Pro Tips for YouTube Descriptions

- Front-load a hook in the first 2 lines before the "Show more" cutoff.
- Add timestamps to boost watch time and earn key moments in search.
- Include a clear call-to-action to subscribe, like, and comment.
- End with 3–5 relevant hashtags to improve discoverability.
Frequently Asked Questions
A good YouTube description is typically 200–350 words. The first 1–2 sentences (about 100–150 characters) are most important because they appear in search results and above the fold, so put your main keyword and hook there.
About the YouTube Description Generator
Your video description does far more than describe your video — it tells YouTube's algorithm what your content is about, appears in search results, and gives viewers reasons to watch, subscribe, and click your links. Our free YouTube Description Generator uses AI to write complete, SEO-optimized descriptions in seconds, so you never start from a blank box again.
Just describe your video, add your target keywords, choose a tone and length, and optionally drop in timestamps, links, and a subscribe CTA. The AI weaves everything into a natural, scannable description with your main keyword placed exactly where it matters most — the first couple of sentences.
