Where does visits come from ?

In your opinion, if a website has very much visits but has a low Pagerank ( so low visits from google or other sites linking it ), Where does visits come from ?

I know that PR is not related to traffic but PR low means:
low google traffic and low traffic from other websites ( without nofollow link ). This means that the visits come from other places.


This site for example: hardsextube has PR 3 but millions of visits per day

Wrong, low PR sites can still get a lot of traffic from google.

PR does not directly relate to the amount of traffic a site gets...

Ha, I love how your example was a porn site.
