Why Is CloudVertexBot Visiting My Website?
Your content matched the criteria Google set for a training dataset. CloudVertexBot typically discovers pages through external links, sitemaps, and seed lists rather than because someone selected your site individually.

Block CloudVertexBot if you want more control over whether your work is used for AI training. Allowing it may increase the chance that your brand appears in AI-generated answers, but either choice leaves traditional search rankings unchanged. For context, 8% of the top websites we track currently have robots.txt rules for CloudVertexBot.

Frequently Asked Questions
What Traffic Patterns Should I Expect From CloudVertexBot?
CloudVertexBot tends to make broad, high-volume sweeps across many pages. Timing is unpredictable: traffic may remain heavy throughout a collection pass, then stop entirely.
Does CloudVertexBot Follow Robots.txt Rules?
CloudVertexBot is expected to follow robots.txt rules, so a disallow rule is the appropriate first step if you want to block it. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether CloudVertexBot respects it.
Is CloudVertexBot Used for AI Model Training?
Yes. CloudVertexBot collects web content for use in AI training datasets. Blocking it limits future collection but cannot remove content that was collected previously.
Does Blocking CloudVertexBot Affect AI Search or Citations?
Not directly. Blocking CloudVertexBot limits collection for AI training rather than controlling a live AI search index or citation system.
Does CloudVertexBot Access Private Content?
Not through legitimate access. CloudVertexBot primarily targets public content, but some training-data scrapers also attempt to collect gated or paywalled pages. If content loads without authentication, assume it can be collected.
How Can I Verify a Request From CloudVertexBot?
Agent Analytics tracks CloudVertexBot visits in real time. You can also check your server logs for requests whose user-agent string contains "CloudVertexBot". Look for high page counts, short gaps between requests, and deep traversal through linked content. Because CloudVertexBot does not publish a verification method, any client can claim its identity and a log match is only a clue.
