Is anyone having knowledge if a rating system can influence the SE ranking of your website. I see that for the keyword I'm testing some of the websites who ranked high in the first page have a meta tag: <meta http-equiv="PICS-Label" content='(PICS-1.1 "http://www.classify.org/safesurf/" L gen true for "http://www.......com" r (SS~~000 1))'> or something similar from another rating service ???
No i think no.Search engines pay more attention towards content and page popularity than these kind of rating system.
