YouTube Description Generator
Paste your title + a 2-line summary — get a full YouTube description with a killer hook, keyword-rich paragraphs, CTA and 10 hashtags. Optimized for search and the 157-char preview.
How to write a YouTube description that actually ranks
The first 157 characters of your description are the search snippet and the 'see more' preview — that's where you win the click. YouTube uses the full description as a ranking signal for search, related videos and Suggested, so keyword density matters. But stuffing kills it: aim for your primary keyword 2-3 times, LSI variants 2-3 more, and natural language throughout. Add a strong hook line, a benefits-driven paragraph, a chapters placeholder (fill in timestamps after upload), a CTA to your site or free product, and 3-10 hashtags. This generator produces exactly that shape in your language.
YouTube description generator FAQ
How long should a YouTube description be?+
Between 200 and 500 words for long-form, 100-200 for Shorts. YouTube supports up to 5,000 characters, but only the first 157 show without clicking 'more'. Front-load the hook and primary keyword.
Do YouTube descriptions help SEO?+
Yes. YouTube reads the description to understand your video for search, related videos and Suggested feed. Include your primary keyword 2-3x, related keywords naturally, and match the language of your title.
Should I add hashtags to my YouTube description?+
Yes, 3-10 hashtags at the end. The first 3 show above the title. Use one broad tag (#youtube, #shorts), one niche tag and one specific to the video.
How do I add chapters / timestamps?+
The generator inserts a chapters placeholder — fill in real timestamps after you edit your video. Format: '0:00 Intro' on separate lines. First chapter must start at 0:00 and you need at least 3 chapters, each ≥ 10 seconds.
