What makes a good niche?
High demand, low supply
Sustainable positive growth in real-time
Scalability and survivability
Let’s break those three qualities down in plain language.
Supply and demand
Supply: videos uploaded about a topic
Demand: viewers watching that topic
A video that attracts much more demand than its channel usually receives is an “outlier.”
Two formulas can help you estimate that demand:Video views - channel subscribers = volume
Subscriber count gives you a rough signal of the channel’s existing audience. Subtracting it from views helps reveal how many viewers may have come for the topic or idea itself.Video views / channel subscribers = outlier ratio
Outlier ratio is most useful for fresh videos. The longer a video has been public, the less reliable the score becomes.
An ideal example is less than a month old, has already reached the view range you care about (such as 100K), and has an outlier ratio above 1–2x. The useful threshold depends on the size of the channel.
Let’s look at some examples:
Example 1:
143.4K views - 15.6K subscribers = 127.8K volume
143.4K views / 15.6K subscribers = 9.2x outlier ratio
Ask yourself:
Is the demand coming from the topic or from the channel?
Sometimes an entire channel breaks out and all its videos perform unusually well. That can create a false positive. Look at several videos before drawing a conclusion. If the same topic breaks out across multiple channels, the signal is much stronger.
Example 2:
1. The “3I/Atlas trend” produced breakout videos across many channels. That suggests the topic itself was growing, rather than one channel simply having a strong run.
2. Many of the videos also showed excess demand and high volume. Most of these channels moved between 20K and 300K views, which is a healthy sign.
When smaller channels break out like this, it is another positive sign. Small channels often struggle when there is little demand in their niche.
But one important metric is still missing.
Volume and outlier ratio show excess demand, but they do not tell you whether that demand still exists. Viewers may already have moved on. That is why you also need a measure of current interest.
Current interest tells you how many people are watching a video or channel now.
Views per day (VPD) measures how many views a video or channel received over the past 24 hours. Combined with volume and outlier ratio, it gives you a clearer picture of what is working now. Fresher data usually produces a more reliable signal.
Example:
These channels currently receive between 34,000 and 206,000 views per day. That points to strong demand in the niche. If several channels each have multiple videos receiving at least 5K–10K views per day, current interest is likely high. That can be a good sign that the niche is worth exploring.
Keep in mind: useful thresholds vary between niches, so treat this as a rule of thumb rather than a guarantee.
Scalability and survivability
Every YouTube niche behaves like a market, and markets move through different phases. Some niches last for decades, while others disappear within weeks. Some attract millions of views, while others top out at a few thousand. Decide whether your strategy is short term or long term before you commit. Start by asking whether the niche is driven by news, a new technology, or something with a long history.
News-related niches are short-lived and volatile, but can have high potential (for example, a presidential election).
New technology may produce a short-lived trend or develop into a lasting niche (for example, AI software).
Established fandoms tend to be longer-lived and less volatile, with slower but more consistent growth (for example, Marvel).
Is it in line with what you want to enter (short-term, long-term)?
If it is long-lived, can you create 50 or more exceptional videos?
If it is short-lived, is there enough demand? Use the metrics discussed above.
If it is long-lived, is the market large enough? Look at the biggest videos in the niche and compare their view counts with your goals.
How to stand out
Validating demand is only one part of choosing a niche. You also need to offer viewers something meaningfully different. Do not copy another creator outright. Find a way to add value of your own:
Offer a unique angle: cover a familiar topic from a different perspective.
Change the format: if every competing video is 20 minutes long, try a thoughtful one-hour version.
Transfer a pattern: take a format that works elsewhere and adapt it to your channel blueprint.
Raise the production bar: invest the time and resources to make a genuinely better video (advanced).
How to stand out: use a unique angle
Cover a high-demand topic in a different way. For example, keep the topic of Tokyo capsule hotels but approach it from a perspective viewers have not seen.
How to stand out: change the format
If everyone creates two-hour documentaries, consider delivering the same kind of value in 15 minutes. A different length can work well when a niche has become saturated with one format.
How to stand out: transfer a pattern
Find a successful format in another niche, understand why it works, and adapt the underlying structure to your subject and audience.
Checklist
Is there demand for the same topic or format across multiple channels?
Do you have confirmed demand across all metrics? (volume, outlier ratio and views per day, all at the same time?)
Are small channels breaking out in the niche?
Does the niche match your ambition, and can you produce enough high-quality videos? Consider longevity, virality, and market size.
Do you offer something new to the market or provide something that is 10x better than the competition?
How can you find niches faster?
Use a niche finder to bring breakout videos and promising niches into one place. Mittalmar includes the metrics you need to evaluate them, including outlier ratio, volume, and views per day.
