How to block coccocbot in robots.txt
coccocbot is the crawler operated by Cốc Cốc, a search engine and browser popular in Vietnam. This page gives the robots.txt rule to disallow the coccocbot token and explains that it matters mainly if your audience includes Vietnamese-market users.
What coccocbot is
coccocbot is the crawler for Cốc Cốc, a search engine and web browser with significant usage in Vietnam. If you target Vietnamese-market visitors, allowing it supports your visibility in that search engine; if you do not, blocking it removes a crawler that brings you no relevant audience.
Cốc Cốc documents the crawler and its tokens. Note that it has used variant tokens (for web and image crawling), so check your logs for the exact token reaching you.
The rule
To disallow coccocbot site-wide, target its token:
User-agent: coccocbot Disallow: /
If you see image-specific variants of the token in your logs, add matching rules for those too. Match tokens exactly. robots.txt is a request to compliant crawlers and is not an access-control mechanism.
- Token: coccocbot (variants exist for web and image crawling)
- Operator: Cốc Cốc (Vietnam search engine and browser)
- Relevant mainly to Vietnamese-market audiences
How it appears in analytics and logs
A request carrying the coccocbot token is the Cốc Cốc search crawler fetching a URL. Seeing it usually means you have some Vietnamese-market visibility; blocking it can reduce that.
Diagnostic use case
Disallow coccocbot if you do not serve a Vietnamese-market audience and want to reduce crawl load from a regional search engine you do not target.
What WebmasterID can help detect
WebmasterID classifies coccocbot by its token as a regional search crawler, separate from human analytics, so you can confirm whether a disallow rule changed its activity.
Common mistakes
- Blocking coccocbot while targeting Vietnamese-market visitors.
- Assuming one token covers web and image variants — check your logs.
- Treating robots.txt as enforcement rather than a request.
Privacy and accuracy notes
Blocking coccocbot is a publishing-policy choice in a public file. It involves no visitor data and is not an access-control boundary.
