I've received help in solving PHP problems in these forums in the past so I thought I'd give a little something back. Hopefully this is the correct forum to do so?
I wanted to receive an email when Google directs anyone to my site to tell me what keywords they have used to find my site.
A very basic and useful script, hopefully it can be of use to someone or maybe to expand on.
<?php
// Script to email you when Google refers traffic to your site.
$name=""; // add your name here
$email_address=""; // add your email address here
$keywords="";
$referrer=$_SERVER['HTTP_REFERER'];
if( (stristr($referrer, "google")) && (stristr($referrer, "search")) ) {
parse_str($referrer, $output);
$keywords=$output['q'];
$email_message="Hi $name, A visitor just arrived to your site after searching for '$keywords'. ($referrer)";
mail ("$email_address","Google referred a visitor","$email_message");
}
?>
