you can't measure the value of a an ad on a message board or resource site in clicks. it doesn't work that way. you advertise to get your name out there and into the minds of your market. clicks and referrer stats can't accurately measure that.
you want your ad to reach as many adult webmasters as possible so, you consider resource sites with an eye on the amount of visitors it gets each day/month/year.
for instance, Cozy Frog gets an average 2500 unique visits a day and around 6000 daily overall. GFY gets fucking 35,000 or some shit like that.
