Multiple Ad Units
Another way to increase ad revenue is to use multiple ad units. According to Google’s TOS you are allowed to post up to three ad units per page. Similar to standard search results the highest paying ad units will be served first and the lowest being served last. If there is enough of an ad inventory, place all three ad units. However you should pay attention to the payouts. Current assumption is you get 60% of the revenue (on a $0.05 click you get $0.03). So if a click from the third ad unit is only paying between 3 to 5 cents you may want to omit it from your page. This is one are where giving your ad units channels does have value. If one ad unit is getting a higher percentage of click throughs you’ll want to make sure the highest paying ads are being served there. TIP:Use CSS positioning to get your highest paying ads serving in the location with the highest CTR.If you are interesting multiple ads unit. Please contact me.
