The outlier score is the number on every video in vidfora. It's the single most important concept in the product.
The definition
Outlier score = a video's views ÷ the median views of its own channel's mature videos in the same format.
A 10x score means the video did ten times what that channel typically does. A 1x score means it performed exactly like a normal upload from that channel. Below 1x, it underperformed.
Why "median", and why "same format"
Median, not average. One monster hit drags an average upward and makes every other video on the channel look like a failure. The median — the middle video — describes what the channel actually does on a normal week, so the baseline is honest.
Same format. Shorts and longform videos live in completely different view-count universes on YouTube. Scoring a Short against a channel's longform median would mark almost every Short as a runaway hit. So longform is scored against longform, Shorts against Shorts.
Mature videos. A video uploaded three hours ago hasn't finished accumulating views. Including it in the baseline would drag the median down and inflate everything else's score.
Why this beats sorting by views
Sorting by raw views is a popularity contest that big channels always win. You end up studying what large channels do, which mostly tells you what happens when a large audience is already subscribed.
Scoring against a channel's own baseline neutralises audience size. A 200K-view breakout from a 15K-subscriber channel scores far higher than a 3M-view coast from a channel with 10M subs — because the small channel's video was carried by the idea, not the audience. Those are the ideas worth reverse-engineering.
How to read the numbers
| Score | What it means |
|---|---|
| 2x–4x | Solid overperformance. Worth noting. |
| 5x–9x | A real breakout. The packaging or the angle did something. |
| 10x–19x | Strong signal. Study this one properly. |
| 20x+ | Exceptional. Often a topic that found an audience the channel didn't know it had. |
Roughly one upload in ten clearly beats its channel's baseline. Filtering to 5x and above is a good default for finding ideas without drowning in noise.
One caveat worth knowing
A very small channel with an inconsistent history can produce a dramatic multiplier from a modest video — if a channel's median is 800 views, a 40K video scores 50x. That's a genuine signal, but check the absolute view count too before you build a content plan on it. The feed lets you filter on both.
