Today's question comes from Sanyog, who is building a site to help students prepare for an exam. If he would like to make $4000/month in Google advertising revenue, how much traffic will he need? In this episode, I share how I would start to build a business around test preparation, which is how I got started with passive income. I reference my friend Cornelius from PM Prepcast (management-prepcast.com/">https://www.project-management-prepcast.com/).
