So restricting your ad to display only to the visitors that come from search engine can help you increase the CTR of your ad.
To display ads only to search engine visitors, add the following code to your functions.php file.
$ref = $_SERVER['HTTP_REFERER'];
$SE = array('/search?', 'images.google.', 'web.info.com', 'search.', 'del.icio.us/search', 'soso.com', '/search/', '.yahoo.');
foreach ($SE as $source) {
if (strpos($ref,$source)!==false) {
setcookie("sevisitor", 1, time()+3600, "/", ".yourdomain.com");
$sevisitor=true;
}
}
function visits_from_searchengine(){
global $sevisitor;
if ($sevisitor==true || $_COOKIE["sevisitor"]==1) {
return true;
}
return false;
}
Make sure you change yourdomain.com to your domain. Then, add the following code snippet to single.php file.
<?php if (function_exists('visits_from_searchengine')) {
if (visits_from_searchengine()) { ?>
YOUR CODE HERE
<?php } } ?>
Don’t forget to add your AdSense code by replacing YOUR CODE HERE.
