We have got a website that runs into 100,000's of pages (The site runs down to 4 folder levels ) and I was wondering how on earth I would go about building a site map for such a website.

There is no way that it would be possible to put just the links on one page, because of the size, so what is the best way to do it and provide maximium SEO for google at the same time ??

One way I was thinking was to just create a site map for each page. So for a single page the map for that page would just contain all the links from that page with the anchor text for those links.

Any thoughts on this ?? - How do huge sites like CNN etc produce a site map for goolge ??
