How much does Google make per month on internet advertising?
According to thier last Annual Income Statement in 2006 they had a net profit of $3,077,446,000. So it would be $256,455,500 a month. They claim that 99% of thier income is from advertising revenue. So I would assume that they make about $254,000,000 a month from advertising. Most of which probably comes from AdWords & AdSense.
