Without analytics it is impossible to know how effective your ads are. The Banner Ads Manager allows you to create and upload banners for advertising.  Whether you place the ad on your site or on another the ad will track click throughs and impressions.  There are reports as well for you or your advertisers to see how the ad is performing and also see revenues generated. The dynamic ads also have the ability to track source motivation codes and carry them through to your Donation Processing Center.  This way you know where your new names and revenues are coming from.
