was talking to my rep, and he told me something today that I hadn't heard before. the way their bidding system works is that the percentage of traffic you get is tied to the percentage higher you are bidding than the next spot. so, if you are only bidding .001 cent higher, your percentage of traffic won't be much higher. but if you are bidding .02 c higher, your traffic take (and your expenses obviously) will be higher.
I didn't know it worked like that.
Thanks for sharing.
Did they mention how it works exactly? (example: 0.001 higher = 10% more, 0.002 = 20% etc..)
Ahh cool i didn't know this either, i wonder if it's like that for most of the traffic sources.
cheers southbound, great info. So this really changes the placement bidding game! I'm gonna have to adjust my old strategies and test this out.
Never heard of this before. Thanks for sharing 
this explains a lot. awesome share. thanks southbound
