I've taken over the managment of a site, which has about 10 domain names, all of which point to exactly the same content. I don't think this is doing anybody any good what so ever. So I'm think of moving the 9 extra domains to another IP address, then having a redirect to the correct site. What is the most SEO friendly way of doing this? so that xxx.com/fredy/bert/jane maps correctly to yyy.com/fredy/bert/jane I'm thinking the redirects should be permanent so that the likes of big g, etc. know to stop bothering with the old domains, but they still work if someone has one bookmarked.
