What is your experience with adwords?

I am noticing many high profile sites offering adwords. Can this be a lucrative endeavor? Do you know of any examples or case studies on this topic?

You probably mean ADSENSE?

In fact it's rather profitable, especially if your website is dedicated to a competitive business and get 1K+ daily visitors.

I'm not sure about mortgages, but I think that it's quite competitive field, and businesses are ready to pay well for being listed in adwords/adsense. The more money they're ready to spend, the more profit you can get by participating in adsense program.

I agree adsense is good--especially cause its free.
