YandexAdditional is a Yandex service crawler used to interpret and apply robots.txt rules that control whether indexed page content can be used in Yandex AI-generated responses. It operates only on pages that have already been indexed by Yandex’s primary crawler and does not request new pages or trigger indexing. The bot analyzes access directives to ensure content usage complies with site owner preferences in AI features. It does not perform independent crawling. Its activity is internal and policy-driven, supporting correct enforcement of robots-based restrictions for Yandex’s AI response systems. It ignores the global robots.txt user agent (*) rule. RobotSense.io verifies YandexAdditional using Yandex’s official validation methods, ensuring only genuine YandexAdditional traffic is identified.

This bot does not honor Crawl-Delay rule.
