I have a critical site I am having a hard time getting Google to cache. We recently made minor improvements to the site and dear Google is still sitting with the old version, which is really frustrating our SEO efforts.

We added some good quality, relevant links to the existing ones in the hope that Google would visit the site sooner but no go. We submitted to Google twice (which I don't usually bother to do with an existing site in Google's index) and still no go. I've run a check for anything that may be causing a problem and find nothing. Server header info:

HTTP/1.1 200 OK
Server: Microsoft-IIS/5.0
Date: Tue, 20 Nov 2007 08:11:40 GMT
X-Powered-By: ASP.NET
X-AspNet-Version: 2.0.50727
Cache-Control: private
Content-Type: text/html; charset=utf-8
Content-Length: 22318

I'm stumped! Could it have anything to do with the fact that we moved the hosting of the site from one server to another? It seems like all is in order there with DNS records pointing to the right places, etc...what else? Anyone have any ideas?

Do your server logs show any googlebot visits since the changes?

Thanks John, problem sorted out. For anyone having a similar problem in future: create a sitemap and submit to Google Webmaster Central. Site was cached the same day I did this. Should have thought of it before!
