What is CloudVertexBot?
CloudVertexBot is a Google-operated crawler available to site owners to request targeted crawls of their own sites for AI training purposes on the Vertex AI platform. Agent Analytics can track when it visits your website.

Expected Behavior
CloudVertexBot crawls websites to build AI training datasets, and its operator decides which sites, how often, and how deep it goes. Expect broad sweeps that fetch far more pages per visit than a search crawler would, on an unpredictable schedule. Volume can run heavy while a collection pass is underway, then stop entirely.

Disallow: /Frequently Asked Questions
Should I Block CloudVertexBot?
Block it if you want control over how your work trains AI models. CloudVertexBot downloads your content into training datasets without attribution, compensation, or any promise of traffic back. The case for allowing it is reach, because models trained on your content can surface your brand in AI answers. Neither choice changes your Google rankings. For comparison, 1% of the top websites we track already have robots.txt rules for CloudVertexBot.
Does CloudVertexBot Respect Robots.txt?
Yes. CloudVertexBot is expected to honor robots.txt rules, so a disallow rule is the right first move. Automatic Robots.txt adds and maintains that rule for you, and Agent Analytics confirms CloudVertexBot actually honors it.
Does CloudVertexBot Access Private Content?
CloudVertexBot targets public content, but the boundary is not always respected. Some training data scrapers go after paywalled or gated pages when the operator wants that data. If a page loads without signing in, assume it can be collected.
Why Is CloudVertexBot Visiting My Website?
Your content matched what Google wants in a training dataset. CloudVertexBot discovers pages mechanically, through links from other sites, sitemaps, and seed lists, not because anyone chose your site personally.
How Can I Tell if CloudVertexBot Is Visiting My Website?
Agent Analytics tracks CloudVertexBot visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user agent string contains "CloudVertexBot". Look for broad sweeps that fetch large numbers of pages in sequence. Keep in mind that CloudVertexBot doesn't publish a verification method, so any client can claim its user agent string and a log match is a hint rather than proof.
