Three Seconds, and Autoplay Does the Rest
Video in the Facebook feed plays automatically, without sound, as it enters the viewport. If someone scrolls slowly enough for three seconds to elapse, that registers as a view whether or not they looked at it.
Compare that with the alternatives. YouTube requires a meaningful portion of the video. TikTok counts on play but the feed is full-screen and deliberate — you are watching, not scrolling past. Facebook is the only major platform where a substantial fraction of the view count can be attributed to people who never chose to watch.
None of this makes the number worthless. It makes it a different kind of number: a reach and social-proof metric rather than an attention metric. Treat it as "how many people this video got in front of", not "how many people watched it".
