So a site I manage that is over 200 million page views a month was affected by the recent text ad format change by AdSense. We are one of the publishers no longer serving the grey arrow versions. They worked incredibly for us, but that's over..time to move on.
Now looking at the performance data, I have made our campaign all rich media/image ads...no more text ads. Before, we were very happy and ran text ads almost exclusively. Now I am thinking if I am going exclusively rich media/image ads, perhaps it is time to consider another ad network than AdSense. Given such high traffic our site is, AdSense seemed liked the best option, but now that texts are out for us perhaps there are better options/approaches.
Appreciate your thoughts.
