Glossary

The vocabulary of AI traffic, written out.

59 crawlers explained at length — how each behaves, how it is verified, and what allowing it actually costs — plus 12 entries on the ideas underneath: forward-confirmed reverse DNS, spoofing, zero-click, cookieless measurement.

Looking up a token you found in a log? The crawler directory is the short answer.

  • AI crawlers

    The bots themselves — who sends them and what each one fetches for.

  • Verification

    How you tell a real crawler from something wearing its name.

  • AI visibility

    Being read, cited and found by assistants rather than by search.

  • Analytics

    Measurement terms — sessions, attribution, and what they leave out.

  • Privacy

    Cookies, consent, and what a measurement product should not collect.
