The FDSE advertising system keeps track of impressions. Impressions count the number of times an user has seen the ad since a certain date.
Other important reporting information, like click-through rates and ad revenue, are the responsibility of a Pay-Per-Click company.
If you are partnering with advertisers directly and do not have a Pay-Per-Click company, you should acquire some general banner advertising software to keep track of reports. Fluid Dynamics does not provide such software; it may be acquired at the CGI Resource Index.
