Viral Autopsy: Why a Video Held (or Lost) Attention
Views are a lagging indicator. The autopsy reads the mechanics underneath them — which hook archetype fired, how the structure paced, and what template you can reuse on purpose.
The short answer
A viral autopsy is a mechanical teardown of a piece of content that already performed — or already flopped — to find why. ContentCraft's Viral Autopsy is free with no signup: paste a post or video script and it classifies the hook against six named archetypes (Contrarian Take, Curiosity Gap, Number List, Personal Story, Hot-Take Question, Myth Bust), maps the content's structure segment by segment, analyses the pacing, and extracts the reusable template hiding inside it. The report is shareable — the point is not a score, it is a named mechanism you can run again on purpose instead of hoping to get lucky twice.
What the autopsy actually reads
The hook, with receipts. Every archetype match shows why it fired — the trigger phrases and patterns the classifier matched, in the open, so you can disagree with it. A hook that matches no archetype is itself a finding: it usually means the opening is doing logistics ("hey guys, welcome back") instead of making a promise.
The structure map. The post is segmented into its functional parts — hook, setup, escalation, payoff, call to action — so you can see whether the piece earns its length or front-loads everything into the first line and coasts.
The pacing. Long unbroken stretches lose people even when the words are good. Pacing analysis shows where the density changes, which is where attention actually leaks.
The template. The autopsy's real output: the reusable skeleton of this piece, abstracted so your next post can run the same mechanics on a new topic. A viral post you cannot decompose is a lottery ticket; decomposed, it is a format.
Held vs lost: the two signatures
| Signal | Held attention | Lost attention |
|---|---|---|
| Hook | Matches a named archetype; promise made in line one | No archetype match; greeting or throat-clearing first |
| Structure | Escalation before payoff; the gap opens before it closes | Payoff given away in the hook, nothing left to stay for |
| Pacing | Density varies; short beats after long ones | One unbroken register from start to finish |
| Ending | The loop closes and hands the viewer a next step | The piece simply stops |
Run yours
The autopsy is the free core job of ContentCraft: run a Viral Autopsy on your best post and your worst — the contrast teaches faster than either alone. Then write the next one from the extracted template, and autopsy that too. That loop — publish, autopsy, extract, reuse — is the whole discipline. Then give the extracted format an audience and a title: the Traffic Machine turns one offer into a day-by-day traffic plan, and ClickBaiter pressure-tests the titles you wrap around the format. Pair it with the seven hook frameworks when a hook matches no archetype and you need a stronger shape, and see the full fleet at Ingenious AI.
Questions
What is a viral autopsy?
A mechanical teardown of a published post or video script to find why it held or lost attention. ContentCraft’s Viral Autopsy classifies the hook against six archetypes, maps the structure, analyses pacing, and extracts the reusable template — free, no signup.
What are the six hook archetypes?
Contrarian Take, Curiosity Gap, Number List, Personal Story, Hot-Take Question, and Myth Bust. Every match shows the trigger phrases and patterns it fired on, so the classification can be checked rather than trusted.
Do I need an account to run a Viral Autopsy?
No. The autopsy at /viral-autopsy is free with no signup, and the report is shareable by link.
What should I autopsy first?
Your best performer and your most disappointing post, back to back. The held-versus-lost contrast — archetype match, structure, pacing — teaches the mechanics faster than either report alone.
What do I do with the extracted template?
Write your next post on a new topic using the same skeleton: same archetype, same structure beats, same pacing shape. A decomposed hit becomes a format you can run deliberately instead of a lottery ticket.
