Traditional affiliate networks enable merchants to offer publishers a share of any revenue that is generated by the merchant from visitors to the publisher's site, or a fee for each visitor on the publisher's site that completes a specific action (making a purchase, registering for a newsletter, etc.). The majority of merchant programs have a revenue share model, as opposed to a fee-per-action model.[2]
For merchants, affiliate network services and benefits may include tracking technology, reporting tools, payment processing, and access to a large base of publishers. For affiliates, services and benefits can include simplifying the process of registering for one or more merchant affiliate programs, reporting tools, access to product API's and payment aggregation.
Affiliates are generally able to join affiliate networks for free, whereas there is generally a fee for merchants to participate. Traditional affiliate networks might charge an initial setup fee and/or a recurring membership fee. It is also common for affiliate networks to charge merchants a percentage of the commissions paid to affiliates, this is known as an 'over-ride' and is payable on top of the affiliates commission.
Affiliate networks are also wary of new affiliates who do not have any known connections or experience in the industry because there have been many instances where individuals have tried to game the affiliate network. The current technological advances have given many tools to affiliate networks to fight cyber fraud in a more meaningful and effective way.
Affiliate Marketers can also join as an affiliate directly with major companies as they may have affiliate programs on their websites.
