This site might seem authoritative, but it doesn’t really cater to the visitor. As you can see the site contains a ton of ads, and doesn’t do much to provide a good reading experience. The content is long, but it’s also very hard to read. You could easily create a site that reviews this product and provides a better reading experience and higher-quality review.
You should also make sure you aren't competing with your own affiliates for eyeballs. Any marketing channels you're using, such as search engines, content sites or e-mail lists, should be off limits to your affiliates. Put marketing restrictions into your affiliate agreement and notify partners immediately. It's your program--you set the rules. Or, if you prefer, you can let your affiliates run the majority of your internet marketing.
