Because generalized Internet search encompasses any and all human interests. The vast gulf could easily be explained by bias in what 2 ppl are interested in and search for. For example, if Alice is very interested in Sports News, coding, and movie reviews, they might get great results. And then Bob runs searches on cooking recipes, interior design, and music, and gets terrible results. Most likely you care about something that the other person doesn’t, biasing your search results greatly.
