What i'm seeing in the electronics/consumer side of keywords that the CPC listed is far from the real cpc needed to get impressions. Its almost like the numbers are "smart priced" where statistically speaking you MAY get that price eventually but no matter how long or short you make the historical views go the CPC numbers don't reflect the immediate pricing.
By that i mean if i run the analysis and see the CPC for specific keywords as being .39 cents with a historically good click through ratio and i bid .39 cents i get a big fat ZERO impresions.
If i bid 1.39 for number once spot i start paying a 1.39 and i have no idea how long Adcenter thinks i should pay a 1.39 before it realizes my ad is quality and my ctr is good enough that it can price me more affordably to that magical .39 cents i see in the excel data you provide.
make sense?
I guess on the flipside if i make all my campaigns at those cpc rates and just let them sit will adcenter eventually increase the display of the ads or try different algorithms to get them showing and making you (and me) money?
