Found in the Analytics tab, your earnings reflect your performance during the time period selected from the drop-down in the upper right-hand corner. It defaults to the past 30 days and is customizable. When you select different time frames, you'll see all your data reflect this time period as well.
Your balance (found on the left-hand side of your account, under the LinkIt tab) reflects what earnings are included in the current payment cycle. This amount will continually increase as you earn more and will rest to $0.00 when payment is on its way. Check your payment status here.
Please note: It may take between 24 to 48 hours for your full earnings from both orders and clicks to come through. At the top of your dashboard you will see a note on when your analytics numbers were last updated, please reference that to gauge when your earnings were last brought up to date.
