Decaying queries and pages

Use this report to identify retained query/page combinations that lost clicks between adjacent equal-length periods or year-over-year windows. It requires evidence in both windows, excludes URL shifts, and groups returned rows by diagnosis signal and page template. This avoids turning a row missing from GSC's retained query data into zero traffic. The report shows observed movement, not why it happened.

Run the report

Use the compact MCP flow:

1. Call seo_list_reports with {"category":"opportunities"}.
2. Call seo_describe_report with {"id":"decaying"}.
3. Call seo_run_report with {"id":"decaying","params":{"site":"sc-domain:example.com","days":28,"comparison":"previous-period","limit":20,"minDropPct":20,"minPreviousClicks":10,"minClickLoss":5}}.

The CLI uses the same report definition:

seo reports describe decaying --json
seo reports run decaying --params '{"site":"sc-domain:example.com","days":28,"comparison":"previous-period","limit":20,"minDropPct":20,"minPreviousClicks":10,"minClickLoss":5}' --json
