What is viberank?
Directory/review crawler for AI agent products. Agent crawlers browse the web on a user's behalf inside AI tools: opening pages, reading documentation, and completing tasks. Traffic arrives from engaged users who asked for exactly what you offer. Blocking agents does not protect content from training, but it does cut off this kind of high-intent visit.
Allowing it keeps your site reachable to AI agents acting for users — an emerging traffic channel worth keeping open.
Does viberank respect robots.txt?
Yes. viberank honors robots.txt directives, including wildcard rules and Allow lines. A Disallow rule for this crawler is respected — but remember robots.txt is a voluntary protocol across the whole industry, not a wall.
How to block viberank
Add this group to your robots.txt to deny viberank across your whole site:
User-agent: viberank Disallow: /
Blocking it stops agent-driven visits but provides no real content protection, since agents only fetch pages the user asked for.
How to allow viberank
viberank is allowed by default on every site. It only gets blocked if a matching rule exists — most often a global User-agent: * group with Disallow: /. To exempt it while blocking other bots, put an empty Disallow group for it before the global block:
User-agent: viberank Disallow: User-agent: * Disallow: /
Does blocking viberank hurt your rankings?
No — not for classic search. viberank is not a Google user agent, so a robots.txt rule for it has no effect on Google rankings or indexing. The only thing you give up is what this specific AI agent browser does with your pages, described above.
How to verify viberank is really hitting your site
robots.txt states what a compliant crawler may fetch; your access log shows what actually happened. Search the log for the token:
grep -i "viberank" /var/log/nginx/access.log | tail -50
On Cloudflare the free plan does not expose raw request logs, so use Security Events to see blocked requests, or add a console.log line in a Worker to record the user agent. On Vercel or Netlify, filter the request log by user agent string.
User agents are trivially spoofable, which is why "I saw viberank in my logs" is not proof. Because viberank is documented to honor robots.txt, a request from it that ignores your rules is worth investigating — but a single stray hit is usually a misconfigured tool, not the real crawler.
Should you block viberank?
- Allow it — agent traffic is a user asking an AI tool to do something on the open web, which is closer to a real visitor than a crawler is.
- Block it if the agent could trigger writes, purchases or state changes on your site, and you cannot tell agent traffic apart downstream.
- Expect growth here — agent browsers are the newest category and the least covered by classic bot management.
