Here is how to do it, you’ll still need a server and a domain. Point all your traffic towards a php file i.e. http://www.mydomain.com/trackandforward.php
Then place all your retargeting pixels in to the trackandforward.php file and put a meta refresh at the the end. The page will load the retargeting cookies will be placed and then the user will be sent on his way to the affiliate offer without even knowing it.
<?php
$searchlink = ‘http://www.affiliatenetwork.com/offer.php?affid=123’;
echo “<html><head><title>Loading…</title></head><body>
<img src=\”http://www.adroll.com/orwhoeveryouuse.php?r=123\” />
<meta http-equiv=\”refresh\” content=\”0;url=”.urlencode($searchlink).”\”>
</body>
</html>”;
?>
This works especially well with display advertising using banners that pre-qualify your audience. Or use it post landing page between a ppv lander and the affiliate offer.
