Trending helps viewers to see what's happening on YouTube and in the world. Trending aims to surface videos and Shorts that a wide range of viewers would find interesting. Some trends are predictable, like a new song from a popular artist or a new film trailer. Others are surprising, like a viral video.
Trending isn't personalised and displays the same list of trending videos to all viewers in the same country, which is why you may see videos and Shorts in trending that aren't in the same language as your browser. However, in India, trending displays a list of results for each of the nine most common Indic languages.
In certain countries, popular Shorts may be highlighted on a shelf or a tab within the trending page, or you may see the Shorts listed as trending 
The list of trending videos is updated roughly every 15 minutes. With each update, videos may move up, move down or stay in the same position in the list.
What determines if a video is ranked on trending?
Amongst the many great new videos on YouTube on any given day, trending can only show a limited number. Trending aims to surface videos that:
- Are appealing to a wide range of viewers
- Are not misleading, clickbaity or sensational
- Capture the breadth of what's happening on YouTube and in the world
- Showcase a diversity of creators
- Ideally, are surprising or novel
Trending aims to balance all of these considerations. To achieve this, trending considers many signals, including but not limited to:
- View count
- How quickly the video is generating views (i.e. 'temperature')
- Where views are coming from, including outside YouTube
- The age of the video
- How the video performs compared to other recent uploads from the same channel
We combine these signals to produce a list of videos that showcases what's happening on YouTube, while being relevant to our viewers and reflective of the content on the platform. This means that the video with the highest view count on a given day may not be no. 1 on trending and that videos with more views may be shown below videos with fewer views.
We're very careful about the safety of what appears on trending, so we have filters to make sure that we don't show videos that contain excessive profanity, mature content or violence, or videos that are otherwise inappropriate, such as disparaging others in the community. In the US and other locales, we have staff involved as a final filter to ensure safety and appropriateness.
YouTube doesn't accept payment for placement on trending and doesn't favour specific creators. We don't include views from YouTube ads in selecting videos for trending. In most major markets, we make sure that at least half of the videos on trending come from creators who are primarily creating content for YouTube.
Privacy settings for trending videos
A video can only appear on the trending tab if its privacy setting is public. Certain videos may be hidden from the trending page if Restricted mode is turned on. Learn more about Restricted mode here
