It’s free to join the SellHealth affiliate program, though you do have to apply and be accepted before you can start promoting their products. Once you’re accepted, you’ll have access to a number of tools, graphics, banners and more that you can use to promote SellHealth products. The sales are actually made at company-owned Websites, which look professional and handle all of the selling. Commissions vary, but the base rate is 30% of all sales and upsells, and SellHealth says you can earn up to $350 per sale.
There are lots of Amazon affiliates in this space, mostly because it’s a strong hobby (i.e. passion) niche with tons of products. Which is good, since tons of these big stores are very general in nature, making it possible for big outdoors sites to possibly even pick one or two stores to recommend (this, in turn, might have other advantages, too, like negotiating better rates with those brands).
Affiliate marketing is commonly confused with referral marketing, as both forms of marketing use third parties to drive sales to the retailer. The two forms of marketing are differentiated, however, in how they drive sales, where affiliate marketing relies purely on financial motivations, while referral marketing relies more on trust and personal relationships.
