Views versus unique viewers

A view is a play of the video. A unique viewer is a person who played it, however many times. Most platforms report both, and reading only the first is the most common analytics mistake in video.

The gap between the two numbers carries information. A video with many views and few unique viewers is being rewatched, which for a product demo or a technical explanation is usually a good sign and for a thirty-second message is usually a sign of confusion. A video with views and unique viewers almost equal was watched once each and then left alone.

What counts as a view varies enough between platforms to make cross-platform comparison meaningless. Some count a play the moment the player loads; some require a few seconds; some require a proportion of the video. Before comparing a number to anything, find out what the platform means by it.

Neither number says anything about whether the video worked. Both measure arrival, and arrival is a function of the subject line, the thumbnail and the sender — not of the recording. Watch time and completion measure the recording.

Automated traffic distorts both numbers, and more than most people assume. Link scanners in email security products open URLs to check them, some clients prefetch pages, and previews generated in chat applications can register as arrivals. A small baseline of views that nobody made is normal, which is another reason to treat watch time as the number that means something.

Neither figure survives a change of definition, so record what your platform counted at the time. A number that moves when a vendor adjusts its threshold is not a change in your audience, and teams that keep a note of the definition alongside the figure avoid a whole category of false conclusion.
