What is ProximicBot?

An ad about to be served can prompt Comscore's Proximic crawler to read the surrounding page. The resulting analysis helps advertising partners decide which campaigns fit the page's subject and whether its content is suitable for them.

The crawler downloads public, static text and does not run JavaScript to generate an ad impression. Comscore says the analysis can produce a language, a content rating, and IAB categories. It may also crawl pages in sequence when a partner wants a site-level view, but Comscore says it does not store the page source code.

Current Comscore documentation identifies the client with proximic in a browser-style user agent. That differs from the ProximicBot label used in some bot records. The crawler normally makes about one request each second, honors robots.txt, and supports Crawl-delay. Updated rules can take up to a day to reach all of Comscore's systems.

This activity supports contextual advertising. Comscore does not describe Proximic as an AI search crawler or a source of general-purpose training data. Blocking it may leave advertising partners with less context about a publisher's pages, but it has no documented effect on discovery by AI answer services.

Not relevant for AI search

Is ProximicBot relevant for AI search?

No. ProximicBot is not part of AI search or training, so allowing or blocking it does not change your AI visibility.

ProximicBot fetches pages for ad review, placement verification, or targeting. It does not influence search rankings or AI answers; it only matters for whether ads on that platform run and what they cost.

How to handle ProximicBot

Publishers that rely on Proximic classifications should leave ad-supported content reachable. Exclude subscriber tools, account pages, and other routes that are not advertising inventory with path-specific rules.

Use Comscore's documented token, which is lowercase:

User-agent: proximic
Disallow: /

For excess request volume, a Crawl-delay is more targeted than a full block. Comscore can also send custom authentication headers for publishers that need a safer allow-list than a user-agent match.

Examples

  • An online magazine permits `proximic` under `/stories/` but keeps `/subscriber/` out of scope because ads are not sold on those pages.
  • A publisher that sees a steady request each second sets `Crawl-delay: 2` and checks the logs a day later, after the rule has had time to propagate.
