YouTube Description Generator

A YouTube description should name the topic in the first two lines. Then put links. People and search both read the top. Timestamps can wait.

The tool

Use this after the title passes. Write the first 150 characters as the whole pitch. Add the demo or article link with a UTM.

Topic first. Links after

Description

Why it helps

Why you need a YouTube Description Generator

YouTube shows only the start of the description until someone taps Show more. The topic and the link belong there.

Links in the description should use UTMs. If the push is google-in-demo-exact-2026q3, keep that campaign and set utm_source=youtube.

Keywords once, in a normal sentence. The description is not a tag soup.

HOOK, BODY, NEXT STEPHOOK, BODY, NEXT STEPHookwhy pauseBodythe offerCTAthe URLWrite for the box you will paste into. LinkedIn is not X.Use the same utm_campaign as the ads, with the right source.
A vibe with no link is a scroll.

When

When to use it

  • Title is locked and the description is still empty.
  • When the only link is in a comment that will get buried.
  • When you republish a webinar replay and the old Zoom link is still in the text.

How

How to use it

  1. 1Sentence one: what the video is. Include the main topic.
  2. 2Sentence two: what to do next, with the URL.
  3. 3Then chapters, extra resources, and a short about line.
  4. 4Paste into YouTube. Confirm the first two lines still work before Show more.

Example

Example: description for the Acme demo video

Title already: Campaign Names and UTMs That Roll Up | Acme Demo. Landing page is https://acme.com/demo.

You put in

Topic
campaign names and UTMs
Offer
30-minute product demo
Link
https://acme.com/demo

You get

See how one campaign name works in Google Ads, the UTM, and your Monday report.
Book a 30-minute Acme demo (free to browse): https://acme.com/demo?utm_source=youtube&utm_medium=video&utm_campaign=google-in-demo-exact-2026q3

0:00 Why names break reports
1:10 Hyphens and lowercase
3:00 Build the UTM

The first two lines work without Show more. The URL uses a clean UTM. Chapters are extra. If the description started with a channel trailer pitch, the demo link would sit below the cut.

Result

What this changes for you

The watch page explains the video. The link is trackable. You stop a blank description or a pasted blog dumped in a block.

Common mistakes

  • A wall of keywords with no sentence.
  • The first link going to the homepage or a expired webinar.
  • Putting the only CTA after five paragraphs of bio.
  • No UTM, then wondering why YouTube traffic is Direct in GA4.

FAQ

YouTube Description Generator FAQ

What should a YouTube description generator put first?

The topic and the next step. YouTube hides the rest behind Show more. Links and timestamps can follow.

How long can a YouTube description generator run?

YouTube allows up to 5,000 characters. You do not need them. Write two strong opening lines, then extras.

Should a YouTube description generator include a UTM link?

Yes if you want the click in GA4. Use utm_source=youtube, a medium like video, and the same campaign name as the rest of the push.

Is a YouTube description generator the same as a meta description tool?

No. A meta description is for Google search snippets (~150–160 characters). A YouTube description is on the watch page and can hold links and chapters.
