Users adding their personal affiliate link (e.g. for Amazon.com’s affiliate program which redirects to a relevant product) to a popular post generate a lot of clicks and thus receive a share of the revenue. Due to its engaged user audience and scale, users interested in earning an income by posting affiliate links are attracted to the Pinterest platform.
