Maybe you ignore it, but Google has stated in the past that click-through rates with AI overviews are way down. To me, that implies the 'user' read the summary and got what they needed, such that they didn't feel the need to dig into a further site (ignoring whether that's a good thing or not).

I'd be comfortable calling a 'user' anyone who clicked to expand the little summary. Not sure what else you'd call them.
