Why track BinaryCanary traffic?

Distinguish monitoring traffic from real crawler activity. BinaryCanary checks your site availability at regular intervals. Without proper identification, these requests can inflate your bot traffic metrics and distort crawl analysis.

Validate monitoring coverage. Track which pages BinaryCanary checks and how frequently, so your monitoring setup matches your infrastructure requirements.

Log Verification

To verify BinaryCanary traffic in your live traffic data:

  1. Search access logs for the user-agent strings listed above
  2. Check if the IP addresses match documented ranges (if provided by Binary Canary)
  3. Verify the crawl pattern matches documented behavior
  4. Use reverse DNS lookup for additional verification if available

Note: Observed behavior in production environments may differ from official documentation. Live traffic monitoring provides the only reliable verification of actual bot behavior.
