These companies are spending lots of ad money online

Got your attention? ClickZ has its terribly useful monthly table of the Top 50 Online Advertisers. The top five are: Vonage, University of Phoenix Online, Classmates.com, Cingular Wireless and Ameritrade.

Sadly these figures are based on the impression levels - and don’t take buying models into account.
It assumes all companies pay for advertising impressions - i.e. every time the ad is shown - wheras a lot of the advertisers in the top 5 (if not al of them) will only pay for clicks, or for sign ups.
For example I’m sure that Classmates.com don’t pay every time someone sees one of their ads.
