A view is counted almost immediately
A view registers within the first moment or two of a video appearing on someone's screen, whether or not they kept watching. A high view count with a low average watch time usually means a video is earning the initial swipe-in but losing viewers immediately after. Worth investigating, not celebrating.
Average watch time and completion rate are the real signal
How much of a video people watch on average, and what share watch it all the way through, reflects genuine performance far more than the raw view count. A shorter video with a high completion rate does more for a channel than a longer one people stop watching partway through.
Shares indicate content people wanted someone else to see
A share means someone found a video worth sending to a specific person, which reflects a stronger reaction than a like. Tracking which videos get shared, not just liked, tends to reveal what content is genuinely resonating versus what is only being scrolled past and tapped.
