Our handy glossary should shed some light onto the main terms and terminology that affiliate marketers use everyday.
Affiliate: – An affiliate is an individual who drives traffic to online merchants. When a sale, lead, or other agreed action takes place, the affiliate will earn a commission. Affiliates drive traffic in many different ways but the most common methods are via website or blog content, or paid traffic from search engines’ advertising services. (See also: associate, publisher)
Affiliate Fraud: Fraudulent activity by an affiliate designed to generate illegal revenue. This can include using automated scripts to falsely create leads or clicks, or humans to do the same. Interestingly, some fraudulent affiliates set up dummy accounts with networks and generate large value cheque transactions for which payment never arrives. They are betting that the merchant may not reverse commissions generated in this way.
Affiliate Link: Is a special link containing code which tracks web visitors sent to a site by an affiliate. Each affiliate link contains a unique id specific to an individual affiliate and will record sales, visitors, and impressions generated and allow the merchant to attribute commissions.
Affiliate Network: An affiliate network provides a third party service to merchants and affiliates. The network will provide tracking, reporting and payment fulfilment services and allows merchants access to a large pool of affiliates. Networks generate performance based revenue by charging the merchant anoverride on top of affiliate commissions. (See also independent affiliate programmes).
Affiliate Programme: An affiliate program is a performance based form of marketing products or services offered by a website. The merchant pays a commission or lead rate on sales, enquiries or other actions to affiliate partners.

Cookie: A cookie is a small file placed on a user’s pc as they travel through the affiliate link (or any other link where the site wishes to track user activity). A cookie allows sales generated by affiliate traffic to be recorded out of session (i.e. if the web user subsequently returns to the site and does not use the affiliate link). Cookies are usually valid for a set period of time such as 60 days, during which time the affiliate will still earn commission on any purchases made by the customer they originally referred. Cookies can also be set by merchants to specify if commissions would be payable on a repeat basis within the cookie period (recurring commissions).
Cookieless Tracking: In response to growing concerns about increasing numbers of web consumers routinely deleting cookies from their PC’s and the impact of spyware programmes, some networks are beginning to introduce tracking solutions not reliant upon cookies. Webgains is one such network.

These files are used by many affiliates to create relevant commercial content for their own sites.
Drop Shipping: A lesser known form of affiliate marketing. This involves an affiliate taking orders and payment, and having arranged for a merchant to deliver product direct to client. No stock is required, and buying stock at wholesale prices means commission income is higher.
EPC: Earnings per hundred clicks. This is the most commonly used metric for determing the financial return provided by an affiliate programme. It refers to the average earnings of affiliates for every hundred clicks they deliver to merchant. Many affiliate networks make this data available to affiliates, but tends to be calculated in a slightly different way by each network.
