In my case, yes it does.
I get about $130 every three months which more than pays for the hosting of the website...
Here are two days worth for my website.
Sunday, February 1, 2009 760 7 $2.29
Monday, February 2, 2009 1,000 10 $0.80
So basically I got 760 page view, 7 clicks of an ad, so I got $2.29 for that day.
Compared to 1,000 page views, 10 clicks for only $.80 on Monday.
The price difference comes down to exactly which ad was clicked. Some are worth more than others.
I'm sure I could do more to maximize profits, but I'm pretty happy with what I get for the service I provide.
