YouTube description best practices for the lines above Show more
YouTube description best practices put the outcome and the keyword in the first two lines, then chapters, a CTA, and three hashtags. Write that by hand or generate the draft with iutu.be in YouTube Studio, then paste real timestamps.

Templates rot when every video starts the same
If 80 videos begin with the same three social links, you have trained viewers to skip. Rotate the hook. Keep links below the fold.
AI is useful for structure (hook, keywords, chapters, hashtags). You still own facts, timestamps, and affiliate disclosures.
Description structure that YouTube can parse
- 1
Line 1–2: outcome + keyword
“Fix a squeaky office chair in 10 minutes without WD-40.” That is a description start and a title cousin.
- 2
Paragraph 2: who it is for
Beginner, renters, left-handed guitarists — one sentence.
- 3
Timestamps
00:00 format. iutu.be inserts placeholders; replace them with real times.
- 4
CTA + 3 hashtags
Subscribe with a reason. End with three specific hashtags, not a wall of trends.
Legal and quality notes
- Disclose affiliates where required.
- Do not keyword-stuff competitor brand names you never mention on camera.
- Shorts: still write a real first line; those videos get searched too.
The limits YouTube sets
A few rules come from YouTube itself, and they decide what the structure can be:
- A description can be up to 5,000 characters. Only the first lines show before a viewer taps “more”.
- Chapters appear when the description has at least three timestamps in order, the first one is 0:00, and each chapter is at least 10 seconds long.
- YouTube can show the first three hashtags above the title. With more than 60 hashtags, YouTube ignores all of them.
- Links in the description are clickable; put the ones that matter after the opening lines, not before them.
A filled-in example
For a video titled “15-Minute Garlic Butter Pasta (One Pan)”, an example description following these practices:
Garlic butter pasta in one pan, ready in 15 minutes with five ingredients. I show the exact heat and timing so the garlic turns golden, not bitter.
- 0:00 What you need
- 0:45 Cooking the pasta in the pan
- 4:10 Garlic butter without burning it
- 8:30 Finishing and serving
- Then one line asking viewers to subscribe for a new 15-minute dinner each week, your links, and three hashtags: #garlicbutterpasta #onepanmeals #15minutemeals
YouTube video description best practices
YouTube video description best practices are the same on a tutorial and a review: the outcome in the first two lines, the keyword in the first 25 words, chapters with real timestamps, and three hashtags that match the footage. A template helps. A generator writes the first draft in Studio.

The iutu.be extension adds Enhance buttons next to title, description and tags. Review the rewrite, apply it, publish. Free every day — or $25 once for unlimited.
Frequently asked questions
What are YouTube description best practices?
Hook in the first two lines, the keyword in the first 25 words, timestamps, a CTA, and three hashtags. Paraphrase the spoken promise. Do not paste the transcript.
How many hashtags?
Three strong ones at the end. YouTube may show the first three above the title.
Can iutu.be write the whole description?
Yes, then you edit timestamps, links, and disclosures. That enhance counts as one daily free optimization.
