I'm seeing the same thing, I was just about to post this question before I noticed Lloyd's question:
I'm getting zero values via the API for:
- AveragePageviews
- AverageTimeOnSite
- BounceRate
- PercentNewVisitors
in a AD_PERFORMANCE_REPORT. According to the Reports Reference documentation these columns are available and I don't get an error in my report submission, just zero values.
This is happening across multiple clients where I previously had values and the data disappeared on 9-10 December.
This doesn't appear to be a time lag issue as I've tried re-importing the whole of December today and now I have no analytics data since 30 November!
Is anyone else experiencing this? Has anything changed in the way analytics data is integrated into AdWords reporting?
Just to reiterate, I was getting analytics data with no problems prior to 9/10 December and my report definitions have not changed.
Cheers
David
