When I first started using Adcenter, the bid prices where not that bad compared to Google.
Lately, In adcenter I'm seeing bids that go for 20 to 30 cents on Adwords, demand 50 cents to 1 dollar before they even start showing them.
Take note adcenter, you have a chance to capture a lot of disgruntled adwords advertisers, but pulling bids out of your orafice just because you think people will pay is really not smart.
I will instead spend more money with Adwords since I will get more clicks for every dollar spent.
Everybody always talks about Adcenter being an alternative to adwords but that is just not the truth and once they power Yahoo, there going to be worse than Adwords to deal with.
