I'm a newbie - and not terribly confident in the ways of Google. I've been reading your marvellous forum posts for a while now and have bookmarked lots of useful views and tools (thanks) but unfortunately haven't managed to self-diagnose my own 'complaint' - so here goes. I made keyword changes to 2 x PR3 sites on 1st October 2003 and a further minor image change 2 days ago to one of them. The one site is already showing 'new' cache (including the 2 day old new image) in Google - whereas the other is still showing 'old' cache. They've both got good keyword positions anyway - but I would welcome any plain language insight that's going around. What's the pecking order in Google with regard to refreshing their cache? Or am I being needlessly anxious?
