Clicks
Represents the total times your referral link has been clicked. Each click is counted, regardless of whether the user completes the sign-up process. Multiple clicks from the same person are possible, so these are not unique.
Sign-ups
Indicates the number of individuals who have used your referral code and successfully completed the registration process. This number may be lower than clicks, as it includes users who may not have yet earned you any credit.
Earned
Shows the total credit you've earned from referrals. Credits are applied after the referred individuals make their first payment.
