## Flattening
1. Satisfying demand - The pocket of viewers your video was performing well within may have been served.
2. Competition - Perhaps YouTube have found other videos that are satisfying the audience more than your one.
3. Time Relevant - Your video may become less relevant over time, e.g a video covering a current event, leading to a flatline in performance.
4. Core audience focused -Â Your video might have been really interesting to your most dedicated viewers, but lacked appeal as it was shown to a wider viewer base.
