Definitely not a drop in Yahoo PPC impressions yesterday, actually higher than normal for a Monday.

Bing is hard to compare apples to apples in terms of impressions, because we turned off most off of Bing Content Network in preparation for the transition. Bing clicks may have been slightly higher than average for a Monday.

I think it is going to take several days of data to see what happens. I hear they will transition more traffic over on Friday.
