I found the mendoza line for Adcenter today. I lowered the bulk of my minimum keyword bids a mere .05 cents and traffic stopped like it was driving through Atlanta. That nickel made a good difference when it comes to clicks. It definitely shows me more proof that you have to play around with your minimum bids. It is one thing to read that and hear Shoemoney talk about it on his radio show at Webmaster Radio it is completely different to see it and feel it in action. The difference between paying out .05 or .10 cent may not seem like much now, but the difference between paying $500,000 and $1,000,000 is a nice beach house.

Edit: As a slight clarification, my bids are more than the 5 or 10 cent example I used. I picked those numbers to keep it simple.
