Just an interesting observation. I put Casale's ads on about 20% of my site, and shockingly, the earnings from this, for this month, is almost 70% of my Fastclick earnings, and I have at least 2 Fastclick banners on each page. I've switched the Fastclick Ads with the Casale ads, and will see if my earnings improve as much as I think it will/should. I find this very interesting, because I've always thought that Fastclick paid more. At least this is what I've always heard. Anyone have any thoughts about this?
