Since the end of February my adsense earnings got lower and lower. And at this stage I need to do something about it because the earnings are getting way to low.

I decided to try Google DFP small business. This way I would like to a/b test several ad positions and variations a lot quicker. For most of the site I’ve added the code but for my forum I do not seem to be able to get the things done the way I want it.

I have three banners (or Ad units). One for the top of my page, one after the first post and one after the last post. I would like to show only one banner at the time to see which position (or Ad Placement) works best. Each Ad unit need to be shown at a specific position to correspond the background colours of the website.

I’ve tried a lot of options to try to accomplish this, but it didn’t work out :) . At this time of the three ads one is showing on the pace bot always at the same spot. I would like this to rotate.

I’ve tried to put all the ad units in the same ad placement, but this didn’t work. Then I tried to give easy ad unit its own ad placement (in the future I would like to show multiple ads for the same ad placeplant).

Anyone who might be able to help me with the settings?
