Well we just had an e-mail from a client with server problems. One of the ad groups we run for them has about 60 ad groups in, so we tried to take it down to a daily budget of 0.00 and it said the minimum per day was a penny. Does that mean we will get charged 30p a month? What sort of CTR will we get? (just kidding).
Apologies if anyone else has written about this before, but I jsut thought it might help por souls like me not to have to pause and resume 60 campaigns.
Alternately, you can opt for display of your ads in the frozen wasteland of Antarctica or the deserts of Sahara ;)
