When you check out your referral's detailed earnings, you will see something like this.
Only earnings from PTC ads, Tasks and Offers are counted in the sign-up commission.
Earnings from Clicks by 5
Earnings from Taks by 20
Earnings from Offers by 20
Whatever is the total, is what your referral has earned (which qualifies towards the sign-up commissions).
Then add them up and see if it comes to $10. If it does then the referral has fulfilled the criteria.
*The above calculations are for Standard
members, multiply clicks by 2.5 & tasks and offers by 10.
Please note :
During the Christmas promo
, the referral commissions were doubled, so if your referral completed tasks and/or offers during the promo, the above calculations will not be able to determine how much he/she has earned.
