I admin the forums at http://zindy.zone.dk/forum and I've seen quite a few people here sell banner space based on impressions, however the topic of this site is not one of the big ones like webhosting or SEO but instead art, mainly drawings. As I have never done this before I'd like some input of what prices you think would be fair. I run phpAdsNew and each of the adsense banners that are currently on have recieved an average of 5.941 impressions/day for the last 7 days. Any thoughts to help me get started with this?
I guess selling by month and ignoring impressions would also be a possibility.. any thoughts or experiences?
