YouTube Shorts reward retention curves, not just hooks. A strong opener with a flat middle still gets buried, because the algorithm watches the percentage of the video your viewer actually finishes: the reframe around 8 seconds, the payoff near 25, and whether they reach the end card at all. These 12 prompts force a designed retention curve at named timestamps instead of a vague “make it engaging,” plus a subscribe CTA that is earned by the time you ask for it.
For the opening 3 seconds specifically, pair these with TikTok hook prompts and viral shorts hook prompts.
TL;DR
- Shorts can run up to 3 minutes (since the October 2024 cap change), but 30-60 seconds remains the sweet spot for views vs. completion as of June 2026. Sub-25-second clips win the highest completion rate; 50-60-second clips tend to pull the most raw views per clip.
- Write to timestamps, not adjectives. Every prompt below names where the hook ends, where the reframe lands, and where the payoff drops.
- Place the subscribe CTA only after a real micro-payoff. “Subscribe” before any value lands wrong and tanks the close.
- Run these on a strong instruction-follower: Claude Sonnet 4.6, GPT-5.5, or Gemini 3.1 Pro all handle the timestamped structure well.
- Replace every
[bracketed]placeholder with your specifics before sending.

Which length to write for (2026 data)
Shorts retention is measured as the share of the clip watched, so a 60-second Short watched for 45 seconds scores 75%. Pick the length that matches your goal, then write the curve to hold it.
| Length | What the data shows (2026) | Best for |
|---|---|---|
| 15-25s | Highest completion rate; ~68% of all Shorts views consumed sit in this short bucket | Single punchy idea, loops |
| 30-45s | Balanced views and completion; common viral range | Educational, listicle, explainer |
| 50-60s | Most raw views per clip; ~76% average completion in third-party studies | Story arcs, tutorials, repurposed long-form |
| 60-180s | Allowed, but completion drops fast without a tight curve | Deep tutorials only |
How to run these prompts
- Pick the template that matches your format below.
- Fill in every
[placeholder](topic, persona, niche, tone). - Paste into Claude Sonnet 4.6, GPT-5.5, or Gemini 3.1 Pro — all follow timestamped structure reliably and run on free tiers for occasional use.
- Read the script out loud against a timer. If you blow past a marked timestamp, cut words, not points.
- For the first 3 seconds, regenerate with prompt #11 until one hook makes you want to keep watching.
1. 30-second educational short
Write a 30-second YouTube Short script on "[topic]" for audience [persona].
Output: 3-second hook, 18 seconds of payoff (3 micro-points), 9-second close
with sub-CTA. Include on-screen text cues at each 3-second mark.2. 60-second tutorial short
Write a 60-second Shorts tutorial on "[task]".
Output: 4-second hook, 4 micro-steps (~12 sec each), 4-second recap with sub-CTA.
Each step needs an action verb + a visual cue. End with "now subscribe for [next thing]".3. Retention-curve script
Write a 45-second Shorts script designed for a retention curve.
Output: hook (0-3s), reframe (8s), payoff 1 (15s), tension (25s), payoff 2 (35s),
close (42s). Mark each timestamp with what happens visually.4. Faceless-channel narration
Write a 40-second Shorts script for a faceless channel on [niche].
Output: voiceover script + 8 visual b-roll cues + on-screen text every 5 seconds.
Voice tone: [tone].5. Channel-trailer short
Write a 40-second channel-trailer Shorts script. Channel is about [topic] for [audience].
Output: who-this-is-for hook (3s), what-you-get (15s), why-me (10s),
sub-CTA + 1 playlist link (12s).6. Long-form to Shorts repurpose
Below is a 10-minute long-form video transcript. Extract 3 short-form scripts (60s or less each).
Each must stand alone — no "as I mentioned in part 2". Mark which moments in the
long-form become which short.
[paste transcript]7. Listicle short
Write a 50-second "[N] [things] for [audience]" Shorts script.
Each item 8 seconds or less, with a clear transition cue ("number 3..."). End with a tease
for item [N+1] that lives on the long-form video.8. Reaction / reply short
I want to reply to [comment / video / claim]. Write a 35-second Shorts script.
Output: quote the claim, my actual position in 1 sentence, evidence in 20 seconds,
sub-CTA tied to a deeper long-form video.9. Mini-explainer of a complex topic
Explain [complex concept] in a 45-second Shorts script for a [beginner audience].
Use one analogy carried through the whole video. End with "if this clicked, my long-form
goes deeper". Mark visual cues.10. “Watch the full video” tease
I want this Short to drive views to my long-form on [topic]. Write a 30-second script
that delivers a real micro-payoff (1 useful thing) and earns the click for the long-form
by promising 3 more.11. Hook + on-screen text generator
For a Shorts script on "[topic]", generate the first 3 seconds: spoken hook +
first-frame on-screen text + visual cue at second 0. Give 6 variants.12. Retention-drop diagnoser
Below is my Shorts script and retention chart (paste timestamps + % retained).
Diagnose where the curve drops and propose script edits that hold retention longer.
Output: timestamp, current line, proposed line, why.
[paste]Common mistakes
- Hook 4+ seconds long — drop-off hits before the payoff curve starts.
- No second-loop reframe around the 8-second mark — viewers disengage mid-payoff.
- Sub-CTA before the viewer has gotten any value — “subscribe!” lands wrong.
- A Short that needs context from a long-form to make sense — every Short must stand alone.
- The same script template across very different topics — pacing should match the topic’s energy.
- End card baked into the final 2 seconds with no visual change — viewers swipe before the CTA loads.
FAQ
How long should a YouTube Short be in 2026? The hard limit is 3 minutes, but most data through June 2026 still points to 30-60 seconds as the best trade-off. Sub-25-second clips get the highest completion rate and account for the largest share of total views consumed; 50-60-second clips tend to pull the most raw views per clip (~76% average completion in published third-party studies). Match length to format using the table above.
Do views from these Shorts count toward monetization? Shorts ad revenue runs through the YouTube Partner Program. As of June 2026 the standard threshold is 1,000 subscribers plus either 10 million Shorts views in 90 days or 4,000 long-form watch hours; the lower fan-funding tier needs 500 subscribers plus 3 million Shorts views in 90 days or 3,000 watch hours. Watch time from Shorts does not count toward the 4,000-hour long-form requirement. Confirm current thresholds in YouTube’s monetization policies before relying on them.
Which AI model writes the best Shorts scripts? Any current flagship handles the timestamped structure: Claude Sonnet 4.6, GPT-5.5, and Gemini 3.1 Pro all stay on-format. Claude tends to keep the voice tighter; GPT-5.5 is strong at punchy hook variants (prompt #11). All three have free tiers that cover occasional scripting.
Why timestamp every beat instead of asking for “engaging”? The Shorts algorithm optimizes for retention percentage, and retention is won or lost at specific moments — the hook, the 8-second reframe, the payoff. Asking the model to write to named timestamps produces a script you can read against a timer and trim line by line, which a vague “make it engaging” never does.
Can I paste my retention chart and have it fix the script? Yes — that is prompt #12. Export the retention curve from YouTube Studio, paste the timestamps and percentages alongside your current script, and the model will flag the exact lines where the curve drops and propose tighter replacements.
