Hi! I have changed my site's script 1 week ago. Normally, All URLs has changed to. So i want to delete old approximately 5000 URLs from Google. How can I do?
just go to google/addurl..... and then choose delete site, just like you do before when you add website to google
Sometimes it can be useful to perform a 301 redirect on old indexed URLs to your home page or a more appropriate page. I think eventually google figures this out and deletes the old URLs, and in the meantime you benefit from any old page rank. That said, 5000 is a lot, so you would probably want to redirect a root site if possible rather than each individually.
