What is CriteoBot?

CriteoBot appears when a site asks Criteo to deliver an ad and Criteo needs a current category for the page. The crawler reads public content, then labels the page for contextual advertising. Criteo's own example places an article about running shoes under sport and running.

The crawler does not need to fetch a URL for every ad request. Criteo says it returns when an existing classification is unavailable or out of date. It reads the published page, while data about the person viewing that page is outside this crawler's stated scope.

Requests use CriteoBot/0.1 and include a link to Criteo's crawler information. The operator publishes current network ranges and gives site owners robots.txt rules for allowing, limiting, or blocking access. Crawl-delay is supported up to 30 seconds, including decimal values.

The categories produced by CriteoBot are for ad placement. Criteo does not document the crawler as a source for AI answers or model training. A block can deprive Criteo advertisers of page context, but allowing the bot has no stated benefit for AI search visibility.

Not relevant for AI search

Is CriteoBot relevant for AI search?

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

CriteoBot 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 CriteoBot

If Criteo ads run on your site, keep the pages carrying that inventory available for classification. Use path rules for account screens or other sections that do not need ad context.

Criteo documents this full block:

User-agent: CriteoBot/0.1
Disallow: /

A Crawl-delay or a narrow disallow may solve a load problem without removing all contextual data. For stronger verification, compare the source with the ASNs and address ranges currently listed by Criteo.

Examples

  • After an article changes topic, a publisher sees CriteoBot return and refresh the category used beside its Criteo ad inventory.
  • A site excludes `/profile/` from `CriteoBot/0.1` and sets a modest crawl delay, while its public articles remain available for classification.
