Let us start by borrowing a definition from Wikipedia; they explained affiliate networks simply as an intermediary platform between publishers (affiliate marketers) and merchant affiliate programs (advertisers). Advertisers use affiliate network as a means to advertise their product package so that publishers can easily access it, as they search for programs to promote
For both advertisers and publishers, both parties have to independently sign-up to the platform of the affiliate network. While publishers join most affiliate networks for free and pay a percentage of commission earned, merchants pay a premium to get their market on these networks.
Both Merchants and Publishers can enjoy a mutual relationship without fear of cyber fraud. This is made happen by the robust technology put in place by the affiliate marketing network.
ShareASale.com was acquired by Awin about 4 years ago, making them part of the largest affiliate network in the world. We have over 1600 employees in 15 countries. We were honored that out of all the affiliate networks in the world, founder Brian Littleton entrusted ShareASale to us.
There are actually closer to 6,000 programs on ShareASale, but with new ones being added daily, it's almost impossible to keep up. Luckily there's a great search functionality to help publishers find all the programs by keyword, niche or category, it's easy to find a program which fits your needs.
If I can assist anyone with ShareASale, please feel free to contact me. Thanks so much!
