Sogou web spider vs image spider
Sogou, a major Chinese search engine, operates more than one crawler variant, including a general web spider and an image-oriented spider. Separating them helps operators read Sogou crawl activity by purpose and set policy accordingly. Sogou documents its spiders primarily in Chinese; some specifics are not exhaustively published in English, so this entry is partially verified.
What this means
Sogou is a major Chinese search engine and runs distinct crawler variants for different surfaces. A general web spider crawls pages for web search; an image-oriented spider focuses on images for image search.
Reading these separately matters when you want to allow web crawling but manage image crawling differently, or when diagnosing which Sogou surface is generating load on a China-facing site.
How they identify themselves
The Sogou spiders use Sogou-family user-agent tokens (for example a general web spider token and an image-focused token) with self-identifying URLs. Match on the stable family tokens. Sogou's most detailed documentation is in Chinese, so verify variant specifics against Sogou's guidance rather than asserting unverified English-only strings.
This entry covers the existing general Sogou spider entry from a variant-comparison angle; see the Sogou Spider entry for the base crawler.
- Sogou runs more than one crawler variant
- Web spider for pages; image spider for images
- Most authoritative docs are in Chinese
How it appears in analytics and logs
A Sogou web-spider token indicates general-web crawling for Sogou search; an image-spider token indicates image crawling. Reading them separately tells you which Sogou surface is crawling, relevant mainly to China-facing sites.
Diagnostic use case
Distinguish Sogou web crawling from Sogou image crawling in logs, and set robots.txt policy for the variants if you target the Chinese market.
What WebmasterID can help detect
WebmasterID classifies Sogou's web and image spiders distinctly within the Sogou family, so you can see which Sogou surface is crawling without conflating web and image coverage.
Common mistakes
- Assuming Sogou uses a single crawler for all surfaces.
- Counting Sogou crawl hits as human visits.
- Inventing exact variant strings instead of matching the documented family tokens.
Privacy and accuracy notes
Sogou spiders are identified by user-agent tokens only. They are crawlers, not people; WebmasterID records them as bot events with no visitor identity.

- Baiduspider-image (Baidu image crawler)
Baiduspider-image is the image-oriented variant of Baiduspider, the crawler for Baidu, China's leading search engine. It fetches images to support Baidu image search, separate from the general-web Baiduspider. Baidu documents Baiduspider and its variants; some specifics are documented in Chinese and not exhaustively in English, so this entry is partially verified.
- Regional search engines overview
In several markets a regional search engine leads instead of Google: Yandex in Russian-language search, Baidu in China, Naver in South Korea, Seznam in the Czech Republic, and Coc Coc in Vietnam. Recognising their crawlers matters because being indexed by them is how you reach those audiences.
