Four days ago I was organizing my adwords account, and I was told that I was reaching my keyword limit so I drastically deleted Keywords that weren't worthy.
For the next several days, my impressions and clicks in the content network have completely went to 0, and I'm getting no traffic although the search traffic is still there, slightly above normal.
My account is setup for invoice payment, and my payment is due soon, but it isn't past due and will be paid on time as it is every month. I received an email today stating my balance that I owed $40,000 but my limit is $50,000.
I did the routine and called google and they said there is nothing wrong with my account but think about it, going from millions of impressions to 0 overnight for several days is mind boggling.
