Here is what Wikipedia says about Googlebot: It is the search bot software used by Google, which collects documents from the web to build a searchable index for the Google search engine.
You can quickly and easly view your website as Googlebot by viewing a web page in Google’s cache. SEOpen is a Fiefox tool which make this a snap. Once you install the plugin right click on a web page then scroll down to SEOpen/Google/Google Cache. Below is a screen shot of what happens next. Once you click on the “text only version” you will see what Googlebot sees.
Alternatively, you can use a Googlebot simulator application such as this one. Now you can view your website through the eyes of Google.
