How have I not heard of this before? Google has a registry hack (for IE only, sadly), that allows you to see what ads Google would put on a site if AdSense were to be put on it – even if it currently has no ads. Very cool. If used on a site that does have AdSense, you can use it to get the links from the ads so you can visit the URLs without clicking on your own ads.
