What many webmasters do not realize, however, is that you can easily replace those unpaid ads and earn bonus revenue from your website. All you need to do is make a simple change to your ad codes.

In the case of Google's AdSense program, this is done by adding an alternate URL to your code. It is a very simple process that will typically take you less than five minutes. Using the AdSense online wizard, you simply add an alternate ad URL to your code, then copy and paste the new code into your pages.

You can view a sample of an AdSense alternate URL integration at:

Once you have made the change to your ad codes, you will show an alternate ad of your choice in place of the PSA ad that would normally have appeared. Alternatively, you may also select to show a simple background color in place of your PSA ads, but be aware that won't earn you a dime and it can look strange to display a blank space on your pages, whatever the color.

So you've decided to add an alternate URL to replace those unpaid ads. That's smart. It's actually amazing that so many AdSense users do not take advantage of this process. Google makes it very easy to do, but for whatever reason, most webmasters simply ignore this option and forego additional profits from their hard-earned traffic.
