The invention provides a system and method for generating affiliate links that may be shared between users of computing devices. A method of the invention may include the steps of receiving from a server system a user identifier of a client system (e.g. smartphone with client application) and persistently storing the client identifier at the client system. Information identifying an item such as a product or retailer may be displayed as well as an indication of a single action to be performed (e.g. “share” button) to generate an affiliate link from the product information. In response to the indicated single action being performed, the client system automatically sends relevant item information and user information to the server system which creates an affiliate link by referring to a database of affiliate information. The generated affiliate link is communicated to the client system which may communicate the affiliate link to other computing users directly via SMS or via other computing applications such as email or a social network. The user initiated the sharing action may earn revenue when other users purchase an item by interacting with the shared affiliate link.
