I, like LaRue, will only endorse products I use and trust. So it’s very important to appeal to the fitness professional as well as the public, especially with your website since that is the easiest way to reach so many people in today’s world. It’s also important to foster a healthy relationship with some form of communication. An e-mail blast or newsletter here and there helps keep us up-to-date on your products and promotions.
There are a lot of ways to do it, as far as marketing and linking the affiliate. Personally I would prefer a website banner to start. And if you would provide inexpensive marketing materials, I would be far more likely to market a product offline. I’m not going to invest my own money marketing your product when I only earn 5-15% on total purchases. With that being said, a discount for verified professionals would help get your product in our hands.
Essentially you need to make it as easy and simple as possible for us. Get it in our hands any way you can, and really sell the product to us. Make us want to sell your product, and wish all our clients had one.
