Is the Co-op network dependant on: (a) views (impressions) (b) click through's (c) accumilated PR (d) mix of the above So, how do I build up browny points? If I have 2 sites, (a) with decent PR and a few thousand hits a week, or (b) very low PR but ten times the above site in traffic. Which is going to increase my points and thereby give me more links on other sites?
