YouTube counts views through a combination of automated algorithms and manual review processes to ensure accuracy and prevent fraudulent view counts. Here’s a simplified overview of how YouTube counts views:

1. User Interaction: When a user clicks on a video and starts watching, this interaction is registered as a view.
2. Time Threshold: To be counted as a view, the user typically needs to watch a significant portion of the video, often around 30 seconds. This threshold helps filter out accidental clicks or very short visits.
3. Unique Views: YouTube distinguishes between repeated views from the same user and unique views. Multiple views from the same user within a short period are often counted as a single view.
4. Verification: YouTube constantly monitors views for any unusual or suspicious activity, such as automated view bots or click farms. Invalid views are filtered out and not counted.
5. Real-Time Updates: YouTube provides real-time view counts, but these numbers may be adjusted as the platform reviews the legitimacy of views.
6. Freezing Counts: Occasionally, YouTube may freeze the view count on a video to conduct a manual review if it suspects fraudulent activity. Once the review is complete, the view count is updated accordingly.
