Refresh a Google Adsense banner with Javascript

Often bloggers and site owners use galleries to have a greater number of pages, adding pages means adding clicks. Each photo is a click, is a pageview. When you click next and the whole page is refreshed, with new photo, new link and… new banner impression. This is the goal: increase banner impressions.
Show more banner, have more pageviews, more time spent on your site and reduce bounce rate statistics (which bring better power when you sell banner).
From a user point of view I don’t like when this happens, but as a developer and as a owner of sites I understand the problem.
Google Adsense and other Ad-servers codes are written in javascript, so it’s not easy to refresh them with javascript and sometimes theri policies don’t want too.
A solution that worked for me is embedding their code in a local iframes and then refreshing that iframe with javascript.

Watch a demo here: demo refresh banner google adsense with javascript

Here is the html:

<a href="javascript:;" id='gobut'>refresh banner google</a>

<iframe src="refresh-banner-iframe.php" width="300" height="250"/>

The iframe file refresh-banner-iframe.php contains only the script from Google Adsense (or from your ad server). When you click on the refresh button… here is the jQuery function attached to the click event:

$(document).ready(function() {
	$('#gobut').click(function() {
		$url = $('iframe').attr("src");
		$('iframe').attr("src","about:blank");
		$('iframe').attr("src",$url);
	});
} );

There are different ways to refresh the content of an iframe. If the source on the iframe is in the same server as the container you can also use something like this:

document.getElementById(YourFrameID).contentDocument.location.reload(true);

But if the iframe points to a src on a different domain, you will receive a denied access error to the iframe’s contentDocument property by the same-origin policy.
So I’ve decided to work from the parent window, changing the url of the iframe and rewriting the same url.

You can use this trick to the next-previous commands of your gallery to refresh banners and stop realoding all the pages. Your time spent statistics will be better, your banner impression will increase, you site pageviews will be the same, but users will be happier.
