Frequently Asked Questions
Should I Block Google-CloudVertexBot?
Usually not. Blocking Google-CloudVertexBot keeps your pages out of its AI search results and can eliminate referral traffic from that channel. It does not improve traditional search rankings. For context, 7% of the top websites we track currently have robots.txt rules for Google-CloudVertexBot.
Does Google-CloudVertexBot Follow Robots.txt Rules?
Yes. Google-CloudVertexBot is expected to follow robots.txt directives, so a disallow rule is the appropriate first step. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether Google-CloudVertexBot respects it.
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.
Why Is Google-CloudVertexBot Visiting My Website?
Google-CloudVertexBot is updating an AI search index so your pages can appear in its results. It may have discovered your site through links, a sitemap, or mentions of your domain.
How Can I Tell if Google-CloudVertexBot Is Visiting My Website?
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.
