Impressions in SearchQueryPerformanceReport is much smaller than the one in KeywordsPerformanceReport

[Jay Zou]

I downloaded both SearchQueryPerformanceReport and KeywordsPerformanceReport from API. Both reports use the same date range.

Selected rows associated with one keyword, I found the aggregated Impressions in SearchQueryPerformanceReport is much smaller than the one in KeywordsPerformanceReport, like 526 vs 361,468.

I used 'Keyword ID' field in both report to select rows. 

Did I do something wrong or they are supposed to be different?

Hi Jay,

In the Search Query Performance Report, you’ll only see search terms that were used by people at least 8 hours ago and have either received clicks in the past 30 days or were searched for by a significant number of people. Any search terms that did not meet this criteria will be summed up in the 'Other search terms' row. This might be the reason that the stats from this report differ from Keywords Performance Report. More information about the Search Query Performance Report is provided here. 

I hope this helps.

Thank you so much, Shwetha. That resolved my confusion.
