You can hold all your advertising codes into a single xml, then place this control (or many instance of this control) where you want on the page, link it to the xml and select what you want to show. Each Advertising control can shows the units in 3 modes: - random: a unit will be randomized between all the units contained in the xml. - filtered: a unit will be randomized using one or more filter (width, height, group of the unit or group of the vendor). - exact: you indicate exactly what is the unit you want to show. Each unit can contains html code, flash or js script and works fine with Google AdSense or any other marketing company.
