...how is that broader user experience determined and then injected back in as a ranking factor;
The discussion is about how Google measures quality. To make an analogy, an actor is put through rigorous auditions before being hired. Then they are put through rehearsals prior to making it to the stage. The substance of the work happens BEFORE the actor reaches the stage. If you want to have a meaningful discussion about quality, then you have to go way back before the actor reaches the stage.
The title of this discussion is about quality. Much of the action happens BEFORE the SERPs are displayed. If you want to discuss what happens AFTER the SERPs are displayed, the injection back into the algo is likely to be as feedback about the parts that happen before the SERPs get displayed, but not necessarily as feedback about the quality of the site itself.
1. The methods designed to select for trusted non-spam sites failed.
2. The methods designed to weed out untrusted spam sites failed.
3. A query was improperly answered.
Those are all issues with the algo that happened before a user backs out of a site because of dissatisfaction. So if that gets injected back into the algo, it's going to get revised either at the inclusion point, at the point of exclusion, at the user intent level, or at many points together in order to scale the solution.
Do SERPs bounce around. Yes. But I don't think the algo is targeting one site at a time like the gods on Olympus. That's too simple.
