Back in August 2008, I wrote a post on how to optimize form length with input analysis with Google Analytics. This is still a very relevant topic, as forms are still essential to collecting data from visitors.  I still cringe when I see a form that has a ton of fields, and I know many of you do as well.  This post will show you how to take action to shorten your forms and remove unneeded fields, which usually results in higher conversion rates for your forms.

The old post referenced the traditional/syncronous version of the Google Analytics tracking code. This new post features the newest release by Google, which is the asynchronous code execution.

Please note that I am not going to re-do the entire post, just the code portion.

So here is the code update:

Traditional Snippet (Synchronous):

function validate()
{
isEntered(document.getElementById('name'),'name');
isEntered(document.getElementById('email'),'email');
isEntered(document.getElementById('phone'),'phone');
isEntered(document.getElementById('company'),'company');
isEntered(document.getElementById('comments'),'comments');

frm.action='/thankyou.aspx?src=contact_us.htm';
} 

function isEntered(el, field_name)
{
     if((el.value=="") || (el.value==null))
     {
     pageTracker._trackPageview('/contact_us.htm/empty/'+field_name);
     }

     else
     {
     return false;
     }
}

Asynchronous Snippet (NEW):

function validate()
{
isEntered(document.getElementById('name'),'name');
isEntered(document.getElementById('email'),'email');
isEntered(document.getElementById('phone'),'phone');
isEntered(document.getElementById('company'),'company');
isEntered(document.getElementById('comments'),'comments');

frm.action='/thankyou.aspx?src=contact_us.htm';
} 

function isEntered(el, field_name)
{
     if((el.value=="") || (el.value==null))
     {
	 _gaq.push(['_trackPageview', '/contact_us.htm/empty/'+field_name]);
     }

     else
     {
     return false;
     }
}
