Several years ago I saw an ad on Tumblr (I know, I know), for a strange meme site. After seeing several hundred of these ads, I got curious about how it could be profitable to run such nonsense and clicked. Content that was just funny enough to keep me scrolling mixed with ads. It turned out, that was a site run by an Israeli ad-tech media company that used algorithms to find out how many ads they could could put in while maintaining attention, a sort of google ads style auction running on the page to determine if it should add an ad or a meme to the page next. Linkedin has public research doing the same type of thing.
