I shared my way of making money with adsense on this thread http://www.warriorforum.com/adsense-...tion-less.html

It may give you some idea

The secret is lots of traffic, & a clean looking site.

Look into XFactor and Clickbump ...micro niche sites - I'm making a boatload with Adsense, and they are too.

Adsense sites are well worth it, you just need to patience to devote your time to them and before you know it you'll be banking.

I don't know. We use to make allot compared to what my parents made their whole life. Now we're in the $4000-$5000 a month range.

I make $ 35 a month, planning to do 2 more sites so that it will go up to $100 a month.

Basically you need a good amount of informative content, using well-chosen keywords so people will come to your site, read the info then click on ads if they are in buying/researching mode.

However, I would recommend improving on the Xfactor/Clickbump methods. In my opinion, and experience, those methods are dying, if not dead in their original form. It's not enough just to get an exact-match domain name and a page of keyword-stuffed content. You need more, longer, better content and avoid those generic templates. And you will likely need to do quality backlinking too. Google's algo has changed and will be changing more, don't get slapped 3 months down the line after all your hard work.
