Video Description is the text that creators add below a YouTube video to explain its content, provide additional information, and include relevant links or resources. A well-written video description helps viewers understand what the video covers while giving YouTube additional context about the video's topic. Although descriptions are only one of many ranking signals, they support search visibility, accessibility, and viewer engagement when they accurately reflect the content.
Why It Matters
A Video Description gives viewers important information before and after they watch a video. It can answer common questions, provide links to referenced resources, include timestamps, and encourage further engagement without requiring viewers to leave the platform immediately.
A clear and relevant description also helps YouTube better understand the video's subject. Combined with the title, captions, spoken content, and viewer behavior, the description contributes to how YouTube categorizes and surfaces videos in search and recommendations.
How It Works
Creators write a description during the upload process or edit it after publishing. YouTube displays a shortened version beneath the video, with the full text available when viewers expand the description.
Content Summary
The opening lines should clearly explain what the video is about. Because only the beginning of the description is visible before expansion, the most important information should appear first.
Keyword Context
Descriptions naturally include relevant keywords and phrases that describe the video's topic. Keywords should fit naturally within informative text rather than being repeated excessively.
Links and Resources
Creators often include links to websites, products, related videos, playlists, or social media profiles. Resource links help viewers find additional information related to the video's content.
Timestamps and Chapters
Descriptions can include timestamps that create Video Chapters when formatted correctly. This allows viewers to navigate directly to specific sections of longer videos.
Calls to Action
Many creators use descriptions to invite viewers to subscribe, watch related videos, visit a website, or access downloadable resources. These calls to action should remain relevant to the video's purpose.
Updates After Publishing
Descriptions can be edited at any time. Creators often update links, correct information, add resources, or improve clarity without re-uploading the video.
Example
A creator publishes a tutorial titled "How to Edit Videos in DaVinci Resolve." The description begins with a concise summary of what viewers will learn, followed by chapter timestamps, links to downloadable project files, recommended editing tools, and links to related tutorials. Relevant keywords appear naturally throughout the description, helping provide context without excessive repetition.
Video Description vs Video Title
A Video Description provides detailed information about a video's content, resources, and context.
A Video Title is the primary headline that appears in search results, recommendations, and subscriptions. The title is designed to capture attention and summarize the topic, while the description expands on that information with additional details, links, and supporting context.
