Google Adsense and YPN (Yahoo Publisher Network) Ads Rotated by Country
I have never liked using IP addresses to sort ads mainly because of the wasted space (Not to mention the Countless people using Proxy's) So I created a simple script to rotate my ads Based on Language and Country.By now anyone using YPN (Yahoo Publisher Network) knows they only pay for US Traffic - and you can lose a good bit of income by using their ads alone.
So you could include in your Header , Footer , or Body the files named for the size and type ads you want shown :
Code :
<?php
include("728x90.php");
?>
For this Example - I've created a file named 728x90.php
Code for 728x90.php :
<?php
$locales = $_SERVER["HTTP_ACCEPT_LANGUAGE"];
if ( $locales == "" ) {
include("google-728x90.php");
} else {
$semicolon = array(";");
$lesssemicolon = str_replace($semicolon, ",", "$locales");
$breakdown = explode(",",$lesssemicolon);
$lang_count = strtolower("$breakdown");
}
if ( $lang_count == "en-us" ) {
include("ypn-728x90.php");
} else {
include("google-728x90.php");
}
?>
The reason for the "$lesssemicolon" is due to the fact Locales may be separated by either semi-colons or commas.
Of Course you would have to create mini php pages named "ypn-728x90.php and google-728x90.php" which simply contain your ad code(s) - Depending on size and type of ad programs you use.
The only problems I've seen so far with this method - Is that a lot of FireFox / Opera users have never set their location on their browser , But it doesn't bother me too much seeing the Script will still show Google ads to anyone not in the US or with no locale set.
This might actually be a good thing seeing you'll still be giving Google some US traffic as well - Thus not making them upset at you for sending them only non-US or Foreign Web Traffic.
Hope it Helps
