Question

When tracking links, do i need to put this code at the end?

return _gaLink(this,'#'); 

What exactly doe it do? My understanding of this is not clear.

Answer 1

Are you looking to tracking outgoing/external links? There is no Google Analytics function called _gaLink. Can you post up a snippet of your code?

_link() is used for X-Domain tracking, please see the documentation

If you simply wish to track “outbound links”, i.e. links to other sites, then use this piece of code (not this requires jQuery):

///////////////////
// _trackOutbound
jQuery(document).ready(function($) {
    $('a[href^="http"]:not([href*="//' + location.host + '"])').live('click', function(e) {
        _gaq.push(['_trackEvent', 'outbound', 'click', this.href.match(/\/\/([^\/]+)/)[1]]);        
        _gaq.push(['t2._trackEvent', 'outbound', 'click', this.href.match(/\/\/([^\/]+)/)[1]]);
    });
});
