I have some old sites with legit content that have pr0-pr3, with over 30 pages of content and moderate traffic. Nothing over a 10% bounce rate and the average time on site is a little over 2 min for the keywords I have targeted. These sites sit on a dedicated ip. Now, I have a handful of garbage sites (less than a year old) on shared hosting all of which I have spun next to non readable and have thousands of pages of content. PR5 and 6. Spammy backlinks, you know the drill. Does anyone know a sure shot method to gain a higher pr? Or does pr really carry much weight these days?
