Which niche should I pick, and how do I write a good script?

Short answer

There is no single best niche. A good niche passes three checks: small channels are getting big views in it right now, it earns enough per view for your goal, and you can make 50 videos in it without running out of ideas. A good script is a chain of small promises, each one kept before the next is made.

The three niche checks

1. Small channels win there. Search the topic in OutlierKit. If channels with under 20,000 subscribers are getting 5 to 20 times their normal views, the topic is open. Strangers are clicking on videos from channels they have never heard of, which is exactly your situation on day one. If only huge channels appear, the topic is owned.
2. It earns enough. Finance, business, and education pay more per view than entertainment. Decide what you need before you choose. A niche that passes the first check but pays a fraction of what you need is a hobby, and that is fine, as long as you chose it knowing. The niches guide has the per-niche earnings picture, and the RPM benchmarks collect every published range.
3. You can make 50 videos. Write down 20 video ideas now. If you cannot, the niche is too narrow for you. A channel needs a year of weekly videos to find its shape, and a niche that runs dry at video twelve will not get you there.

Geography is the worked example on this page and passes all three checks. Three geography channels of very different sizes were overperforming on 4 September 2026, from 1,200 to 19,000 subscribers, which is the first check passed; the starting-a-channel post shows all three. Education-style facts content earns at the middle of the range. And "N facts about [place]" can be made by country, by continent, or by theme for years.

The video the script shape comes from

Price of Travel has 19,000 subscribers. This video got 496,000 views, 22.9 times the channel's normal. It is faceless for most of its length and plainly edited. What it has is a script that makes a small promise every 20 to 30 seconds and keeps every one of them. The timeline below is that script's shape.

Check one, across four channel sizes

Here is the first check passing in geography, with the video above and three more from the index pulled on 4 and 7 September 2026.

Curios Earth, with 1,200 subscribers, got 6,800 views, 5.7 times its normal. Maply, with 5,720 subscribers, got 113,000 views, 86.9 times normal. Borderline Wonders, with 15,400 subscribers, got 347,000 views, 26.7 times normal. With Price of Travel at 19,000 subscribers and 22.9 times, that is four channels under 20,000 subscribers all beating their normal by more than five times. The topic is open.

The script shape, taken from the 22.9x video

In words: the first 15 seconds is the hook, one fact that proves the title is true, told as something that surprised the creator. Seconds 15 to 25 say why it matters: my mental map was wrong, and yours probably is too. Seconds 25 to 30 say what is coming by repeating the number from the title. The main part gives every item the same two-beat shape, what you would assume and then what is actually true, 20 to 30 seconds each, with the biggest surprise about two thirds of the way through. The ending points to the next video in the series and does not say goodbye for a minute.

Before you write your own, read the transcripts of the top three videos in your niche in OutlierKit and mark where each one makes and keeps a promise. Your script should follow the same rhythm. The hooks and retention post covers the first 30 seconds in more depth, the script writing guide has templates for other formats, and the free script template gives you the beats as a fill-in document.

Why the niche and the script are one decision

The niche check tells you whether strangers are clicking on videos in that topic. The script shape tells you whether those strangers stay once they click. Pass the first and fail the second and you get impressions with no watch time, which YouTube stops rewarding after a few videos. Pass the second and fail the first and you have a beautiful script nobody is shown. The 22.9x video passed both, which is why a 19,000-subscriber channel reached half a million people.

If you have a niche already and want to know what is moving inside it, the post on finding trends in your niche picks up from here. If you are comparing several candidate niches, the prompt at the end of this page checks three at once and then drafts a script outline from the best one's transcript. There is also a longer discussion of how to find your YouTube niche on the blog.

Words used on this page

Niche

The topic and audience a channel serves. Narrow enough that one viewer wants every video, wide enough for 50 of them.

RPM

Revenue per thousand views, after YouTube's share. The number that makes finance pay more than entertainment.

Open loop

A promise made and not yet kept. A script is a chain of them, each closed before the next opens.

Outlier multiplier

A video's views divided by what its channel usually gets. 22.9x means the video did 22.9 times the channel's normal.
