I have the GoogleSniff and GoogleSpiderResults set up on my site if anyone wants to see what they do.
The GoogleSniff can be seen at
http://www.horseponyequine.com about half way down the page (between the Tagcloud and the google ads) and the GoogleSpiderResults can be seen at
http://www.horseponyequine.com/googlesniff .
At the time of writing this google had not crawled since installing these snippets so no details listed yet but should not take too long for some to show up.
I will leave these installed so people who want to use these snippets can see what they do.
