Weird revenue per 1000 visits

On my site globalicwarming.com the revenue is 20$ per 1000 visits but On my Handlemistakes.com it is 1,3$ per 1000 visits, seems like I want to buy some adsense for the globalicwarming site

 

edit: adwords, not adsense

 

Hi there - I'm a new poster but long-time reader and fan of this forum.

To add my bit to the thread, we just added AdSense to a few of our pages to test it out.
Made the first $5 between Monday and Tuesday with only 183 hits one day and 73 the next!

I cant explain it and hope somebody could - how is AdSense calculated?
I've read plenty of threads here but I'm still confused.

 

Adsense is calculated per click .. 50% goes to google n the rest comes to u (appx) from what advertisers bid for. Ther may be many advertisers for the same jeyword and that's the primary reason for variations in earnings..

 

50%?? Are you sure?

 

Its 78% in favour of the webmaster and the rest to Google.

 

Infact, the actual figures are never disclosed..

 

That's what i thought, but 50%? 78%?
It all sounds so high.
I was making my calculations on no more than 10-20% tops...

 

The NYT recently quoted the 78% figure.

 

i read somehwere that it's between 40% - 60%. but google doesn't disclose the actual figure, so we can only speculate.

 

my guess would be in the 20-30% range
