They are dropping knowledge early on. That was the google backlink hustle. I swear I grew up too late. I was too young back then to know about any of that stuff, it wasn't until I was 17+ that I learned all the internet hustle people used to eat from back in the day from google, eBay, etc. Of course there's still ways to freak these systems today but it's much harder than back in the day. Facebook might have a new lea in their system regarding facebook ads, I haven't tried it out but based on a couple things I've read there might be something there.
