There are two reasons why XHTML has a problem with Google's AdSense code:
- It uses the javascript function Document.Write(), which XHTML can't handle because it would output new markup whilst the document is still being parsed.
- It creates an <iframe> element, which cannot be used with strict varieties of XHTML.
It's inconvenient, but fortunately not impossible to deal with. The solution is basically to render the ads as plain old text/html inside an object element. This does mean that you need to put your AdSense code into a separate file, referenced by the object element. An example using PHP...
Given the original AdSense script code:
<script type="text/javascript"><!--
google_ad_client = "pub-8595518574874016";
/* Homepage, vertical, wide */
google_ad_slot = "5511616855";
google_ad_width = 160;
google_ad_height = 600;
//-->
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>
We replace that with:
<object width="160" height="600" data="/includes/adsense.php" type="text/html">
</object>
And create the file /includes/adsense.php as:
<?php header("Content-Type: text/html;charset=utf-8"); ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html lang="en">
<head>
<title>Sponsorship</title>
<style type="text/css">
body {margin: 0; padding:0;}
</style>
</head>
<body>
<script type="text/javascript">
google_ad_client = "pub-8595518574874016";
google_ad_slot = "5511616855";
google_ad_width = 160;
google_ad_height = 600;
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js"></script>
</body>
</html>
Obviously, you have to substitute your own google_ad variables. I found this solution as an example somewhere, but I lost the link, so apologies for neglecting to give credit.
