1. Algorithmic Demotion

Low Engagement

• Watch Time: Videos with low watch time and high drop-off rates are less likely to be promoted.
• User Interaction: Low levels of likes, comments, shares, and subscriptions can signal to the algorithm that the content is less engaging.

Policy Violations

• Content ID and Copyright Claims: Repeated copyright violations can lead to videos being demoted.
• Community Guidelines: Content that skirts the edges of YouTube's guidelines may be less likely to appear in search results or recommendations.

2. Limited Visibility

Sensitive Content

• Age-Restricted Videos: Content flagged as inappropriate for younger audiences can be age-restricted, reducing its visibility.
• Controversial Topics: Videos on controversial topics might be demoted to avoid spreading misinformation or harmful content.

Demonetization

• Ad Suitability: Videos that are demonetized for not being advertiser-friendly often see a decrease in views.
• Limited Features: Demonetized videos may be excluded from recommendations or search results.

Live Chat Moderation
