Web hosting is just one affiliate market you could try out and make some good and continuous income. Just remember that to be successful on your endeavor also means that time, effort and patience is needed. The best Web Host affiliate program that I've come across is at www.HostGator.com. I use their hosting for quite a few sites. The service is great and the price very reasonable (only $9.99 per month for unlimited domains), and the affiliate reward it nice too.
Nobody has invented the perfect affiliate market yet. But some people do know how to make it big in this kind of market. It is just knowing your kind of market and making the earnings there.
Until Next Time...
