How much can you make running Google AdSense?

The answer to that question depends upon three factors: 

1.How much traffic your site draws 

2.How many visitors click on your ads 

3.How much those ads pay per generated click 

With some ads paying as much as $5 or more, it’s possible that you can generate a serious income with AdSense. There are relatively well documented cases of some people earning as much as $500 per DAY and more. Numbers like that are rare exceptions however. Even so, there is no reason why you can’t earn somewhere around $1,000 per month, or more, once you get the hang of it.
