About this crawler
Yandex Search's main crawler.
Usually means: The page is being discovered or refreshed so it can appear in search or AI search results.
User agent
YandexBot
MetricRaven matches this token anywhere in the request's user agent, ignoring case. Operators add version numbers and browser text around it, for example "YandexBot/1.0".
IP verification
Yandex publishes no IP ranges for YandexBot, so requests are identified by user agent only and recorded as unverified. Anyone can send this user agent.
Control it in robots.txt
User-agent: YandexBot Disallow: /private/
Well-behaved crawlers re-read robots.txt within a day or so.
Questions
- What is YandexBot?
- Yandex Search's main crawler. MetricRaven groups it under Search indexes: search engines and AI search keeping their index fresh.
- How do I verify that a request really comes from YandexBot?
- Yandex publishes no IP ranges for YandexBot, so only the user agent identifies it. Anyone can send that string, so treat it as a claim.
- How do I block or allow YandexBot?
- Add a robots.txt group for "YandexBot" with the paths to allow or disallow. Fetchers that act for a user may ignore robots.txt; block those at your server or firewall instead.
- How can I see when YandexBot visits my website?
- Most crawlers never run JavaScript, so browser analytics miss them. MetricRaven's @metricraven/ai-crawl package reports crawler requests from your server, verifies their IPs against published ranges, and shows which pages each crawler reads.
