Shorts Description: What to Write

A description won’t replace a hook and retention, but it helps viewers understand context faster and helps YouTube collect clearer topic signals. A good description is short, specific, and not a wall of hashtags. Below is a 3‑line structure, examples, and common mistakes.

Why a Shorts description exists at all

In the Shorts feed people rarely read the description fully, but it’s useful in three situations:

  • When a viewer opened the video from your profile or search and wants quick context.
  • When you run a series — the description helps connect episodes.
  • When the topic is narrow and you need to “hint” context (term, niche, format).

Important: if people swipe in the first seconds, the description won’t save the video. Fix hook and pacing first, then packaging.

Common description mistakes

  • A wall of text. Nobody reads 10 lines in Shorts, especially without structure.
  • Empty phrases. “Subscribe”, “hello”, “watch till the end” — no specifics.
  • Hashtag spam. 15–30 tags look noisy and rarely help.
  • Irrelevant tags. “Trending” tags not related to the topic confuse context.
  • Description doesn’t match the video. You write one thing, show another — it annoys viewers.

A 3‑line description structure

Universal template: context → value → tags. It’s short and clear.

  • Line 1 (context): what the video is about and for whom (one sentence).
  • Line 2 (value): what the viewer will learn/do + a mini checklist (1–2 items).
  • Line 3 (tags): 3–6 topic hashtags (and a series tag if relevant).

Description examples for different formats

1) “3 mistakes”

Line 1: “3 mistakes at the start of Shorts that make people swipe away.”
Line 2: “Check: first‑frame promise, pacing, and a clear ending.”
Line 3: “#Shorts #YouTubeShorts #retention #hook”

2) Step-by-step guide

Line 1: “How to turn a long video into Shorts — without losing the point.”
Line 2: “Structure: hook → context → 2 steps → conclusion.”
Line 3: “#Shorts #editing #content”

3) Before/after

Line 1: “One hook edit that increases completion.”
Line 2: “Before: ‘today I’ll explain’ → after: ‘3 reasons why…’.”
Line 3: “#Shorts #firstseconds #retention”

What to write in the first line (context) so it’s not “water”

The first line is not “hello” and not “subscribe”. It’s a short explanation of what problem the video solves. These formulas work well:

  • “If Shorts aren’t getting views — check …”
  • “3 reasons why …”
  • “How to do … in 30 seconds”
  • “One edit to …”

The more specific the first line is, the less likely the description looks like “marketing”, and the easier it is for viewers to understand what they’ll get.

How to write a description in 30 seconds (step by step)

  1. Write one promise (result or pain).
  2. Add 1–2 value items (steps, mistakes, checklist).
  3. Pick 3–6 tags for the topic (plus one series tag if you run a series).
  4. Check for spam. Remove generic words and anything that adds no meaning.

If your description doesn’t fit into 2–3 lines, it’s usually a sign that the video itself is overloaded. In Shorts it’s better to make two videos than one “about everything”.

How many hashtags to use (and which)

A practical range is 3–6. Simple logic: 1–2 topic tags, 1 format tag, 1 series tag (if any), and optionally #Shorts.

  • Topic tags: specific words that describe the video (“retention”, “hook”, “editing”).
  • Format tags: “mistakes”, “checklist”, “steps” — if that’s truly the format.
  • Series tags: one consistent tag for a series (for example, “ShortsBreakdown”).

Mini checklist for a good description

  • Short? 2–3 lines, no “novel”.
  • Has context? The topic is clear even with sound off.
  • Has specifics? “3 reasons”, “1 edit”, “2 steps” — not generic words.
  • Topic tags? 3–6, no spam and no irrelevant tags.
  • Matches the video? The description promise is delivered in the video.

Mini FAQ about Shorts descriptions

Below are short answers to the questions that often turn descriptions into either “water” or spam.

Do you need a long description?

Usually no. In Shorts, the description is short context: what it’s about and what the viewer gets. If you want to go deeper, make a series and signal it in one line (“Part 2 tomorrow”).

Do you need to repeat the keyword query?

One natural mention is enough. What matters more is specifics: numbers, steps, “mistake #2”, “check 3 points”. It reads like value, not keyword stuffing.

Should you add a CTA at the end?

If you add one — keep it soft: “save this”, “check the checklist”, “ask a question”. “Subscribe” works much better when you already have a series and viewers know what’s next.

Can you insert links?

Better to avoid external links and long link lists. In Shorts, clarity wins: 2–3 lines and relevant hashtags. If you need a next step, describe it in words (for example, “template in the next video”) without overload.

How to test changes faster

Descriptions are best tested together with packaging: title, first seconds, on‑screen text. But growth usually comes not from a “perfect description”, but from iteration volume: you make two hook versions, compare retention, and keep the best. When a draft assembles quickly (voiceover, subtitles, music, background), you test hypotheses more often and find a format that holds viewers.

To test description faster, keep the topic the same and change only structure: 1–2 lines of value + one CTA. In AdShorts AI Studio you get a video together with a draft description and hashtags — making it easier to run a series of tests.

Next tests after this guide

Treat “Shorts Description: What to Write” as one test in a Shorts loop: define the exact viewer problem, change one visible thing, publish a clean version, then compare retention and clicks before making the next edit.

Before publishing, write one hypothesis: what should improve and why. For a faster variant, open examples or build the next version in AdShorts AI Studio.

Quick FAQ for the next test

What should I test first after this Shorts Description: What to Write guide?

Make the viewer promise clear first, then test wording, subtitles and the ending CTA.

How do I know the change worked?

Compare one metric before and after the change: swipe-away rate for the opening, retention for the middle, and clicks or inquiries for the CTA.
