Today I have found that all my adgroup stats for today say zero, even twelve hours into the day. The updates seem to be getting later and later.
We do take special precautions when setting up new high volume campaigns to make sure they do not get stopped by G before we get to see the stats.
Care to share any precautionary tips?
Having a high volume keyword slowed or at risk before the stats are even updated is one of the most annoying aspects of AdWords.
To avoind being stopped we "phase in" high volume stuff by first using exact matching and making 3 different ads with Google's ad optimization turned on (we normally switch this off asap).
This makes sure your get the max CTR and you can test the waters before the KW is stopped.
I have no hard data on it but also get the idea that multiple ads delay the moment a keyword is stopped as if the algo wants to have some time to get it right.
