Is there a wordpress popup plugin which triggers based on referrer

$popup = "<your popup code goes here>";

//First we check if we can get the referer
if (isset($_SERVER['HTTP_REFERER']))
{
	//next we get the hostname part of the ref url
	$ref = parse_url($_SERVER['HTTP_REFERER']);
	$refhost = $ref['host'];
	
	//now check if the refhost contains 'google'
	if(strpos($refhost,"google") !== false) {
		// its found echo the popup code
		echo $popup;
	}
}
