AffiliateWP Sign Up Bonus is a WordPress plugin designed to enhance affiliate recruitment by offering a financial incentive upon registration. This plugin works in conjunction with AffiliateWP, allowing site owners to set a specific sign up bonus that affiliates can earn when they register through the AffiliateWP registration form or are manually added by an admin. The bonus is displayed as a referral labeled 'Sign Up Bonus' in the affiliate's dashboard, contributing to their overall earnings and visibility in the system.

The plugin also includes features such as the option to require approval before bonuses are awarded, ensuring that only verified affiliates receive their incentives. Additionally, administrators can customize bonuses on a per-affiliate basis, providing flexibility in managing affiliate rewards. This system not only motivates new affiliates to join but also aids in creating a structured approach to affiliate management, thus potentially increasing sales and engagement.
