They do have citations. They’re just very non-obvious because they’re a 1ch width Unicode character in a little circle. (It’s the “link” symbol.) And clicking it doesn’t take you to the source, but instead opens a side panel where there is a link that will take you to the source (often it’s one of multiple sources in the panel).

And technically speaking, this citation is the first link on the results page, so you “rank” higher than all the other results. But it does take two clicks to get to your page.

They should make the citations more prominent and use the page title as anchor text. And when there’s multiple citations, the side panel should be open by default or they should put all of the citations inline as prominent links with page titles as anchor text.
