I've also never heard of bidclix, but have been using Adsense on my (tech) site for a while now and paid off all hosting fees I've ever paid!
As opposed to other "affiliate" programs this one pays for each clicks, no need to buy from the "clicked" site before you get a commission.
Also the amount per click depends on your page content and what the keyword that triggered the ad was worth. See their
AdWord program for details.
You also need a high traffic site to get a good revenue.
All I have to say is if it wasn't for this program, my site may not have been around anymore!
