The reason I'm asking is because my impressions have suddenly dropped to 1-2% of what they were over the last couple of day. The CTR on one of my campaigns was over 5% so it can't be a click through rate problem, not on that campaign at least.
The only thing I've done is resume a paused campaign. None of my keywords are flaged, no messages from google, everything should be fine.
I've checked my campaign settings to see if my ads are still being shown nationaly and haven't been reset to regional by accident.
Everything should be fine, but it's not.
