After seeing questions about % web font usage on https://github.com/HTTPArchive/almanac.httparchive.org/issues/902 I tried to answer via bigquery and wound up with this after rviscomi kindly fixed my initial query
The original question was in terms of site. This answer is in terms of page. Defining site seems a little awkward. A host or domain might have many things a user would think of as a site, and what a user thinks of as a site might have many hosts or domains. I’m curious if there is a definition of “site” httparchive uses?
