Google’s own crawler documentation describes Google-CloudVertexBot as affecting “crawls requested by site owners for building Vertex AI Agents.” Unlike Googlebot or Google-Extended, this crawler acts on a specific site owner’s own request, rather than a general web-wide sweep.

Why this is categorised as “agent”

Google’s documentation frames this crawler around a site owner’s own request to build an AI agent against their content, which fits CrawlPact’s registry’s “agent” purpose category more than a general search or bulk-training crawl.

Site-owner controls

Disallowing Google-CloudVertexBot prevents crawls performed specifically because a site owner (not necessarily you) requested that a Vertex AI Agent be built against this content. It does not affect Google Search indexing (Googlebot) or the generative-AI-training opt-out (Google-Extended) — this token governs only agent-initiated, request-driven access, not a general web-wide crawl. See /limitations for what a robots.txt rule can and cannot guarantee.

Example robots.txt configuration

To disallow Google-CloudVertexBot specifically, without affecting any other crawler:

User-agent: Google-CloudVertexBot
Disallow: /

If no dedicated User-agent: Google-CloudVertexBot group exists in a domain's robots.txt, this crawler falls back to whatever the wildcard User-agent: * group says (RFC 9309) — see robots.txt syntax basics for how group selection works.

Analytics preferences

CrawlPact uses optional Google Analytics and Microsoft Clarity on public marketing pages to understand which content is useful and how visitors actually use it. Neither is used in the authenticated app or admin areas. You can accept or decline analytics without affecting the service.
