A good YouTube description puts the main keyword and a one-sentence promise in the first two lines (that's all viewers see before "more"), follows with a short summary, chapters with timestamps, and links, and ends with one to three hashtags. Tags matter much less: add a handful covering your main keyword, variations and common misspellings.

Descriptions and tags are where most creators either write nothing or paste the same block on every video. Both leave views on the table, especially for podcasts and long talks, where the title can't say everything that's inside.

The limits you're working with

You won't hit the description limit writing a good one. The number that matters more is two: the first two lines, which show in search results and above the "more" link.

What to put in the first two lines

Treat the first two lines as a second title. Say what the viewer gets, and use the phrase people would search for.

• Weak: "In this episode we sit down with Priya to talk about a bunch of stuff!"
• Better: "How to price freelance design work: Priya Nair explains the day-rate formula she used to double her income in a year."

Don't open with links, sponsor reads or "subscribe!" Those push the useful part below the fold.

A description template you can copy

``` [One sentence: what the viewer learns or gets, with the main keyword.] [One sentence: who's in it or why it's worth watching.]

[2–4 short paragraphs summarising the video in plain words. Use the words people search for, naturally. This is also where related topics go.]

Chapters 0:00 Intro 2:15 [Topic one] 9:40 [Topic two] ...

Links [Guest's site, resources mentioned, your newsletter, the full episode on other platforms]

hashtag1 #hashtag2

```

For podcasts, the summary paragraphs are where you capture searches for the guest's name, their company, and the specific topics you covered. Titles can't hold all of that.

Chapters belong in the description

Timestamps in the description create chapters on the progress bar, and they're one of the most useful things you can add to a long video. The rules are strict (start at 0:00, at least three, each at least 10 seconds), so we wrote a separate guide on adding chapters and timestamps to YouTube videos.

How much do YouTube tags matter?

Not much. YouTube's own help says tags play a minimal role in discovery, and are mainly useful when your topic is commonly misspelled. Your title, description and the video itself do the heavy lifting.

So spend two minutes on tags, not twenty:

• Your main keyword ("podcast pricing").
• Two or three variations ("how to price a podcast", "podcast sponsorship rates").
• The guest's name and show name.
• Any common misspelling of a name or brand.

What goes wrong: stuffing 40 loosely related tags. It doesn't help, and filling tags with misleading terms can break YouTube's spam policies.

Writing from the transcript is easiest: here's how to get the transcript of a YouTube video.

Hashtags: one to three is plenty

Hashtags in the description are clickable, and YouTube shows up to three above your title. Use one to three that genuinely describe the video; the hashtag generator builds them from your topic. Keep well under 60, since YouTube ignores all hashtags on a video that has more than 60.

Write it from the transcript, not from memory

The best descriptions use the words actually said in the video. That's also where the search terms are, because your guest described their topic the way people talk about it.

If you've got a transcript, skim it for the three or four ideas that stood out and the specific phrases used. Build the summary from those. Ten minutes, and it's more accurate than anything written from memory.

Add chapters from the same transcript while you're at it. Then cut the best moments into Shorts: ClipFlame does that from the same file and schedules them, which is the core of repurposing one video into a week of content.

Descriptions for YouTube Shorts

Shorts show the title over the video, and most viewers never open the description. Keep Shorts descriptions short: one line of context, a link to the full video if relevant, and one or two hashtags. Put your effort into the clip's first second instead. See how to get more views on Shorts.

For the clips that point back to the full video, see how to make YouTube Shorts.

Common questions

How long should a YouTube description be?

Long enough to explain the video and hold your chapters and links. For a long podcast or tutorial, 150 to 400 words is common. For a Short, one or two lines.

Should I use a YouTube description generator?

A generator is a good starting point if it works from your actual transcript. Always edit the result: check names, remove anything the video doesn't cover, and make sure the first two lines sell the video.

Do tags help YouTube SEO?

A little, mainly for misspellings. The title, description, captions and how viewers respond to the video matter far more.

Where do I find tags on YouTube?

In YouTube Studio, open the video's details and click Show more. The Tags field is there.
