Summary

  • Cloudflare defines Verified Bot identity with Web Bot Auth and BotBase cataloging identities.
  • A system will evaluate deviations from the 'do no harm' rule to maintain trust.
  • The system considers robots.txt adherence over time as a trust signal.
  • HTTP 429 responses and observed rate adjustments are part of trust assessment.

Cloudflare’s post on Verified Bots emphasizes that verifying who operates a bot creates accountability, but trust depends on what the bot does next. The article frames trust as something earned through behavior, not just declared identity.

HOW A CLOUDFLARE VERIFIED BOT WORKS (AT A GLANCE)

To become a Cloudflare Verified Bot, operators must identify themselves accurately and securely using Web Bot Auth, with BotBase cataloguing identities in an open format.

SIGNALS USED TO MEASURE TRUST

The system evaluates whether a bot respects site preferences by looking at robots.txt and repeated patterns of behavior that align with those preferences over time.

Signals also include how a bot responds to HTTP 429 (Too Many Requests): slowing down or pausing can increase trust, while ignoring signals can lower it.

  • Robots.txt adherence
  • Repeated pattern analysis
  • HTTP 429 response handling

CONCRETE EXAMPLE: PERPLEXITY DE-LISTED

In 2025, Cloudflare de-listed Perplexity’s bot after it sought resources on sites that opted out of scraping and attempted to circumvent controls.

PUBLIC TRUST SIGNALS AND WHAT READERS CAN EXPECT

Cloudflare indicates trust scores will be published publicly on Radar in the future, alongside Bot Preference Sync and Bot Management tools that help site owners publish preferences and manage automated traffic.

WHAT THIS MEANS FOR READERS

For site owners, trust signals and configurable thresholds may influence whether automated traffic is allowed, slowed, or blocked according to published preferences.

For bot operators, demonstrating consistent, respectful behavior over time can help maintain trust and avoid de-listing.

UNCERTAINTIES AND NEXT STEPS

The post characterizes the scoring and trust-building process as evolving, with an emphasis on sustained behavior over isolated events.
