How to write a YouTube script that keeps retention (but or therefore)

You wrote the script, recorded the voice, cut the B-roll, and the retention graph still looks like a ski slope. People click, watch a minute, and leave somewhere in the middle. Nothing in the video is wrong exactly. It just never gives anyone a reason to stay for the next part.

That is almost always a script problem, and usually a small one. On r/NewTubers, one creator's post on fixing it got over 250 upvotes, and the fix was not a new hook formula or faster cuts. They changed the words between their points: every "and then" became "but" or "therefore". This guide turns that into a method you can run on any draft, including AI drafts for a faceless channel.

Two terms first. Retention is the share of viewers still watching at each moment of your video. A dip is a moment where many viewers leave or skip, and YouTube Studio marks dips for you.

What is the but or therefore method?

The but or therefore method is an editing pass: find every place where one point leads to the next, and make that link either a "but" (a problem, a twist, a contradiction) or a "therefore" (a consequence). If a link can only be "and then", the next point is either in the wrong place or should be cut.

The idea comes from the South Park creators, who described a story joined by "and then" as a list of events, and one joined by "but" and "therefore" as a story. A reply in that r/NewTubers thread pointed straight at it. A long r/Screenwriting answer put it simply: there is no conflict in "and" because it is expected, and conflict is what keeps people watching.

On YouTube, this matters more than in film, because the exit is one swipe away. Each "and then" is a natural stopping place. Each "but" opens a small question, and the viewer stays to hear it answered.

Why do "and then" scripts lose viewers?

Because an "and then" script gives the viewer the same amount of reason to leave at minute 2 as at minute 7. The points are true and maybe useful, but none of them depends on the next.

Compare the two shapes:

The faceless niches that suffer most are list videos, explainers and history summaries, because AI drafts and Wikipedia-style research both arrive as lists. That is exactly where this pass earns its keep. If you are still picking a niche, our guide to starting a faceless YouTube channel step by step covers which formats fit a beginner.

How to write a YouTube script that keeps retention, step by step

Write the draft fast, then run these six steps in order. The structure work happens in steps 3 and 4.

1. Write the payoff first. Decide the single thing the viewer will know or feel at the end. If you cannot say it in one sentence, the video is not ready.
2. Write the opening to match the title and thumbnail. Whatever the thumbnail promised, start delivering it in the first few seconds. No channel intro, no "before we begin".
3. List your beats on one page. One line per point, in order. A 10 minute script usually has 8 to 15 beats.
4. Connect every pair of beats with "but" or "therefore". Read down the list and write the connector between each pair. Where only "and then" fits, move the beat, merge it, or delete it.
5. Put the question in the transition. Before each new section, voice the question the viewer is about to have, then answer it. A reply in the r/NewTubers thread suggested exactly this, and it is the same move as "but" in a different costume.
6. Cut the ending to one payoff and one pointer. Deliver the last "therefore", then name one next video. Stop.

Tip: Do step 4 on the beat list, not the full script. It takes five minutes on a page of short lines and an hour on 1,500 words of prose.

The Faceless YouTube pack turns this into a pass you run on every AI-drafted script, alongside the opening template and the packaging rules that decide whether anyone clicks in the first place.

What does a but or therefore rewrite look like?

Here is a beat list from a typical history explainer, first as written, then rewritten. Same facts, different links.

Before (and then):

The ship left port in 1872.
And then the weather turned.
And then the crew were found missing.
And then theories spread about what happened.
And then most historians now favour one explanation.

After (but or therefore):

The ship left port in 1872 with a full crew and a safe cargo.
But a month later she was found drifting, with nobody aboard.
Therefore the first theory was the obvious one: pirates.
But nothing of value had been taken.
Therefore people reached for stranger answers, from sea monsters to mutiny.
But one detail in the logbook points somewhere far more ordinary.

The second version never lets the viewer close the loop until the end. Every line answers the last one and raises the next. One r/NewTubers reply called the same pattern set up, tension, payoff, and noted that a video can hold several of these loops, opening each gap and filling it right after.

Watch out: Not every "but" works. An r/Screenwriting reply warned that many buts are just "and then" with a different word. "The ship sailed, but the weather turned" is still a list if the weather never changes anything. The test is whether the next beat exists because of the turn.

