Welcome to WebmasterWorld Guest from 126.96.36.199
Removing the US queries of 2,129 from the total of 3,310 leaves 1,181 queries from outside the US, but a whopping 307,500 impressions (versus 60,500 impressions from 2,129 queries)
Ah now I get it. Could I hazard a guess that there is more "nonsense" going on from non-US accounts?
The 3310 includes all queries, both U.S. and non-U.S, but many were duplicated in different countries, so the number 3310 represents unique queries only.
The main puzzle for me is why a large majority of the impressions and clicks are non-U.S. Either the numbers are erroneous or your efforts to mainly target the U.S. aren't succeeding.
