and charge for banner advertising per impressions (eg. 5.00 per 1000 impressions). Is it standard to show data charts to your advertisers on a regular basis (monthly) showing the activity of their ad? If I was an advertiser I think I would want to see the data but as the owner of the directory that would get to be a pain in the ass to do that on a regular basis for hundreds of advertisers. Or perhaps there is a way to streamline that I'm not thinking of?
