The AffiliateWP Sign-Up Bonus plugin incentivizes more affiliates to enroll in your program by providing a bonus at the time of registration. This plugin grants a bonus to new affiliates either upon successful registration or through manual addition by an admin, which is displayed in the “Unpaid Earnings” and “Referrals” sections of their affiliate dashboard. It also allows for manual adjustments and conditional approval settings to simplify the processes of recruiting and retaining affiliates.
