What Does Affiliate Link Mean?
An affiliate link is a specific URL that contains the affiliate's ID or username. In affiliate programs, advertisers use affiliate links to record the traffic that is sent to the advertiser's website. This action is all part of an affiliate program. Affiliate agreements commonly state that the affiliate is responsible for arranging its own affiliate link and making sure that it connects to the advertiser's website.
Techopedia Explains Affiliate Link
Affiliate marketing involves a company that recruits affiliates to sell its products or services online. When affiliates sign up at the provider's website, they are provided with a specific link to that website. When visitors to the affiliate's site click on the advertisements and go to the advertiser's site, the affiliate may receive a commission if that click leads to a sale. The advantage of affiliate links is that they track sales and offer opportunity to those who are interested (affiliates) in selling another party's products.
Sometimes affiliates are responsible for managing their own links.
