Example of such delayed click tracking code could be (with bold is marked change):
<script id="pap_x2s6df8d" src="https://localhost/PostAffiliatePro/trunk/server/scripts/clickjs.php" type="text/javascript"> </script> <script type="text/javascript"> <!-- setTimeout("papTrack()",30000); //--> </script>In this case we just added setTimeout javascript function, which delays execution of function papTrack for 30 seconds.
If user will leave page sooner, click will not be tracked !
In this way you can give commissions to your affiliate only if user, which clicked on your link will read the page at least 30 seconds.
I hope this easy trick will help you to filter some fraud clicks :-)
