Outlier score: how the multiplier works

The outlier score, or multiplier, tells you how many times more views a video got than its own channel usually gets. A 5x video got five times the channel's normal views, which makes it worth studying.

Who it is for

Creators looking for video ideas that already beat a channel's normal views
Faceless channel owners studying which topics small channels win with
Anyone checking if a viral looking video is really unusual for its channel
Researchers comparing videos from channels of very different sizes

Use something else when

Predicting how many views your own video will get
Judging a channel with fewer than 5 scored uploads, since it gets no multiplier
Measuring revenue or earnings, which is a separate estimate

How to use it

Open Outliers and type a topic, or pick a preset such as Hidden gems.
Choose Long-form or Shorts so you compare like with like.
Sort by multiplier and set a minimum, for example 5x, to see strong breakouts only.
Click a card and read the baseline count, confidence and observation date next to the multiplier.
Open the video page to see the exact sum: views divided by the baseline.
Save the idea or send it to your Board, then make your own original version.

What the multiplier means

Every channel has a normal level of views. A small channel might get 2,000 views on a usual video. A big one might get 500,000. Raw views alone cannot tell you which video did unusually well.

The multiplier fixes this. It compares a video with its own channel's usual views. If a video has 100,000 views and the channel's baseline is 20,000 views, the multiplier is 5x. That video did five times better than normal for that channel.

This is why a 40,000 view video on a small channel can be a bigger signal than a 1,000,000 view video on a giant channel. The small channel's audience did not carry it. Something about the topic, title or thumbnail did.

The multiplier is a TubeMind estimate computed from public YouTube view counts. It is not a YouTube metric and YouTube does not show it.

How the number is calculated

The formula is simple: views divided by the channel's baseline. The care goes into building the baseline.

Median, not average. The baseline is the median views of the channel's last 30 uploads. A median ignores one or two huge hits, so they do not lift the baseline.
Same format only. Shorts are compared with Shorts. Long videos are compared with long videos.
Similar length. A long video is compared with uploads from half to double its own length, when at least 5 such uploads exist. So a 40 minute episode is not divided by the views of 2 minute clips. With fewer than 5 matches, all same format uploads are used.
Settled videos only. Uploads younger than 7 days are left out, because their views are still climbing. They are only used when fewer than 5 older uploads exist.
The video itself is excluded from its own baseline.
At least 5 uploads. Without 5 comparable uploads, there is no multiplier.
A floor of 1,000 views. For the sum, the baseline never goes below 1,000 views. This stops silly ratios on almost dead channels. Example: a video with 8,000 views on a channel whose median is 400 shows 8x, not 20x.

TubeMind also shows a z-score (how far above the channel's own average the video sits, over its last 100 comparable uploads) and views per hour since publishing.

How to read it

Multiplier	Label	What it suggests
Under 2x	Normal	Around what this channel usually gets. Not a signal on its own.
2x or more	Good	A solid above average video. Note the angle.
5x or more	Strong	Clearly beat the channel's norm. Study the title and thumbnail closely.
10x or more	Viral	A true outlier for that channel. Check it is repeatable before you copy the idea.

Read the table from top to bottom. A 3x video is good, a 7x video is strong, and a 15x video is viral for that channel. Remember that 5x means five times the usual views, not five times growth.

You see the multiplier on the Outliers screen, on each video page with the full sum, in the uploads list on channel pages, and in the Chrome extension right on YouTube.

Outlier Confidence: when to trust a big number

Next to the multiplier you see a confidence level: high, medium or low. It starts at 100 and loses points for each warning sign:

The baseline has fewer than 10 videos (a big cut) or fewer than 20 videos (a small cut).
The video has a declared paid promotion, so some reach was bought.
The multiplier is 50x or more, which often comes from ads or a baseline glitch. 20x or more gets a smaller cut.
The median based multiplier is far above the average based one, a sign the channel mixes formats such as clips and full episodes.
The video is less than 48 hours old, so the number is still moving.
Views far exceed the subscriber count, which can mean outside traffic.

A score of 75 or more is high, 45 or more is medium, and anything lower is low. Hover the badge to read the exact reasons.

Limits and caveats

A multiplier shows that a video did well. It does not prove that the topic, title or thumbnail caused it.
YouTube's API does not mark Shorts. TubeMind treats a video of 3 minutes or less (60 seconds or less before 15 October 2024) as a Short, so a normal 2 minute video can be counted as one.
Live streams are left out of outlier lists.
Lists stop at 1,000x, because above that the number is rarely real.
Views change over time. Always check the observation date.
How many outliers you see per search depends on your plan. See Plans and limits.

Questions

What is a good outlier score on YouTube?

In TubeMind, 2x is good, 5x is strong and 10x or more is viral for that channel. A 5x video on a small channel with a high confidence level is usually the most useful idea to study.

Why does a video with fewer views have a higher multiplier?

Because the multiplier compares each video with its own channel. 50,000 views on a channel that normally gets 5,000 is 10x. 500,000 views on a channel that normally gets 400,000 is close to 1x.

Why are Shorts and long videos scored separately?

Shorts and long videos get very different view counts on the same channel. Mixing them would make long videos look weak or Shorts look strong. So each video is only compared with uploads of the same format.

Why does a video have no multiplier?

The channel needs at least 5 comparable uploads of the same format. Below that, the baseline is too thin, so TubeMind shows no multiplier instead of a guess.

Is the outlier score YouTube data?

No. It is a TubeMind estimate built from public view counts. YouTube does not publish it, and it is not a promise that a similar video will get similar views.

Why does the sum on the video page not match exactly?

The baseline has a floor of 1,000 views for the ratio, and views keep changing after the score is stored. When the numbers do not reproduce the same value, the video page says so.
