Write video descriptions that rank and convert
A YouTube description does two jobs at once: it gives the algorithm context about your video, and it gives viewers a reason to take the next action. Most creators waste it by pasting the same generic paragraph on every upload. The first two or three lines — the part shown before the "Show more" cut — are prime real estate that should reinforce your hook and include your primary keyword.
Below the fold, a strong description adds a short summary, timestamps for longer videos, relevant links, and a clear call to action. Timestamps in particular can earn you key-moment placements in search and keep viewers watching by letting them jump to what they need.
This tool builds a complete, structured description from your topic — opening hook, keyword-rich summary, suggested timestamps and a call to action — so you never publish with an empty or copy-pasted box again.
How to use this tool
- 1
Enter your video details
Add the title, the main topic and any links or offers you want included.
- 2
Generate the description
The AI writes an opening hook, a keyword-aware summary and a call-to-action tailored to your topic.
- 3
Add timestamps
For videos over a few minutes, drop in chapter markers so viewers — and YouTube — can navigate your content.
- 4
Paste and publish
Copy the finished description into YouTube Studio and adjust any links or CTAs to fit your channel.
How the result is calculated
The description is produced by a language model from your topic and any keywords you supply, structured to the shape the video optimizer scores for: an opening that restates the topic, body paragraphs, and space for timestamps and links.
It does not fetch your video, read your transcript, or see your channel. Everything in the output comes from the prompt you provided.
How to read the result
The first two lines are the part that matters most — they are what shows above the fold before a viewer expands. Edit those by hand even when you keep the rest.
Generated timestamps are placeholders. Replace them with your real chapter marks; wrong timestamps are worse than none.
What this tool cannot tell you
- —It cannot verify any factual claim it writes about your video.
- —It does not know your links, affiliate disclosures or sponsor obligations. Those are yours to add.
- —Hashtag suggestions are generated, not measured against current search volume.
Tips & best practices
- ✓Put your primary keyword in the first sentence — that text is weighted more heavily and is visible before "Show more".
- ✓Use timestamps (chapters) on any video longer than about four minutes to unlock key-moment search results.
- ✓Keep links minimal and relevant; a wall of links looks spammy and dilutes your main call to action.
- ✓Write for humans first. Keyword-stuffed descriptions read badly and can be penalised.
- ✓Reuse a consistent footer block (socials, gear, disclaimers) but always customise the top three lines per video.
Frequently asked questions
How long should a YouTube description be?+
There is no fixed rule, but 150–300 words is a healthy range. The first 2–3 lines matter most; the rest adds context, timestamps and links for viewers who expand it.
Do descriptions affect YouTube ranking?+
Yes, indirectly. YouTube reads your description to understand the topic and match it to searches. It will not rank a weak video on description alone, but a clear, keyword-relevant description helps the right viewers find you.
What are timestamps and why do they matter?+
Timestamps (chapters) split your video into labelled sections. They improve navigation, increase watch time, and can earn special "key moments" placements in Google and YouTube search.
Can I use the same description on every video?+
Reuse a standard footer, but always rewrite the opening lines and summary for each video. Duplicate descriptions give YouTube no unique signal and can look low-effort to viewers.
