A WebmasterWorld member is disgruntled with Microsoft adCenter. Ever since his ads were optimized, adCenter stopped displaying them. He writes:
I have been running some campaings for 2 months. When I started optimizing bids my ads stopped being shown on msn and live. I have no impressions at all.
Rep says my site is not banned, but I need to change ads and increase bids which are not copetetive.
My bids ARE competetive, I change my ads I still have no impressions or just a few while before I had thousands and CTR apx 2%.
Unfortunately, he's not alone. Another member dropped adCenter in favor of Google.
They did the same to some of my accounts. I just pulled all my own and my clients' accounts out of adCenter and shifted the budgets back to Google - nine accounts in all - I don't have time for this, and the returns haven't been worth it.
It seems that while the same thing may happen on Google. Google's AdWords representatives tell the advertiser that they have to raise their minimum bid prices so that they get better traffic.
And all of these advertisers comply -- because they get a lot of traffic if they do.
The difference, then, between Google AdWords and Microsoft AdCenter is that the subscribers are willing to pay top dollar for Google's traffic. They can't say that they will get as good traffic from Microsoft, so they just drop Microsoft instead.
