How to Write a Proper Video Description and Tags

Most creators spend hours filming and editing, then fill in metadata in a minute right before publishing — just so the field isn't empty. That's a costly mistake. Tags and description are how YouTube's algorithm understands what your video is about and who to show it to. Well-crafted descriptions and tags push videos into search and recommendations; poor ones leave them without impressions regardless of how good the footage looks. Let's break down how to fill these fields correctly, with the specific limits you cannot ignore.

Fill order: title → tags → description

Start with the title, then move to tags, and only then to the description. The logic: the title sets the primary keyword, tags reinforce it with variations, and the description builds out the semantic context around that keyword. Writing in reverse order makes it easy to lose focus and dilute the topic across irrelevant queries.

The whole point of metadata is simple: give the algorithm a clear signal about what your video covers. The more consistently your title, tags, and description align, the more confidently your video ranks.

Title ≤63 characters

The title carries your primary keyword and is hard-capped at 63 characters. That's not a suggestion — it's a technical limit: anything longer gets truncated with an ellipsis in search results, on thumbnails, and in recommendations, so viewers never see the second half of your message. Put the primary keyword at the start so it survives any cutoff and catches the eye first.

A useful trick is to open with question words like "how," "why," "what," or "how much." These titles index better in Google and drive external search traffic. Tools like VidIQ include a truncation simulator that shows how your title looks on different screen sizes so you don't go over the limit.

Description: 500 characters, timestamps, and a link in the first 150

The description should be at least 500 characters. That's the volume of text the algorithm scans for keyword forms, related queries, and the video's overall context. A two-line description cuts your SEO potential in half.

A description that works:

• First 150 characters — the most valuable real estate. It's visible without clicking "Show more," so this is where you put your primary link: to your website, lead magnet, or next video.
• Main body — 2–3 paragraphs covering the topic in the viewer's own words, with natural keyword and synonym placement. No stuffing: the text should read naturally.
• Timestamps — required. They give viewers navigation and send an extra text signal to the algorithm about chapter content. The first timestamp is always 00:00.
• Internal links — links to your other videos and playlists to keep viewers on your channel.

Timestamps matter most for long-form videos: they turn a solid block of footage into a structured answer to a query and increase the chance of ranking for sub-topic searches.

Tags: up to 500 characters and what to put in them

Tags are capped at 500 characters total. This field is for:

• the video's primary keyword in its exact form;
• long-tail variants and synonyms of that keyword;
• branded tags — your channel name, your name, your series title;
• competitors' keywords for topics that are already getting views.

Tags are where the "triple-match" technique lives: your primary keyword appears in the title, description, and tags at the same time. VidIQ's tag inspector shows a #N badge — your current search rank for each query. If your video is in the top spots for a target tag, you have steady search traffic.

Don't fill the field with junk tags for the sake of volume — a scattered set of queries confuses the algorithm more than it helps.

Common mistakes in descriptions and tags

• Empty or single-line description. The algorithm has nothing to work with and the video drops out of search.
• Title longer than 63 characters. Half the text gets cut and the keyword is lost.
• Link at the bottom of the description. No one will see it without expanding — it belongs in the first 150 characters.
• Same metadata on every video. Each video targets its own query; copy-pasted descriptions destroy your semantics.
• No timestamps. You lose both viewer navigation and the text signal for the algorithm.
• Tags that don't match the title. No triple-match — the topic signal gets diluted.

Hashtags, pinned comment, and localization

Beyond tags and descriptions, a video has adjacent text assets that creators often overlook. The first few hashtags from the description are pulled up above the title and are clickable — base them on your primary keyword and closely related queries, but don't overdo it: YouTube ignores hashtag overload. Right after publishing, pin a comment from the channel — with the title, links, and a question for the audience. It catches early engagement signals and gives the keyword one more placement. If the channel targets multiple languages, localize the metadata — translate the title and description so the video can be found by queries in each language. Each of these details moves the needle only a little, but together they give your video's SEO a meaningful boost.

Special case: descriptions and tags for Shorts

The rules for vertical videos are similar, with one caveat: links and tags in Shorts are not clickable, so a "click the link in the description" call to action simply doesn't work here — conversions from Shorts are driven differently, through a pinned comment and links to long-form videos. Keep the Shorts description under 500 characters, and select tags the same way you would for a regular video. Thumbnails for a Shorts series are usually consistent, with only the title changing.

How Goutub speeds this up

Filling in YouTube tags and descriptions manually — following every rule and staying within every limit — is slow and error-prone. Goutub handles this automatically during the packaging step. The platform generates a full YouTube package for each video: a title with the primary keyword, a description of the right length, 20–30 tags, hashtags, and timestamps derived from the actual voice-over — meaning they reflect exactly what's said in the video, not guesswork. All you need to do is review and optionally edit the text, not build metadata from scratch. Every video ships with properly formatted fields, ready for indexing.
