[...]PHP:Catching keyword from search engine ?? Istanto Blogs[...]…

Too much regex calls. They are heavy functions retarding execution time. if i am the last of 50 search engines, it will have to execute 50 eregi before finding me. Remember that this script is called on almost every pages. In fact, it s called on the most importants pages, the ones we want to target. So we want it fast. Try this code, it makes the same :

$url = parse_url($_SERVER['HTTP_REFERER']);
$possibles_params = array(‘q’,'qt’,'p’);//&q= &qt= &p= …
parse_str($url['query'], $params);
foreach($possibles_params as $val)
{
if($params[$val]) echo “referer : “.$url['host'].”keywords : “.$params[$val];
}

Note that it keeps the complete referer name server. Because it can be useful in SEO to know if it is refering from http://www.google.com, http://www.google.fr, http://www.google.co.uk, etc …

Good luck !

get_keys(); if (count($keys)) { echo “You’re directed to this page from $keys[2] search engine, within Keywords ‘$keys[1]‘
“; } ?>

(it is a .shtml and I set the httpd.conf to AddType application/x-httpd-php .shtml)

// Microsoft Bing
preg_match ( “/{$this->sep}q=(.*?)\&/si”, $this->referer, $matches );
$this->keys = urldecode ( $matches[1] );
$this->search_engine = “Bing”;