How do you write the first 30 seconds?

Open on the promise of your title, not on yourself. YouTube's retention report has a specific metric for this: the intro figure shows what share of viewers are still watching after 30 seconds, and YouTube's own advice is to make sure those 30 seconds match what the title and thumbnail suggested.

A simple opening for a faceless video has three parts:

1. The promise, in one line (what the thumbnail showed).
2. The "but": why the obvious answer is wrong or incomplete.
3. The stakes: what the viewer gets by staying to the end.

One commenter in a r/NewTubers retention thread said the first 5 seconds need to deliver on the thumbnail, then around the one minute mark you add a "blind turn": something unexpected that is still on topic. That blind turn is just a well placed "but". A creator in r/PartneredYoutube who went from about 50 to over 80,000 views on one upload said they rewrote the intro several times and reworked the first 30 seconds before publishing. That is one story, not a guarantee, but it shows where the effort goes.

How long should a retention script be?

As long as the beats last and no longer. Most narrators read roughly 130 to 160 words a minute, so 1,000 words is about 6 to 8 minutes before edits. Write to the beats, then check the length, rather than padding toward a number.

Cutting is part of writing. One r/NewTubers creator said their raw recording is usually 20 minutes and the final video is 8. If you want the money side of length, including the 8 minute mid roll line, see the best video length for faceless YouTube.

How do you use AI to write a script without killing retention?

Use AI for the first draft and the research list, then do the structural pass yourself. Language models default to tidy lists with smooth "and then" transitions, which read well and watch badly.

A prompt that helps

Rewrite this outline as a list of beats for a [length] YouTube video.
Connect every beat to the next with "but" or "therefore", never "and then".
If a beat cannot connect that way, flag it instead of forcing it.
Open with the promise from this title: [title].

What to check by hand

• Does every "but" actually change what happens next?
• Is there any beat you would skip if you were watching?
• Are the facts yours, checked, and not lifted from another creator's video?

That last point matters. Threads in r/PartneredYoutube are full of creators complaining about channels that rewrite other people's scripts with AI, and other threads report AI-heavy channels losing monetization. Original research plus a tight structure is the safer and better product. Delivery matters too: the voice has to carry the pauses after each "but", which is why it is worth choosing carefully (our comparison of AI voices for faceless YouTube covers the options).

How do you check if your script kept retention?

Open YouTube Studio, go to the video's analytics, and look at the audience retention report on the Overview or Engagement tab. YouTube's help page explains that it marks dips (where viewers skip or leave), spikes (rewatches) and top moments, and the intro figure at 30 seconds.

Then work backwards to the script:

1. Note the timestamp of each dip.
2. Find the line in your script at that moment.
3. Ask what connector led into it. Most dips sit right after an "and then".
4. Write the fix into your next script, not just this one.

A few limits to know: YouTube says the data usually takes 1 to 2 days to process, and the key moments only show on videos at least 60 seconds long with at least 100 views. A reply in an older r/NewTubers retention thread put it well: generic tips often do not transfer, and your own graph is the most useful feedback you have.

What mistakes ruin script retention?

These come up again and again in r/NewTubers and r/PartneredYoutube threads:

• A slow start. Greetings, channel intros, or a "before we begin" add nothing the title promised.
• Tangents. One 100k creator wrote that every side plot not tied to the main topic is a liability, because viewers clicked for one thing.
• Long conclusions. Viewers leave the moment they sense the end. Recaps make that moment arrive early.
• Fake buts. A twist that changes nothing teaches viewers your twists do not matter.
• Fixing it in the edit. An editor in r/PartneredYoutube wrote that heavy zooms and constant motion graphics are wearing thin, and that pacing and story now do more. Editing can support a strong script, it rarely rescues a weak one.
• Never reading it aloud. Several creators say they read the script out loud and time it before recording. Clunky lines show up immediately.

Results vary by niche, topic and packaging. A better script will not save a video nobody clicks on, and nothing here guarantees views or income.

Where to go from here

Here is the plan for your next upload:

1. Write the payoff sentence and the opening that matches your title.
2. Reduce the draft to a beat list on one page.
3. Connect every pair with "but" or "therefore", and cut what will not connect.
4. Trim the ending to one payoff and one next video.
5. After two days, read the dips and carry the fixes into the next script.
