GoFuckYourself.com - Adult Webmaster Forum - Is There Adwords Tracking For Mainstream Affiliates?

I found this article explaining the way to do it. In short you make the Sub Id contain just gclid. It appears to work for Amazon but will it work for Clickbank? Here is the article
AdWords Conversion Tracking for Affiliates

and here is an example of the code they are using. Let me know what you think.

<head> <title>Loading...</title> </head> <body> <?php $landingurl = 'http://www.merchants_website.com/mylandingpage.html?affID=12345&subid='; $gclid=$_GET['gclid']; $landingurl = $landingurl . $gclid; ?> <meta http-equiv="refresh" content="0; url=<?=$landingurl?>"> </body> </html>
