The latest Google Webmaster Central Blog post is titled “Better details about when Googlebot last visited a page”.

Vanessa Fox says, “Most people know that Googlebot downloads pages from web servers to crawl the web. Not as many people know that if Googlebot accesses a page and gets a 304 (Not-Modified) response to a 304 qualified request, Googlebot doesn’t download the contents of that page. This reduces the bandwidth consumed on your web server.

When you look at Google’s cache of a page (for instance, by using the If-Modified-Since or clicking the Cached link under a URL in the search results), you can see the date that Googlebot retrieved that page. Previously, the date we listed for the page’s cache was the date that we last successfully fetched the content of the page. This meant that even if we visited a page very recently, the cache date might be quite a bit older if the page hadn’t changed since the previous visit”. [cache: operator]
