The trick to using this feature effectively is to find an alternate site that pays a high click rate. There are several affiliate sites that have these codes set up and I have tried a few of them. There were a couple where the payouts were not worth my time but there are other that are paying up to $12 to $15 per click. After just a few days of using the alternate feature you will see an increase in the number of impressions and you won't have any lost clicks. Once I started using the alternate url I saw a sharp increase in the number of clicks I was getting. I also started keeping track on which ads had the highest click through rates and the higher payouts. I narrowed these down to just a few that I use now, but there is one that still gets a great response. The best part about setting these up are they are usually 100% free to join.

Here are a few steps to get started:

   1. Locate websites that offer this functionality, the one I use most frequently is http://www.modernclick.com
   2. Once you sign up with these programs some are instant and others may take a couple of hours for approval.
   3. Sign into your Google Adsense account.
   4. Once in Adsense Setup go to Alternate ads or colors and select 'Show ads from another URL'.
   5. Type in the url you got from your affiliate site, for example - http://moderncl1ck.com/eb/3/xxxx/0 - where the 'xxxx' is type in your own code.
   6. Generate your Adsense code.
   7. Paste your Adsense code on your webpage.

That is all you need to do to start maximizing your Adsense earnings. It is very easy and only takes a few minutes to get it set up, and the long term benefits from using the Alterante URL option are huge.  Kevin resides
