Split Testing LP's - Can you pass your adwords keyword

[mtrend]

Hi,

Ths is my first post here but have been lurking & learning for a while

My question is if I was sending my clicks from adwords to a splittest script like:

<?
if(rand(0,1) == 0) {
header("Location: http://www.example.com/split1sub=google-{keyword}");
} else {
header("Location: http://www.example.com/split2sub=google-{keyword}");
}
?>


To split test 2 landing pages, can I track the keyword through the whole journey to conversion ?

ie. Adwords click --> split-test.php --> Landing Page --> Offer / Conversion (eg. CJ, Azoogle etc)

If I can track which keyword converted how do I pass it from split-test.php through to the LP & ultimately Azoogle or CJ conversion to see what KW is converting?

Thanks in advance !
