2 questions... 1. is 95%+ uniqueness ok for tier 1 content? 2. Also, , I have less than 30% uniqueness for some of my tier 1 web 2.0 content. I've already link built for it and it's aged some for 3+ months and some of them have PA 35+. Is it better to just disavow that or replace the content? The web 2.0s are already indexed in google.
