Just wondering how long I should keep a high PR link that I'm paying for live. I've read somewhere that 3 months is enough for G to stick that juice to your site. After I take it off will I lose the ranking though? What are your opinions. Also it's a PR8 with 19 OBL and it's almost $500 a month. Should I rely on just that one PR8 or should I use that money to buy a bunch of pr6's and pr5's?
