Does anybody have any thoughts on this? It seems like a great way for google to spider only pages it needs to. Has anybody actually implemented this with their site?

Hi Anacrusis

I have heard about this too. Indeed I am preparing a sitemap at the moment to submit. One chap I met said he had submitted to google sitemap and saw amazing results in under a week. Got to be worth a try.

maybe this will help u to make up your mind

great post praaven ... thnks

I've used it, and it seems to work. After I put one in I got all the pages on my sitemap indexed after about a week. I think the purpose is more for sites where you can't get to all the pages through direct links, because the google bot should follow your links and index most of the pages it can get to even if you don't have a sitemap in place.
