Here's an interesting question. I've started a new website that for now I'm relying heavily on search engine traffic, and I'm wondering if anyone knows of a PHP script that can grab the search term which got the user to the site. I know of the obvious $HTTP_REFERER script which tells what site a user supposedly came from (although it's unreliable), however does anyone have a script for logging what search phrase was actually used on Google, MSN, Yahoo, etc. to find the site?
