Tracking First Cookie vs Last CookieDawn Rossi, 05-03-2008 |
When tracking affiliate IDs or SIDs, there are two popular methodologies you can choose from:
1. First Cookie
The first affiliate to refer traffic to your website earns credit for the sale.
Example:
Andrew refers Robert
Jim refers Robert
Robert buys
- Andrew earns the credit
2. Last Cookie
The last affiliate to refer traffic to your website earns credit for the sale.
Example:
Andrew refers Robert
Jim refers Robert
Robert buys
- Jim earns the credit

Choosing which methodology you would like to go with is strictly a business decision. Once you've made your selection, be sure to communicate this to your affiliates and motivate them accordingly.
Below are the two different scripts to implement first cookie vs last cookie tracking:
Track affiliate referrals by First cookie:
// If we have an affiliate ID cookie, use it
if (!empty($_COOKIE['aff_id'])) $aff_id = $_COOKIE['aff_id'];
else
// (No cookie)
// If we have an affiliate ID in the URL, use it
if (!empty($_GET['aff_id']))
{
$aff_id = $_GET['aff_id'];
// Save affiliate ID cookie for 90 days
@session_register("aff_id");
@setcookie("aff_id",$aff_id,time()+3600*24*90,"/",".YOURDOMAIN.COM");
}
Track affiliate referrals by Last cookie:
// If we have an affiliate ID in the URL, use it
if (!empty($_GET['aff_id']))
{
$aff_id = $_GET['aff_id'];
// Save affiliate ID cookie for 90 days
@session_register("aff_id");
@setcookie("aff_id",$aff_id,time()+3600*24*90,"/",".YOURDOMAIN.COM");
}
// If we have an affiliate ID cookie, use it
else
if (!empty($_COOKIE['aff_id'])) $aff_id = $_COOKIE['aff_id'];
1. First Cookie
The first affiliate to refer traffic to your website earns credit for the sale.
Example:

session_register() is no longer valid
so you must replace
@session_register("aff_id");
with :
$_SESSION['aff_id'] = $aff_id; only if u use sessions and you already start the session ( session_start();)

@session_register("aff_id");
