To earn more you need to complete a daily checklist.
In order to complete the Daily Checklist you need to:
Click at least 2 PTC Adverts of any kind;
Click at least 20 ClixGrid squares. The more you click the more chances you have to win ClixGrid prizes which will then be counted towards the bonus as well (for example as a Premium member, if you earn the $10.00 prize you will earn an extra $1.20 with the Daily Checklist bonus at the end of the day);
Because not everyone has offers or tasks available to do, and to give everyone a chance, you are required to complete only one of the following:
Complete at least 10 CrowdFlower Tasks; *
Complete at least 2 offers from the offers page (except video offers); *
Complete at least 5 CrowdFlower Tasks and at least 1 offer from the offers page (except video offers); *
