Google does not disclose exactly how much
you'll earn per ad clicked. The payment you receive depends
on how much advertisers are paying Google for the particular
keyword ad. You will earn a share of that amount.
I've heard of people earning anywhere from 2 cents to
$15 per click.
So it is logical to believe
that the more popular keywords (debt free, money, mp3,
etc.) may earn you more since these are highly competitive
keywords that are searched for quite a bit on the web.
As a result, advertisers generally pay more for these
keywords.
In other words, it would be
to your advantage to create a site that focuses around
the more popular keywords to increase your chances of
earning more for the ads you display.

Even though Google will not
reveal how much you are earning for each ad that is clicked
from your site, you can still login to your account at
any time and see the total amount of revenue you've generated
that day, week, month, year, etc.
How much you'll earn also depends
largely on the amount of targeted traffic you receive
to your own site, how well the ads match your audience's
interests and of course, the amount you receive per click.
Google pays Web site owners
with a monthly check that is sent directly to your specified
address.
Keep in mind, the better
the ads match your content, the more clicks you'll receive.
