To me it seems like an even more narrowly subjective focus is being utilized in choosing what is going to be displayed or not. I really think some of this landing page evaluation has been out-sourced a little too much.
What could this be? I hope its only temporary.
I love using the ad diagnostic tool for the search listings, but I noticed there is no such tool for the content network. It seems there is no way to find the reason for these evaporating impressions.
