Sitemap Delta: New Pages & Confirmed Removals

Sitemap Delta

Turn public XML sitemap changes into structured reports for content pipelines and SEO workflows. Find new URLs, changed sitemap metadata, and URLs missing from two consecutive complete observations. No LLM, browser renderer, or proxy is required.

Start a run

Enter one to three complete sitemap URLs in sitemapUrls. The first run creates a baseline. Download the SNAPSHOT key-value record and pass its complete JSON as previousSnapshot on your next run. Your calling automation owns scheduling and passing state. This Actor does not automatically reuse another run's storage.

What you receive

One dataset report per successfully completed sitemap root: sitemapUrl, status, urlCount, sitemapFiles, counts, changes, and a stable metadata fingerprint. Each change includes a URL and a classification: added, metadata_changed, or no_longer_in_sitemap.

The first absence is pending, not a removal. A second complete absence confirms that the URL is no longer listed in the sitemap. This does not establish that the page is deleted, deindexed, unavailable, or that its content changed. lastmod, changefreq, and priority are publisher declarations, not independently verified facts. Page contents are not fetched.

SNAPSHOT holds complete state for the next comparison. DIAGNOSTICS lists failures. DELIVERY reports whether all reports reached the dataset. A failed root preserves its previous state. A truncated traversal does not produce a misleading complete report. A spending-limit interruption withholds the next snapshot; retain your preceding snapshot.

Pricing

Launch price: $0.02 per completed sitemap report, plus $0.005 per start at 256 MiB. Platform usage is included. One report can cover up to 5,000 URLs across up to 20 sitemap files. A completed baseline or unchanged sitemap is still a billable report. Failed roots are not report charges; the start charge still applies. The price displayed before your run is authoritative.

Scope and limits

XML urlset and sitemapindex, XML namespaces, gzip payloads, and same-host child sitemaps are supported. Up to three roots, 20 files and 5,000 current URLs per root; 2 MiB compressed and decompressed per response; a 45-second traversal deadline per root. Cross-host sitemap entries, oversized results, inconsistent duplicates, and unsafe network destinations are rejected. HTTP redirects are bounded. A site may block requests; no CAPTCHA or access-control bypass is attempted.

Text sitemaps, robots.txt discovery, RSS, hreflang, image/video extensions, content hashing, page-status checks, and automatic snapshot persistence are outside this version's scope. Use a child sitemap directly if a root index exceeds the traversal limits.

Support

Open an Actor issue with the public sitemap URL and run ID. Do not include credentials or private data. This is an independent utility, not affiliated with search engines or the websites it reads. Use only sources and data you are entitled to access.
