Tracking Software, Preferably Free

I am looking for some tracking software, preferably free that will help me track conversions. A conversion for me is clicking a certain link on my landing page. The traffic will come from a number of different sources (all ppc) such as Adwords, Overture, Adbrite etc..... I would like it to track down to the keyword level.

So say the user searches for "Widget 3239" on Google and clicks on my ad. Once on my landing page the tracking software would track whether or not the user clicks on any link on the page.

Is there any software out there that will do this? Either that or a script that would track link clicks?

I.E

$keyword = $_GET['keyword'];
$url = http://www.affiliate.com;
<a href=http://www.mydomain.net/tracking/$keyword-$url>Click Here</a>

ummm good luck on getting this for free...

 

I didn't say it had to be free, just that it was preferred. I'm looking for any options right now.

 

Google Analytics is free and will allow you to track outgoing clicks, and works for all traffic sources not just Google.

You'll need to have your outgoing links call a client-side javascript function that uses the UrchinTracker() function to log a virtual event, rather that using a plain HTML Anchor link.

Paste this into the page header;

<script src="http://www.google-analytics.com/urchin.js" type="text/javascript"></script>
<script type="text/javascript">
	_uacct = "XX-XXXXXX-X";

	function jump_to(page_url, log_as) {
		urchinTracker('/outgoing_link_log/'+log_as+'.php');
		window.location = page_url;
	} 
</script>

Code (markup):

Then use the following format for outgoing links;

<A HREF="javascript:jump_to('http://www.google.com', 'Google')">Go To Google</A>

Code (markup):

I haven't actually tested the code, so the syntax is probably all wrong, but I'm sure you can see what I'm getting at.

Good luck,
