Welcome to WebmasterWorld Guest from 220.127.116.11
Anyhow, I've been looking at one site in particular that has overtaken me. They use the following tags in their html:
content='(PICS-1.1 "http://www.classify.org/safesurf/" l r (SS~~000 1))'>
content='(PICS-1.1 "http://www.rsac.org/ratingsv01.html" l r (n 0 s 0 v 0 l 0))'>
I cant see how, but would this possibly increase page rank in any way? This site has a PR6, and I cant see how from looking at their backlinks. This is the only thing that caught my eye that they appear to do differently.
