I am at 5.00 for CPM on 500 sites and have not had 1 impression. Anyone know how much you need to bid on CPM ot start getting impressions ?
That obviously means that other people are outbidding you on that keyword. So you have to either bid higher or bid on more specialised key-phrases. Say you were bidding on 'insurance', try bidding on 'house insurance'. More specific should mean less competition.
Keep adding a dollar and you'll soon find the tipping point. Which is also a PITA because once you're "in" you get thousands and thousands of impressions draining your budget in no time so make sure you set your maximum spend wisely - your money can be gone before you realize. I found the treshold to be between $7 and as high as $12 depending on the site.
I agree, find a price where you start to get impressions (using a limited budget) and then slowly reduce the maximum CPM bid as your should still continue to be displayed.
what about site targeting? I have set everything just about as high as it can go, but still no impressions. It was working fine but now nothing. I have the cpm set at 150 which is the highest it can go, and the daily budget set very high, but I still cannot get the ad to show anywere. So what could be the problem.
