Hi All,
This is my first post here after being directed from getting the DevWebPro newsletters going back a long time. I've been performing some SEO for free for a client as I learn the SEO ropes, I have been a site designer / programmer for a good many years. He had an existing site in Google with a low page rank for a year at the same URL, the new site was put up about a month ago and when searching Google this week finally the new site had been indexed and is crawled by Googlebot every 2 days or so and was coming up in searches optimized for the new keywords. However today it seems like the google cache has switched back to that of the old site and it is no longer coming up in the new searches. I'm not using any tactics that would cause us to be penalized, etc. Has anyone ever seen this happen before? Thanks for any advice, (Also I used googlecheck.com to verify I wasn't just hitting an old datacenter, it seems like all of them are using the old cache now).

Cheers,
Matt Rudderham
