How the checker reads websites
The Google and AI visibility check reads a website with a small automated reader called ClickZeroVisibilityBot. If you saw this name in your logs, someone asked for a visibility check of that website on clickzero.co, or we ran one for them. Until October 2026 it was called DaniyalVisibilityBot.
ClickZeroVisibilityBot/1.0 (+https://clickzero.co/visibility-check/bot/)
What it does
- Fetches at most 12 HTML pages of one site, at most 30 requests in total, two at a time, once per check. Checks for the same site are not repeated within days.
- Reads robots.txt first and obeys rules for
ClickZeroVisibilityBot, its earlier nameDaniyalVisibilityBot, and*, including Crawl-delay. - Does not run JavaScript, log in, submit forms, download media, or fetch anything outside the requested site.
- Stops after 45 seconds or 2 MB per page, whichever comes first.
How to block it
User-agent: ClickZeroVisibilityBot Disallow: /
Requests from it will then stop at your robots.txt. The person who asked for the check will see that the site could not be read.

FAQ
Questions about the crawler
Why is ClickZeroVisibilityBot in my server logs?
Someone requested a Google and AI visibility check of that website on clickzero.co, or we ran one for them. It reads at most twelve pages, once, and checks for the same site are not repeated within days.
How do I block it?
Two lines in your robots.txt, shown above. It obeys rules written for its own name and for the wildcard, including Crawl-delay, and stops at the robots file.
Does blocking AI crawlers hurt my visibility?
Blocking training crawlers such as GPTBot, ClaudeBot or Google-Extended does not change whether assistants can find you when they search. Blocking the search crawlers, such as OAI-SearchBot, Claude-SearchBot, PerplexityBot or Googlebot, does. The check reports the two groups separately and never counts a blocked training crawler as a visibility problem.
Does it store my pages?
It keeps the excerpts used as evidence in the report and a log of what it fetched. Reports are private links that expire; the privacy notice says what is kept and for how long.
