I would like to know what's the best way to track keywords your visitors entered before clicking on your AdWords ads?
I thought that I could get this with PHP through $_SERVER['HTTP_REFERER'] but this var is empty when a visitor gets to my landing page by clicking on an ad.
When then they get to my landing page through a search result, I do get the keywords they searched for though.
Thank you for your help.
