I have a campaign that was originally set to $70/day. When I checked it, it said "budget is ok". Except that my client noticed his ads weren't running, and called up to ask why not. This was about 2pm in the afternoon. I checked the campaign, and it was at about 85% of daily budget. I ran the recommended budget tool again, and it still said $70/day was ok, but since things weren't running, I upped it to $120. Three hours later, the words weren't running again. I checked the account - we were at 92% of budget for the daily. Recommended budget still said ok. I then upped it to $200, and it stopped running ads about 10:00pm or so, because I was maxed out for the day. This has been going on for three days now. I haven't noticed too many problems on my other campaigns, but this one is particularly important (and competitive) The recommended budget tool is still telling me that $70/day is a good number, but $200/day isn't even taking me through the whole day. So am I misunderstanding how this tool works, or is there some problem somewhere?
