We just recently moved our website away from Yahoo Store to a customized ecommerce site, the domain is the same, however we have some old links that were ranked pretty good in google, what should I do with them? I'm currently doing 404 redirect to index page in IIS, but i'm afraid this will cause duplicate content issue. as no matter what link you type in after the domain, it's same as index page. Thanks!
You will not get benefit of old pages if you set 404 to redirect to homepage. To pass page rank you have to setup 301 redirection for your old links. Kailash
So i have to use something like Mod ReWrite to 301 redirect those old links one by one, what if i 301 those pages all to index page? Will it affect the ranks on my old pages?
I don't think it will help to redirect old pages to homepage. You will have to set respective URLs for 301 redirection. Also, your old links will lose their rank since they are now dead links. Kailash
