Sogou Spider — Sogou's web crawler
Sogou Spider is the crawler for Sogou, a Chinese search engine. Its user agent contains the Sogou identifier. English-language documentation is limited and verification options are not well published, so this entry is marked partially verified.
What this means
Sogou is a Chinese search engine, and its crawler is commonly referred to as Sogou Spider. Its user agent contains the Sogou identifier. If your audience includes Chinese-speaking users, Sogou crawling reflects Sogou discovering and indexing your content.
Because public English-language documentation is limited, the precise token form and behaviour should be confirmed against Sogou's own sources. This entry is therefore marked partially verified.
Verification caveats
Stable, well-published verification methods for Sogou Spider are limited compared with Google or Bing, and documentation is largely in Chinese. Treat the user agent as a claim, since it is spoofable, and avoid assuming behaviour that is not documented by Sogou.
- User agent contains the Sogou identifier
- Chinese search engine
- Limited English documentation — partially verified
How it appears in analytics and logs
A request whose user agent contains the Sogou identifier is likely Sogou's crawler fetching a URL — a bot event. Sogou serves Chinese-language search; English documentation and verification methods are limited.
Diagnostic use case
Recognise Sogou Spider crawling when targeting Chinese-language audiences, and apply robots.txt policy with the caveat that verification is limited.
What WebmasterID can help detect
WebmasterID classifies Sogou crawling server-side as search-crawler activity and shows it separately from human traffic, so its crawl footprint is visible without log parsing.
Common mistakes
- Assuming Google-style verification works for Sogou.
- Trusting a Sogou user agent without caution.
- Counting crawler hits as human visits.
Privacy and accuracy notes
Identification uses the user agent — no human identity. WebmasterID records Sogou crawling as a bot event, separate from human analytics.
