CPC related to earnings per click?

Is the average cost per click for advertisers calculated for the keyword "computer" here:

https://adwords.google.com/select/TrafficEstimatorSandbox?save=save&keywords=computer "computer"

which shows as $2.44 average CPC relate to how much the publisher gets as earnings per click?

I read somewhere that it is near 50 percent, but that seems way, way high

 

Not sure anyone knows, I seem to recall reading something a few months ago that publishers got something like 75% of the revenue of a click from Adsense, which seems pretty high to me but may be true.

I have a computer related site and it often gets $2 or $3 dollar clicks, so I would guess the percentage to publishers is pretty high.

 

I think it would be quite high too, all google needs is a small amount of this revenue and that's how they make billions

 

dang wayner those earnings must be nasty with some traffic

 

if this is trrue why do people get terrible earnings per click? Their niches can't be that bad...

 

I'v read that they do take 75% of that average CPC. So you will mostly like get 25% of what the average CPC for that keyword.
