How to read this page
Eligibility and limits
- Each row is the newest successful, request-complete, uncapped passive lead visit for one canonical site within this page's measurement cohort, which is not always the site's newest such visit.
- Every row here was measured under one cohort (shields-request-context-v2-adblock-rust-0.13.3-request-method-v1-playwright-1.63.0+subject-validity-v4+detector-coverage-v2+fingerprint-surface-v2, schema v1, producer unrecorded, GPC not requested), which is this page's denominator. Another category can publish a different cohort, so these medians are comparable within this page and not against another category's.

- Failed loads, incomplete recordings and accept/reject consent-interaction arms are excluded.
- Third-party tracking-service request counts are lower bounds derived from retained request rows whose recorded host matched a reviewed service-catalog suffix and from the recorded ServiceRole taxonomy.
- Category membership is editorial. The corpus is curated and is not a random or representative web sample.
- A controlled visit is one observation. Ads, experiments, caching, location and bot detection can change what loads.
- Blocking pairs simulate Brave's ad-block engine and default lists in the scanner; they are not live Brave-browser visits or counts of individually blocked requests.
