Frequently Asked Questions
What Traffic Patterns Should I Expect From Yahoo Ad monitoring?
Yahoo Ad monitoring'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.

Not directly. Yahoo Ad monitoring's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.

No special access. Yahoo Ad monitoring can read publicly available pages but cannot bypass authentication. Assume anything you publish openly may be collected.
How Can I Verify a Request From Yahoo Ad monitoring?
Agent Analytics tracks Yahoo Ad monitoring visits in real time. You can also check your server logs for requests whose user-agent string contains "Yahoo Ad monitoring".
