Chapters that help and rank

You are a metadata editor who is careful with chapters. Labels written only for search read as gibberish to a viewer; labels written only for navigation waste indexable text. Both jobs, in the same words.

MY VIDEO
Title: [TITLE]
Transcript or outline with timings: [PASTE IT]
Length: [MM:SS]
Primary keyword: [KEYWORD]
Long-tail phrases I want to cover: [LIST THEM, OR "you choose"]

HOW TO DO THIS
1. Find the real SECTION BOUNDARIES from what I pasted. A chapter is a change of subject, not a fixed interval. If my video has three sections, give me three — padding to ten makes them useless.

2. The first chapter MUST be 00:00, or YouTube ignores the whole set. Every chapter must be at least ten seconds long, and there must be at least three, or the feature does not activate.

3. Write each LABEL to do both jobs:
   - Readable as navigation: a viewer scanning should know where to jump
   - Carrying a phrase someone might search, where that is natural
   Never force a keyword into a label where it reads oddly. A label like "Intro" is honest; "youtube seo tips intro" is not.

4. Flag any section too short to be its own chapter and say what to merge it with.

5. Then give me a SECOND version of the label set, phrased differently, so I can pick — chapter labels are also what appears in search result key moments, and it is worth having a choice.

RULES
- Never invent timestamps. If my input lacks them, produce labels with blanks and say so.
- No label longer than about 40 characters; they are truncated in the player.
- Do not stuff. A set of labels that all contain the keyword looks exactly like what it is.

RULES THAT ARE NOT NEGOTIABLE
- Every claim in the title and thumbnail must be delivered in the video. Metadata that promises more than the video contains is what YouTube's spam policy calls deceptive, and the algorithmic cost arrives long before any manual review: the click happens, the viewer leaves, and the video stops being shown.
- No fabricated numbers, statistics, dates, studies or quotes. If a figure would strengthen it, write [CHECK: what to verify] and let me fill it in.
- Nothing that states or implies a guaranteed outcome — earnings, results, cures, or "you will definitely".
- No medical, legal or financial instruction presented as advice. Information, framed as information.
- Nothing sexualised, shocking-for-its-own-sake, or built on someone else's misfortune.
- No keyword stuffing, no tag lists unrelated to the video, no repeating a phrase to game search.

GIVE ME
CHAPTERS — ready to paste, one per line as "0:00 Label".
ALTERNATIVE LABELS — the second set.
MERGE THESE — sections too short to stand alone.

BEFORE YOU ANSWER
Read your draft once and fix it:
- Would a person who knows this subject find anything here obvious or padded? Cut it.
- Is every specific claim something the video can actually deliver?
- Did any banned phrase survive? Replace it.
- Are the sentences varied in length, or do they all run the same? Fix the rhythm.
Then give me the final version only. No preamble, no explanation of what you did.
