Actually the ranking model of google is much more deeper than page rank
which is only the visible part of the iceberg. For most search google
provide quite good results still subject to critics, but still better than
most engines. They not only use link to compute page rank but authority
sites are defined in a way that try to avoid the whole bots things. Still
subject to critics but not so bad.

Exactly what I found too but indeed I found that allow to quickly identify
non relevant pages and sometimes also the relevant ones. I really want to
know how they decide to present such image or not...
