# Sitemap URL Inventory - New, Changed & Removed URLs — workflow

## Choose this tool

Use public XML or gzip sitemaps to maintain a source-linked URL inventory and identify additions, metadata changes and removals from complete comparable sitemap checks.

Useful output columns: `url`, `presence`, `comparisonStatus`, `lastmod`, `priority`, `inventoryComplete`, `observedAt`.

## Practical workflow

Start with one known sitemap, optionally filter URL prefixes, and inspect coverage in SUMMARY. Store a complete baseline before enabling recurring comparisons. Review additions and publisher-reported lastmod changes; verify any absent URL directly before interpreting it as a deleted page.

## Check the fit

Declared sitemap entries only, not a crawl, page availability check or search index report. Lastmod and priority are publisher claims. Removed means absent from a complete comparable sitemap inventory, not that the page no longer exists. Child maps are bounded and must remain on the original origin.

## Real output sample

One selected row from a 2026-11-05 run. Selected original scalar fields from one actual saved observation; nested data and private artifact links are omitted.

Run: vhX1IbJfFBeLo6ln5. Summary status: ok. Incomplete: false.

Dated bounded release evidence for this exact input and build. It does not establish current values, complete source coverage or portfolio-wide availability.
