I updated the URL patterns on one of my sites recently. There were 12k pages whose older URLs now 301 redirect to newer ones. There are no internal links to the old URLs. I noticed that so far (after ~2weeks) about 800 new URL have been indexed by G while Google is crawling the site like crazy. Is there science to this (re)-indexing process? Does G visit the same [new] page a certain number of times before it adds it to its index? Does it for a certain time period before doing so? The PR5 site in question has been treated favorably by G in its 1.5 years of existence sending ~3k visitors daily (the number dropped somewhat after the change).
I had the same problem, changing cms , google had to reindex my site , and now 20% of the google links are to the correct pages and 80 to not working pages :s:s
Wow I'm surprised your thread is still here. Everytime I ask a question about Google in relation to my site, the Mods immediately move my thread to some other forum. It's confounding.
Well, the thread is now within Digital Point Forums > Design & Development > Site & Server Administration instead of Google. It makes very little sense to me why it was moved
LOL. No kidding. I never understand why they move any of my threads. They were always about Google. Personally I think the mods are trying to fill up the light forums.
Btw, I've been observing the speed of new (rather permanently renamed) pages being indexed and it's going at a rate of ~40 pages/day. I only have about 5k pages to go
