so my site ranks #20 and has significantly higher PR compared to others that rank higher. i have more backlinks (high PR, edu/gov, etc), more links from unique domains. None of us is in DMZ. 2 of them are in yahoo dir. only one of them has significantly more indexed pages. my age is 1 compared to their 2,3, 8, etc. with all that, i am #20? what can i do now?
