Refer-a-friend contests allow entrants to increase their chances of winning when they share your campaign. Entrants are awarded bonus points when they share their unique referral URL and someone clicks it and submits an entry of their own.
After each refer-a-friend contest entry, ShortStack provides the participant with a unique referral URL via an autoresponder, in-app popup or both (it’s up to you). ShortStack automatically awards entrants with bonus points if someone clicks the entrant’s URL and submits an entry. You choose the number of points each referral is worth and cap the maximum number of bonus points entrants can earn.
Social media sites like Facebook don’t allow you to require participants to share content in order to enter (Facebook has shut down campaigns right in the middle of a contest for implying that sharing alone would serve as an entry mechanism). Refer-a-friend contests give you the opportunity to incentivize sharing without breaking site guidelines or best practices.
For an entrant to receive bonus points, the people they refer must also enter their information via your form. This gives you the opportunity to build your email list and collect valuable marketing information.
