I dont Understand google...

[olhos-nos-olhos]

Hi!
I dont i dont understand the way google works!
From jan 2006 to Nov 2006, I had in my site about 700~1000 unique visitors and google's return was about 1,50~2,00 USD. ok!
In Dec 2006, I had in my site about 1500~2000 unique visitors and google gave me the same 1,50~2,00 USD!
In Jan 2007, I had in my site about 2000~2700 unique visitors and google gave me the same 1,50~2,00 USD!!
This month ( Fev 2007 ) I have in my site abou 3000~4000 unique visitors in my site. Do you know how much google give me? The same 1,50USD~2,00USD every days!!!
Why? What's wrong whith my site?
I did not change my google's adsense codes, nor the positions of my adsenses, nor the colors! Nothing.
The only diference is that I have now about 4000 unique visitors and in Jan 2006 I had about 700 but google pay me the same 1,50USD~2,00USD every days!
What do you think about this?

No, I'm not. Should have?

700 unique visitors is the same of 4000 unique visitors for you? 2 USD for 700 and 2 USD for 4000? Sorry but something is not ok...

Someone else can really help me? I just dont understand the criteria. I did'nt change nothing. Is not it rare?

If you give the URL of your site, I may review it in detail and may let you know what's going on wrong, coz with 7000 Unique visitors a day, you MUST earn, atleast $25 a day.
