How to block ZoominfoBot
ZoominfoBot is the crawler associated with ZoomInfo, a business-data platform that compiles company and contact information from public web pages. This page shows how the crawler identifies itself, the robots.txt token to target, and why a Disallow is a request rather than enforcement against a non-compliant fetcher.
What ZoominfoBot is
ZoominfoBot is the web crawler associated with ZoomInfo, a B2B data platform that builds company and professional-contact records partly from publicly available web pages. Operators who do not want their public content folded into that dataset can disallow the crawler.
ZoomInfo documents a self-identifying crawler; match on the documented robots.txt token rather than a full version string, because version components change over time.
- robots.txt token: ZoominfoBot
- User agent contains the ZoominfoBot token plus a self-identifying URL
- Purpose: business-contact and company-data aggregation
robots.txt rule
To ask ZoominfoBot to stay off your whole site:
User-agent: ZoominfoBot Disallow: /
This targets only that token and does not affect search engines or AI crawlers. robots.txt is honoured by compliant crawlers; it is not an access-control boundary. A fetcher that ignores robots.txt — or copies the user agent — is not stopped by this rule, so confirm with crawl behavior whether the crawler actually backed off.
How it appears in analytics and logs
Requests carrying the ZoominfoBot token are data-aggregation crawl events, not human visits. Sustained hits mean a business-intelligence platform is harvesting your public content; they belong in bot analytics, not audience metrics.
Diagnostic use case
Stop a business-data aggregation crawler from harvesting your public pages for ZoomInfo's company and contact datasets, and confirm the rule reached the right token.
What WebmasterID can help detect
WebmasterID classifies ZoominfoBot server-side as a crawler and shows whether it still reaches your pages after you add a robots.txt rule, so you can confirm a compliant crawler backed off.
Common mistakes
- Assuming robots.txt enforces the block rather than requesting compliance.
- Misspelling the ZoominfoBot token so the rule never matches.
- Counting aggregation-crawler hits as human sessions in analytics.
Privacy and accuracy notes
Blocking ZoominfoBot uses only the request user-agent token. No visitor identity is involved — a crawler is not a person, and WebmasterID records the crawl as a bot event separate from human analytics.

- robots.txt basics: what it does and what it cannot do
robots.txt is a plain-text file at your site root that tells compliant crawlers which paths they may request. This page covers the directives, how user-agent groups are matched, and the limits that trip people up: robots.txt is advisory, it does not hide pages from search, and it is not a security boundary.
