Your credit card is required upon a paid PPCnerd Plan signup to ensure that your PPCnerd Scripts can continue to run after the Free Trial finishes. Previously many of our PPCnerd users forgot to submit their card details before the Free Trial finished and that automatically stopped all their PPCnerd Scripts which resulted in many missed Google Ads optimizations. So we made the decision for users to submit their card details first and not charge the card until the Free Trial is finished. This means if you wish to continue using PPCnerd Scripts after the Free Trial is over, your Google Ads optimization automations can continue uninterrupted.
