The stats are sometimes registering a 50-200% click difference. This is too much of a difference to just be clicks from current day (I'm seeing stats on the campaign summary page that a particular campaign has 2000 clicks for a week and 100 for a day, when I check that campaign, the total says 1500 clicks for the week and 75 for the day, (60 being from one adgroup), if I click on that adgroup, I'm seeing that it has 12 for the current day and 500 for the week.
Has G implemented some sort of new fraud checking method that is causing the stats to be vastly different in the various areas?
