This is the most complete and configurable ad manager you'll ever need. I use it on more than 10 sites.
Define the properties for each one of your banner areas and set up blocks (for displaying multiple banners on an specific area), groups (to display single rotating-on-refresh banners) and single banners, no matter if they are images w/links or more complex HTML structures.
On of its best features, it's the ability to track clicks and calculate the CTR. You can also create accounts for your clients with an advertiser rol, so they can check out how well their banners are doing.
Of course, you can also program the banners according to dates, clicks or views, and more.
Thank you so much for creating this wonderful plugin!
