Frequently Asked Questions
Should I Block Google-CloudVertexBot?
No, for the same reason you would not block Googlebot. Google-CloudVertexBot indexes your site for an AI search engine, and its results link back to you. Blocking it removes you from a whole search channel without helping your traditional rankings. For comparison, 6% of the top websites we track already have robots.txt rules for Google-CloudVertexBot.
Does Google-CloudVertexBot Follow Robots.txt Rules?
Yes. Google-CloudVertexBot is expected to follow 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 Google-CloudVertexBot actually follows it.
Does Google-CloudVertexBot Access Private Content?
No. Google-CloudVertexBot indexes what an anonymous visitor can load, like a traditional search crawler. The bigger risk is content that is public by accident, like a staging site, which it will happily index.
Why Is Google-CloudVertexBot Visiting My Website?
Google-CloudVertexBot is indexing your site so your pages can appear in its AI search results. It found you through links, your sitemap, or mentions of your domain, and it returns on its own schedule to keep the index fresh.
How Can I Tell if Google-CloudVertexBot Is Visiting My Website?
Agent Analytics tracks Google-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 "Google-CloudVertexBot". Look for recurring visits spread across your site, like a search engine crawl. Keep in mind that Google-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.
