Analyze GSC sampling / anonymization impact
analyze_sampling_impactRead-only
Estimates how much click/impression data Google Search Console hides through anonymization (privacy-threshold row dropping) for a property over a date range. Compares the per-day totals against the summed top query rows and top page rows; the gap is the lost share. On the live API path this reveals true GSC sampling. On the ClickHouse warehouse path the data is unsampled, so the reported loss reflects only top-N row truncation (see the note field). The response dataSource says which path served the request. Date range is optional: omit startDate/endDate to analyze the last 28 settled days (data lags ~2-3 days).
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| endDate | No | Optional. Window end as YYYY-MM-DD (e.g. 2026-05-31). You do NOT need to know today's date or the latest available date: omit this and the server uses the latest settled Search Console date (data lags ~2-3 days behind today). Never pass null or the string "null". | |
| siteUrl | Yes | ||
| startDate | No | Optional. Window start as YYYY-MM-DD (e.g. 2026-05-03). You do NOT need to know today's date. Omit BOTH startDate and endDate to analyze the last 28 settled days automatically (Search Console data lags ~2-3 days). Never pass null or the string "null". | |
