Lorenzo,
Here is a
guide that can help you understand more on your "How To" question.
You can also use the
Google Custom Search Engine so you have your own search engine that will display your Adsense ads instead of a parking solution.
You can go the arbitrage route or the organic search route, it all depnds what is in your capabilities.
The arbitrage route requires funds to get started, the organic search route requires SEO knowledge and for simple keywords you don't need to be a professional SEO'r to obtain some SERP's that drives the traffic to your pages.
And don't BUY stupid ebooks!
