Compare crawl snapshots
Use crawl-diff after a deploy, migration, or planned technical change. It
crawls a bounded same-origin set, saves the result, and compares it with the
previous saved run for the same surface. This turns status, indexability,
canonical, metadata, content, and inventory movement into a review queue. It
does not prove that a changed page affected search performance.
Run the report
With MCP, call seo_list_reports with {"category":"monitoring"}, then call
seo_describe_report with {"id":"crawl-diff"}. Run the exact schema with
seo_run_report, for example
{"id":"crawl-diff","params":{"startUrl":"https://example.com/","site":"sc-domain:example.com","limit":250,"js":false,"refresh":true}}.
CLI parity uses the same definition:
