This example custom rule challenges requests from a list of countries, but allows traffic from search engine bots — such as Googlebot and Bingbot — and from other [verified bots](https://developers.cloudflare.com/bots/concepts/bot/#verified-bots).

The rule expression uses the [`cf.client.bot`](https://developers.cloudflare.com/ruleset-engine/rules-language/fields/reference/cf.client.bot/) field to determine if the request originated from a known good bot or crawler.

* **Expression**: `(ip.src.country in {"US" "MX"} and not cf.client.bot)`
* **Action**: *Managed Challenge*
