Google appliance

This is not code I have done but just a really handy bit of information for when using a Google search appliance on your site.

There are certain elements in a page that you want Google to look at when performing a search and some bits of information that are not that important.

When you want to exclude a section of the site navigation, breadcrumb etc then you can wrap the html in the following html comments

<!--googleoff: all--> Dear Google search appliance please don't include me in
 your search indexing, yours faithfully Web Developer <!--googleon: all-->
