šŸ“‹ About YouTube Video Descriptions

Your video description is prime SEO real estate. YouTube's algorithm scans the first 200 characters to understand your content. A well-written description with timestamps, keywords, and CTAs can significantly boost your video's ranking and watch time.

šŸ“ First 200 Chars

YouTube shows the first 2-3 lines above the fold. Put your most important keywords and a hook here — this is what viewers see before clicking "Show more."

ā±ļø Timestamps

Chapters help viewers navigate and signal to YouTube that your content is well-structured. Include 3-8 timestamps for chapters to appear in search.

šŸ”— CTAs & Links

Always include a subscribe CTA, related video links, and social links. Descriptions with CTAs see 30% higher engagement on average.
