CrUX is not ranked. You can join the URLs in HTTP Archive with old Alexa datasets (see [Getting domain rank with the new rank-less Chrome UX Report corpus](https://discuss.httparchive.org/t/getting-domain-rank-with-the-new-rank-less-chrome-ux-report-corpus/1444)) but the Alexa dataset only provides ranking at the domain granularity\*.

About 2/3 of the domains in CrUX are also found in the ranked Alexa domain list.
