The following function pulls the ranking
from the cd parameter in Google and pushes it
to a custom variable in Google Analytics
called "Rankings."

For information on the applications of this
see John Doherty's post on SEOmoz:
http://www.seomoz.org/blog/gettings-rankings-into-ga-using-custom-variables

Updated 3/11/2012 to change the scope in GA, check for any
Google property (not just google.com) and return ranking
for dynamic messaging applications.

function rankingsPush()
{
  var url = String(document.referrer);

// confirm they came from G

var urlVars = {};
var parts = url.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value)
{
urlVars[key] = value;
});

// Push to GA Custom Variables
_gaq.push(['_setCustomVar', '1', 'Rankings', urlVars["cd"], 2]);

// Return the ranking in case
// you dynamic targeting based on ranking

return urlVars["cd"];
