And, that those recommendations point directly to the very page that has that information resulting in a satisfied user who does not browse further but goes directly back ‘home’ (to their social network).

I see this regularly on two sites where a visitor coming from a SE search, lands on a relevant page according to their search term(s) and moves on again.
OK there can be an explanation that it was not the exact widget they were after but on that page there is also a clear link to more related pages which they do not follow and check out which makes me wonder if a percentage of internet surfers actually knows that a site usually has more than one page that they can browse.
