Google Adsense - who uses them to make money...

From what I'm gathering is you can research on the highest paying keywords for that day/week - create a web page with articles pertaining to the highest paying keyword for that period, google's adwords will display ads according to your content on the site. So say I make a site about "mesothelioma information" according to http://www.adsensepay.com/ the CPC for that is $30.98 - so you're telling me I will make approx 30 bucks a click? I know targeted ads and all the other mumbo jumbo I can make anywhere from $1-3 per click. How long do these "high paying keywords" stay #1 on the charts.. So just a small strategy pay attention to the high keywords daily and make sites relevant to that information and get traffic to your site and wish for clicks!


Have any of you actually made decent money from Google Adsense?
