Making money online through Adsense and other ad networks

I've been very vocal about adsense A/B testing to see which ad type brings the best click through rate.  Apart from well know and standard adsense placements,  it is always a good practice to do A/B testing just to make sure you are getting the most out of your website.

Google's adsense blog  discussed one excellent way to do A/B testing.   Using a simple javascript.

<script type="text/javascript">
    var random_number = Math.random();
    if (random_number < .5){
        //your first ad unit code goes here
    } else {
        //your second ad unit code goes here
    }
</script>
<script type="text/javascript"     src="http://pagead2.googlesyndication.com/pagead/show_ads.js"></script>


You need to create 2 sets of adsense code with different custom channel.    Just dump the adsense code on the specified location above and you're good to go.
