I need to add this, because I don't think I made myself clear the first time out.

Every time you do a search, the search engine goes out and re-loads all of those pages and turns them into the pretty images you see. They don't load from their cache, the actually connect to your server and pull the page again, for each and every search. Those pages are not really viewable, the ads are not clickable, and if the user clicks to see the page, the page will be reloaded again.

So if you are popular on a search like "porn", you could end up serving thousands of phantom pages per day, with no actual users. So where you may see stats that show plenty of traffic from this site, the reality is that the traffic may be nothing more than their bot pulling your page again to show it to a single user.
