Impressions differ between keywords and search term performance report
Hi, I noticed that the Impressions number between the Keywords performance report is different from the Search term performance report. Can someone explain the differences between what is being counted between the two reports?

I contacted AdWord's rep and resolved the issue.
The discrepancy came in the aggregate reports. When you generate the aggregate search performance report on an individual client basis, you get a catch-all row that is right above the total row for all the impressions that have received no clicks in the previous 30 day period. This catch-all row does not appear in the aggregate search performance report, thus the under counting in the number of impressions between the aggregate search performance report and the aggregate keyword report.
