I am currently studying PPC and want to run a campaign while learning PPC. I feel that I will learn the material quicker if I apply PPC theories while watching tutorials. I understand terms such as impressions, clicks, bids, cost per click and conversion percentage. My understanding is that I need to pay $40 to open a professional amazon account before I can practice PPC. Is it mandatory to open a $40 professional amazon account before being able to access the Amazon Sponsored Products page?
