If you've ever wondered if someone is using your content on their own websites, now you can find out. Copyscape allows you to enter the URL of one of your pages and it will tell you if anyone is ripping it off.
It's a bit hit and miss. It returns results for your pages that may be under a different domain that you also own. It also seems to grab phrases that are common and could be used anywhere. Still, they may refine it in the future.
