How long will old pages stay in Google's cache index. We have a new site that is two months old but we are seeing old pages even though we used 301 redirects.

Two months ago we launched a new website (same domain) and implemented 301 re-directs for all of the pages.  Two months later we are still seeing old pages in Google's cache index.  So how long should I tell the client this should take for them all to be removed in search?

Lately, Google has been taking a very long time to forget old pages - even when good 301 redirects are in place.  We have one site that we still see pages in the top 10... the destination page also displays in the top 10 above the old URL.

I don't know the answer to your question but can share my personal experience. I have waited as long as 10 months for old, redirected pages to be removed from Google's index.
