SITEMAP IMPORT
Discover a sitemapUse complete discovery JSON exports
Baseline is the earlier or reference sitemap discovery. Current is the later discovery. The complete report contract and request scope are validated before comparison.
XML
Load both sitemap exports to begin.
No sample URL changes, indexing estimate, or manufactured sitemap score appears before two valid evidence sets are present.
Release review
Treat sitemap declarations as discovery evidence
Keep discovery scope aligned
Use the same root sitemap and nested-index setting when comparing releases or scheduled exports.
Investigate absence before acting
Review XML generation, nested sitemap availability, URL limits, response failures, and the live page before calling an entry removed.
Verify page state separately
Use URL health, crawl evidence, canonical inspection, and first-party provider data when a decision depends on availability or indexing.
