hers a nice search for outgoing links from a site: LinkFromDomain:URL Search for: LinkFromDomain:your domain .com Thats a good way to find out, if you are linking to a site you dont like. Or you can find out which sites are linked from your competitor. I hope this can help If you hafe a blog it can help to find spam linke "v i a g r a" links in you site.
You can also use the advanced search in combination with LinkFromDomain to look for links pointing at domains within a specific geograph region. This new linkfromdomain could be very helpful to get rid of spam link on blogs and even forums. I like it
