Money site ideas

I'm learning a lot about PBN's and everything else that relates to it, but in the back of my head I'm always thinking about how people actually make money? My first guesses would be through affiliate and Ads, but what else? I can't come up with any decent ideas to make real money. If I figure out some strategy to rank my sites using PBN's I could create a marketing firm, but that seems farfetched as I dont imagine any reputable company would be to happy to learn that their digital presence if being ran by black hat methods.

I would love to know about any type of way you made money back in the day or are trying to at the moment or failed at. Obviously don't if It's sensetive information etc.

Yes you can make through marketing. but first you have to make strong profile on social medias, share your valuable ideas with audience after that you will able to make money.
