Today, after the last updates, I can tell you that there are sites ranking on short/long tail keywords that they aren't even mentioned once in their pages, nor they have links with these keywords.

These sites are simply considered the best on their topics and Google finds a way to drive them traffic (because they are 'the source of information').
