> Why does that content get ranked highly?

Search engines only show a snippet of the content and that always looks convincing. It's the whole content that is off and, unfortunately, a few seconds/minutes can pass before you realize it (If you ever do).

Search engines track that. It's what a "long click" means. If you click a result, then return fairly fast and keep searching or clicking other links, they infer low quality (for that query at least).

Well, and Google's proxy read of "quality" might have flawed assumptions. A concise page where you get what you need and leave quickly might read as "high bounce rate".
