I’m aware of people, circa 2010, building out huge sites where they started with affiliate offers and automatically generated thousands and thousands of landing pages and also had automated SEO spam to drive traffic. Some people made money that way but the affiliate plans that work are the sketchy ones (adult friend finder was probably the best at that time) whereas for normal products with Amazon or EBay you didn’t make a lot.
I think tools to make web shops quickly could be a good idea and probably not that hard but driving traffic is another thing. By 2011 the serious SEO spammers I knew had mostly switched to running paid ads, there was one guy who would charge $10,000 on his dad’s Amex to run ads, make it back in 3 days, pay the card and repeat. It is fine and good when it works but it is competitive. You need capital to start and could lose it if things went wrong.
I have not been involved in that sort of thing for a long time but I do know it is not easy.
