By helping your co-workers set up their own sites and instructing them about affiliate programs, you will be establishing more awareness and support for your program. Organize the company behind your program. The results for your affiliate program will be very tangible, so show that qualitative and quantitative information with everybody. Don't be shy about tooting your own horn, since nobody else is going to do it for you. When you get positive feedback about the program, share it with everyone.
Nothing succeeds like excess.
It's impossible for you to find every site that may become your next great affiliate. So ask around the office for co-workers to refer potential affiliates to you. Their job is also to work with dot-coms in your industry, so they likely know some gems that you have not come across. You will find that internal support is imperative to the success of your affiliate program. Not only will it make your life and job more pleasant, but it will also assist you in perfecting your program.
