Frequently Asked Questions
What Traffic Patterns Should I Expect From Google-CloudVertexBot?
Google-CloudVertexBot revisits your site on a flexible schedule, often requesting several pages in a burst. Activity usually increases when your content changes or its index refreshes, with quiet intervals between crawl passes.
Does Google-CloudVertexBot Follow Robots.txt Rules?
Google-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 Google-CloudVertexBot respects it.
Is Google-CloudVertexBot Used for AI Model Training?
Not ordinarily. Google-CloudVertexBot is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking Google-CloudVertexBot Affect AI Search or Citations?
Yes. Blocking Google-CloudVertexBot can keep your pages out of the AI search index it supplies, reducing their eligibility to appear or be cited in that product's answers.
Does Google-CloudVertexBot Access Private Content?
No special access. Google-CloudVertexBot can reach only content available to anonymous visitors. Make sure staging sites and other sensitive areas require authentication.
How Can I Verify a Request From Google-CloudVertexBot?
Agent Analytics tracks visits from Google-CloudVertexBot and every other known AI agent, crawler, and scraper, then authenticates each visit using Google-CloudVertexBot's published verification method. You can also check your server logs for requests whose user-agent string contains "Google-CloudVertexBot". Look for bursts that follow links across several pages and recur over time. A matching log entry alone is not proof because any bot can claim to be Google-CloudVertexBot.
