I think you meant AdSense because AdWords is for advertisers and the only way you make money from that is by bringing traffic to your site.
I have several AdSense links on my sites and a couple months ago I was averaging about $50-$75 a day with all of my AdSense campaigns. I wasn't trying to get rich off of it but and extra $2000 a month was pretty good spending money. However, lately I haven't been making SHIT on my AdSense. I've been getting the same frequency of clicks and searches but now I'm only averaging less than a $1 a day. Not sure what happened or why it happened, but I went from roughly $2000 a month to less than $50. I didn't change anything on my sites and everything was totally legit on non-adult related sites.
I haven't had the time to research but I heard through the grapevine that Google has this new smart click (or smart search) feature that is killing the AdSense market.
If you're still interested go to Google.com and the have flash tutorials and everything else you need to get started. Just don't plan on getting rich off it...that's Google's job.
