You are not stupid, because it is a bit odd. So, on YouTube, you make money from the ads that are played before/during/after/around your video.Now, on platforms like Instagram you don’t get paid by the platform itself, but if you have enough followers, brands will pay you to talk about their products (some brands I work with will do that) or you’ll use them more as a personal marketing tool that redirect people to your website, service, etc. (I am not sure about TikTok, I don’t go there, it scares me :D )
