I'm looking to advertise my new 468 X 60 banner and I noticed that there are offers for different PR# sites. What is PR1 - 7 (I'm not even sure how high they go up) and which sites get more traffic?

Thanks

Pagerank. Google has more info here - http://www.google.com/technology/

The higher the number, the better

EDIT: More detailed info here - http://en.wikipedia.org/wiki/PageRank

Thanks for the response and those links. So how high can the pagerank go (ie. what number does it go to)?

Thanks

Up to 10 (10 being best)
