I just deleted about 800 sites from my server and due to a reorganisation. I have a error404.html which appears everytime a user tries to access a deleted file. It basically says that the site has moved and offers some links to the main sections index pages of my site. So far so good. But: What will Googlebot see when spidering the deleted sites. She will see 800 sites with exactly the same content (This site has moved click here). Will she regard it as dup content? What is the best way to get these deleted sites out of google?
