301 Redirects to Move 60,000 URLs Changing a large site's linking structure ok? kfarmer
Our website has something like 60,000 URLs that all show up well in Google, but a coming upgrade will force all of these URL's to be of a different form.
We've been planning on sending a 301 permanent redirect to all requests for these old URL's to go to the new URL's. I've read some good posts about Google and using 301 redirects like:
...] webmasterworld.com [ ...] webmasterworld.com
and this seems to be a fine practice. However, has anyone had experience changing so many URLs? Does anyone know how long Google's SERPs will bounce around before the new pages get served up instead of the old ones? Any idea how much risk that for some period of time neither URL gets served up?
