So, pretty much anyway you slice it, you often need your own website. I think even the common tactic with Instagram marketing, which often uses OGAds typically requires a website (I think). Affiliate marketing is most successful with a website, but you can pull it off with an email list alone. Websites are really cheap, and it only takes a little while to learn how to put one up. WordPress makes it super easy. Basically, I think the bare minimum to making money online is the ability to create a website. If the expense of a website is too much, then you'll find that nearly all of the tools for making money online are too expensive. Websites are one of the cheapest parts of this business.
