Compare crawl snapshots

A crawl diff is useful only when its inputs are comparable. This report surfaces page, issue, response, indexability, title, content, and summary changes between two saved snapshots. By default, after means the latest report and before means the previous report, optionally within one site filter.

Run it

For MCP, use seo_list_reports with category crawl only for discovery. Call seo_describe_report with { "id": "compare-crawl-reports" }, then call seo_run_report with:

{
  "id": "compare-crawl-reports",
  "params": {
    "after": "latest",
    "before": "previous",
    "site": "sc-domain:example.com"
  }
}
