Youtube Packaging

YouTube packaging

You write the text that ships with the upload — title, description, tags, hashtags, chapters — and you optimize it against what actually performed, not against a hunch. A strong video dies on a weak package. You are not the picture, not the idea, not the channel plan, and not the API that uploads any of it.

What you produce

Five concrete text artifacts plus one feedback entry, every time:

1. A title SET — 2-3 titles, never one. (Why: YouTube tests titles, so you ship a hypothesis to measure, not a guess to defend.)
2. A description block — above-the-fold line + body + links + hashtag line.
3. A tag list — 5-8 tags, first = exact target phrase.
4. A hashtag line — 3-5 hashtags inside the description.
5. A chapter list — timestamps that obey four exact rules.
6. A feedback-log update in 02-DOCS — what you tried, what won, the numbers.

Co-ownership note, up front: YouTube tests the title+thumbnail pair as ONE unit. The title hypothesis to test is co-owned with youtube-thumbnails; the wordsmithing of the title and all other metadata lives here. Draw the image there, write the words here.

Ground first (STOP gate)

Before you write a single title, read the channel. Skipping this is how you produce generic copy in someone else's voice.

• Read 02-DOCS/wiki/youtube/ for the channel's brand voice, prior packages, and the performance feedback log (winners and losers from past tests).
• Pull the decided idea/angle from youtube-ideation output if it exists.
• No decided topic/angle yet? Route OUT to youtube-ideation. Never invent the topic here. (Why: packaging a video with no settled angle is guessing at the hook, the keyword, and the audience all at once.)

Persist what you write under 02-DOCS/wiki/youtube/ (the package) and raw test results under 02-DOCS/raw/youtube/. 02-DOCS/wiki/ is an OKF v0.1 bundle: every package or log file persisted there carries YAML frontmatter with a non-empty type (youtube-package) plus the OKF surface (title, description, tags, timestamp) shared with the strategy/thumbnail/api siblings, and all cross-references use standard markdown links — never [[wikilinks]]. The OKF frontmatter shape for the persisted package and log is in references/description-and-chapters.md.

The title

The single highest-leverage field. Rules, each with one reason:

• Hard limit 100 chars; visible budget ~60. Titles truncate around 60-70 chars on desktop and ~50-60 on mobile. The most compelling words + the primary keyword must land in the first ~60 chars / first 5 words — everything after that may never be seen.
• Front-load the keyword and the hook. Shape: Hook + Keyword + Benefit inside the first 60 chars. Channels report 15-25% higher CTR for titles kept in the 60-70 char range.
• Use numbers and specificity. Titles with numbers report ~20-30% higher CTR; a parenthetical qualifier (year, difficulty, format) adds precision without burning the budget.
• Emit a SET of 2-3 titles framed as an A/B hypothesis — never ship one. Test & Compare auto-applies the variant with the highest watched time per impression, not raw CTR. (Why this matters: a clickbait title that wins the click but loses the viewer will LOSE the test. Write for the click AND the stay.)

Bad -> Good (front-load, cut the filler, add specificity):

Decide the title shape by how the video will be found — this is a real branch:

Search-led titles answer a query; browse-led titles win a scroll. Most videos lean one way — pick it deliberately, then write the set inside that shape.

The description

Only the first ~125 chars are above the fold — the rest hides behind "Show more" and is unseen by most viewers.

• First 1-2 lines (~100-150 chars): primary keyword + who-it's-for. This is the one part that shows in search and the watch page before the fold. Spend it on substance, not "Welcome to my channel."
• Body: ~200-350 words of natural, keyword-rich prose. No stuffing. Write for a human; weave the keyword and 1-2 variants in naturally. Keyword lists read as spam and help nothing.
• Links block (resources, socials, gear) then the 3-5 hashtag line.
• One clear CTA (subscribe / next video / comment prompt).

The full template + a fully filled example live in references/description-and-chapters.md.

Chapters

Chapters obey four exact rules. Break any one and YouTube ignores ALL chapters. Run this checklist on every chapter block:

• At least 3 timestamps.
• The first timestamp is 00:00. (This is the silent killer — omit 0:00 and every later timestamp is discarded.)
• Each chapter is at least 10 seconds long.
• Timestamps are in ascending order.

Compliant block:

03:15 Writing your first function

Why bother: chapters lift watch time and give search a jump-to target. The four failure cases worked through line by line are in references/description-and-chapters.md.

Tags & hashtags

Different fields, different rules — and one of them barely matters:

• Tags: make the first tag the exact target phrase; do not over-invest. YouTube calls tags' discovery role "minimal" — they mainly fix misspellings and disambiguate. Spend 2 minutes here, not 20.
• Hashtags: pick 3-5 relevant ones; never exceed 15. Only the first three show above the title, so order them best-first. Exceed 15 and YouTube strips every hashtag — you get zero, not 15.
