In the toilet doesn't begin to describe how bad the stats have been since mid December. This isn't normal, as in it is statistically an outlier. Something is up. I checked my stats for three years back and sure there is a certain degree of seasonality at play but this is not that. Page RPM has been cut almost in half from the first half of December compared to the second half. I have seen drops, 10%, 25% but not 40 to 50% (50% drop == was $2 is 1$.) as I'm seeing this year.
Coverage was an issue around the 18th, but the coverage came back but the earnings remain weak. So I'm really at a loss. Note that my traffic has been strong over this entire period, up near record levels.
The only thing I am seeing that really stands out is that the CPC impressions took a nose dive on the 18th with a drop of 50% and CPM bids doubled over the same period. On the 26th, CPC bids recovered to some extent, but CPM remained high (I assume that this accounted for the recovery in coverage).
So what's up with that? Is this shift from CPC to CPM here to stay? This smells of the issue we had few month back with the un-clickable ads (zloan an co..). Adsense seemed admit to some sort of a bug. Is this the same?
An admin have seen broken ads in Chrome thoughout the day. Might be him only. Anyone know the reason behind it? Looks like a document with a sad face in the spot for the ad. First it was for some positions, not all of them.
