Googlebot

The Googlebot is a software that is spidering the web all the time. If there are more incoming links to your site, there is a greater chance that it arrives at your site through an incoming link. Since PR ranking is related to number of incoming links, that means more visits for higher PR sites. The frequency of Googlebot's visit will also depend on the frequency of which your site pages are updated. Every time Googlebot visits, it will know whether your page had changed or not. If it doesn't change too often, there is no reason it need to come that often. The ideal efficiency that the programmers of the Googlebot want to achieve it to have the visit frequency match the page update frequency. Hence, a blog that is updated daily will be visited more often than a site whose pages does not change.

To see when was the last time that GoogleBot has visited your site, you can type in your domain name (such as "yourdomain.com") into the Google search field. Google will bring up information o your site. One of the links there will be "Show Google's cache". Click on that link and Google will show you the cache version of your page as well as when that page was cached.

2. Or you can look at your server log for the user-agent named "Googlebot". See here.

The time listed on (1) and (2) may be different because a Googlebot may visit but not necessarily cache.
