Yandex Metrica

Analytics

Yandex Metrica web analytics with optional session-replay (Webvisor).

How to block it until consent

Analytics — consent required. Loads tag.js from mc.yandex.ru (or mc.yandex.com); session replay (Webvisor) loads from mc.webvisor.org. Sets _ym_uid, _ym_d, _ym_isad, _ym_visorc* first-party cookies. Worth flagging on EU sites — Yandex is a Russian processor with extra GDPR transfer considerations.
