to shrink the sitemap.SITEMAP.mdCreate a folder seo-sitemap-{target-slug}-{YYYYMMDD}/ with:

Top-level: SITEMAP.md + recommended-sitemap-diff.md. The seven raw step files (01-sitemap-raw, 01b-firecrawl-discovered, 02-audit-pages, 03-missing-from-sitemap, 04-orphans-from-sitemap, 05-broken-entries, 06-lastmod-issues) are consolidated into a single evidence/source-data.md document with the same per-step section headers — a reader who needs to replay the diff has all raw inputs in one file rather than seven.
SITEMAP.md follows this shape:
# Sitemap Analysis: {domain}
> Sitemap pulled {YYYY-MM-DD} · Audit reference {audit-date}
## Mode
- **Mode-1 (sitemap-vs-audit):** {ran / skipped — no sitemap reachable}
- **Mode-2 (Firecrawl URL discovery):** {ran with {n} URLs / not triggered / triggered but Firecrawl not installed}
## Health summary
| Metric | Value | Status |
|---|---|---|
| Sitemap URLs (Mode-1) | {n} | — |
| Discovered URLs (Mode-2, if ran) | {n} | — |
| Audit crawled URLs (200, indexable) | {n} | — |
| Missing from sitemap (probable adds) | {n} | {🔴 if >5%} |
| Orphans from sitemap (probable cuts or link-ins) | {n} | {🟡 if >5} |
| Broken sitemap entries (non-200) | {n} | {🔴 if >0} |
| Lastmod issues | {n} | {🟡 if uniform; 🔴 if stale} |
## Recommended changes
### Add to sitemap ({n} URLs)
- {URL} — found by crawler at depth {n}, status 200, indexable.
- ...
### Remove from sitemap ({n} URLs)
- {URL} — returns {status code}.
- ...
### Investigate (orphan from sitemap, {n} URLs)
- {URL} — in sitemap but not reachable via internal links. Either link from {suggested parent} or remove from sitemap.
- ...
### Fix lastmod ({n} URLs)
- {URL} — lastmod is {date} but the audit crawled the page on {date} and detected changes since.
- ...
## Validation
- Total URL count: {n} ({✓ under 50k limit | ✗ exceeds — split into sitemap-of-sitemaps})
- Referenced in robots.txt: {✓/✗}
- HTTPS consistency: {✓/✗}
- Encoding: {✓/✗}
## Apply
- See `recommended-sitemap-diff.md` for the proposed sitemap.xml changes.
- After applying, re-run `seo-technical-audit` to refresh the crawl, then re-run this skill to verify.
seo-technical-audit first. Without an audit, this skill has nothing to compare.<priority> and <changefreq> are dead signals — Google explicitly ignores both. Don't waste time tuning them; if your sitemap generator emits them, the bytes are pure overhead. <lastmod> is still consumed, so keep that one accurate.seo-drift to track sitemap composition over time (URL count, lastmod patterns).getCrawledPages and getDomainPages calls). Mode-2 adds Firecrawl credits at ~0.5 per discovered URL — surface the estimate before triggering.Take seranking/seo-sitemap from the repository into ~/.claude/skills for personal

The agent identifies a skill by the name field in its header. Two skills with the
same name cannot sit side by side — one of them will be ignored.
