How to remove my old pages from Google without 301?

Hello

I have changed my website from ASP to ASPX. Now I think that google has made my new pages Supplemental because the content of my old and new pages are same.

I have read about 301 redirect but at this stage is is impossible to apply this on my old pages because of the severe complexity of my website.

Is there any other way to exclude my previous pages form google index ? What do you people suggest ?


Thanks.

I think everything is possible . So even if you have to work very hard with the 301 redirect, do it.

For exclusion from google use robots.txt disallow, but take into account that the link and PR value will not move to the new ones. This way you can loose much.

So, I suggest 301.

its ok SE's will know if that page is not existed, and your new page stilll get crawled. 301 still best on this matter as always. a good option.

Your question is a bit confusing. Why dont you just remove old pages from your site. if no links going to them what difference will it make. Why do you want to keep to lots of the same content on different pages on your site?

Or change conetent. There is little long term advantage having multiple copies of two identical pages on your site.

Not criticising just wondering..

Gazzahk is right (sorry can't give you RP's gazz... you have them all right now)!

If you have kept the old pages there and added duplicate new ones you will have problems... you should add 301 redirects.
If you have kept the same urls but altered the file extensions you could add a single redirect match command to forward ALL traffic to the corresponding new pages; if you have changed the filenames you will have to do it "the long way"

At the very least you should redirect your high-level pages and you really need to delete the old (duplicate) pages asap.

RObots text to disallow
sitemap to show where
301's to help them along the way

otherwise, if they don't want to listen, just let em be.
