The Mention Me referral journey is powered by two key tags: the **Referrer tag** and the **Referee tag**. These tags promote referrals at optimal touchpoints and capture the information needed to issue rewards. ## Referrer tag on the post-purchase page This tag performs two essential roles. It promotes referral to customers on the post-purchase page (the most effective touchpoint) and collects order details so rewards can be issued as applicable. Referrer tag on the post-purchase page ## Referee tag in the checkout This tag inserts a link (or form) that says: **"Been referred by a friend?"**. Customers who click this link will be asked to identify their referrer to receive their reward. You can control where the link appears, what it says and how it looks in the platform. Place the referee tag in your checkout, typically close to any promo code or voucher code box, to support name referral.
