making money from keywords

In my experience once you have about 500-1000 unique visitors per day to your site *at least* before you can start to make real money. You can make chimps change from day one from your 50 hits, but this article is targeted at those that have a larger audience, or perhaps are constructing a business plan (either real or in your head) and would like to know how to go about monetising your website. If you get more then 1000 unique visitors a day chances are you already make money from your site (if not you should be!) but my points are still relevant.
