the worst thing is that i can never see the ad copy when i'm viewing my keywords and vise versa. It would seem to be a simple thing, yet, no matter how many web surveys or phone surveys or adcenter reps I've talked to at SES, etc it never seems to happen. I NEED to be able to see the two together.
Secondly, the performance metrics have NEVER been even close to the actual results. It makes the 'anticipated' data less than reliable and as a result I rarely rely on adcenter for promotional or short term campaigns. Actually, I should say I never rely on adcenter for those types of campaigns.
Probably the most time consuming is having to go through each ad group and turn on/off the content network! Make it a campaign option!!!!!!!!!!! One click and done. That way I don't have to go through each ad group and wonder if I remembered to save each one!
Those are a few of my pet peeves about adcenter. The 'save' feature needs a post of its own!
