Frequently Asked Questions
What Traffic Patterns Should I Expect From CriteoBot?
CriteoBot's traffic pattern depends on the intelligence being collected. It may revisit specific pages on a schedule, crawl broader sections of your site, or appear only when information is requested. Its request scope and frequency reflect the underlying objective.
Does CriteoBot Follow Robots.txt Rules?
CriteoBot 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 CriteoBot respects it.
Is CriteoBot Used for AI Model Training?
Possibly, but its category does not establish that purpose. CriteoBot's operator may use or provide the collected content for AI training or for unrelated automated tasks.
Does Blocking CriteoBot Affect AI Search or Citations?
Not directly. CriteoBot's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.
Does CriteoBot Access Private Content?
No special access. CriteoBot can read publicly available pages but cannot bypass authentication. Assume anything you publish openly may be collected.
How Can I Verify a Request From CriteoBot?
Agent Analytics tracks CriteoBot visits in real time. You can also check your server logs for requests whose user-agent string contains "CriteoBot". Traffic may range from repeated requests to the same pages to broader crawls or one-off fetches. Because CriteoBot does not publish a verification method, any client can claim its identity and a log match is only a clue.
