As we all know that regular visitors don’t click on ads, around 90% folks who click on ads are coming from search engines.
Also for fact that Google pays more if your click-through rate (CTR) is higher, Google’s “smart pricing.” Being smart priced means that your click-through rate (CTR) is low and the money you earn per click is divided by between 2 and 10. For example, if a click would normally earn you $1.00, with smart pricing it could earn you as little as $0.10. Painful, isn’t it? Happily, this solution displays your AdSense ads to search engine visitors only, which means more clicks and a higher CTR.
For WordPress Users:
Note: Do take backup of your theme before you try this.
01. Go to Appearance => Editor.
02. Then choose functions.php file from right hand side and add below code:
$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,$source)!==false) return true;
}
return false;
}
03. Now, paste this code anywhere in your theme, where you want to display your adsense and they will appear only if the visitors are coming from search engines.
if (scratch99_fromasearchengine()) {
INSERT YOUR CODE HERE
}
}
04. Save the files and you are done.
For Blogger Users:
Note: Do take backup of your template before you try this. Only try this if you are familiar with blogger codes.
01. Go to Layout => Edit HTML, click on Expand Widget Templates and before </head> add Below code in to it:
//<![CDATA[
var ref = document.referrer;
var se = new Array('/search?', 'images.google.', 'web.info.com', 'search.', 'del.icio.us/search', 'soso.com', '/search/', '.yahoo.');
var sevisitor = false;
for (var i = 0; i <= se.length-1; i++) {
if (ref.indexOf(se[i])!== -1) {
var expiry = new Date ();
expiry.setTime(expiry.getTime() + 3600000);
document.cookie = "sevisitor=1; expires=" + expiry + "; path=/; domain=scratch99.com";
sevisitor = true;
}
}
//]]>
</script>
02. Now put below codes where you want your ads to be displayed:
if (sevisitor == true || results[2] == 1) {
<script type=’text/javascript’>
//<![CDATA[
var results = document.cookie.match ( '(^|;) ?sevisitor=([^;]*)(;|$)’ );
if (sevisitor == true || results[2] == 1) {
var adsenseString = "<div style=\"float: left;\">\n";
adsenseString += "<script type=\"text/javascript\"><!–\n";
adsenseString += "google_ad_client = \"pub-xxxxxxxxxxxxxxxx\";\n";
adsenseString += "google_ad_host = \"pub-xxxxxxxxxxxxxxxx\";\n";
adsenseString += "google_ad_slot = \"xxxxxxxxxx\";\n";
adsenseString += "google_ad_width = 336;\n";
adsenseString += "google_ad_height = 280;\n";
adsenseString += "//–>\n";
adsenseString += "<\/script>\n";
adsenseString += "<script type=\"text/javascript\"\n";
adsenseString += "src=\"http://pagead2.googlesyndication.com/pagead/show_ads.js\">\n";
adsenseString += "<\/script>\n";
adsenseString += "<\/div>\n";
document.write(adsenseString);
}
//]]>
</script>
03. Save Template. You are done.
