YaDirectFetcher

YaDirectFetcher is a Yandex crawler used to fetch landing pages and assets for advertising purposes within the Yandex.Direct ecosystem. It retrieves content to evaluate ad relevance, page availability, redirects, and compliance with advertising policies. This crawler supports both initial ad review and ongoing campaign monitoring. It is not a general search crawler and does not index content for Yandex Search. Blocking it may disrupt ad approval or delivery. Crawl activity is targeted and low-volume, typically triggered by ad creation, updates, or periodic quality checks across Yandex.Direct campaigns. It does not use the robots.txt at all and thus global robots.txt user agent (*) rule and its own directives are completely ignored. RobotSense.io verifies YaDirectFetcher using Yandex’s official validation methods, ensuring only genuine YaDirectFetcher traffic is identified.
