I feel like we have different definitions as to what clickbait is - when I see a clickbait video, I can simply identify it by it's title and thumbnail, I've never needed to look at the like:dislike ratio to confirm that it's clickbait. What kind of videos do you find as clickbait?
An interview where they spend 30 minutes off-subject and 1 minute on-subject. A tutorial with 10 minutes of detailed explanation and a "now draw the owl" step buried 3/4 of the way through. A thumbnail that promises a level of complexity, sophistication, or accomplishment that winds up never actually happening in the video.
Content farms aren't the only ones in the clickbait game these days.
