A channel can have a million subscribers and a median video a few thousand people watch. Another has fifty thousand who turn up every time. A follower count cannot tell them apart. The IFX Score can.
Three pillars, sixteen parts
Impact (35%): how strongly the content lands. Depth of reaction (likes plus five times the comments, per view), conversation (comments per 1,000 views) staying power (videos older than ten days still gaining views) and the best upload against audience size.
Followership (35%): the audience behind the creator. Size, loyalty (a mature upload’s median views as a share of subscribers), growth once three days of history exist, live turnout (peak viewers at the creator’s own live streams, against subscribers) for those who go live, and reaching beyond subscribers (how many uploads are watched by more people than follow the creator).
eXposure (30%): how far and how often they are seen. Reach per upload, regular publishing, steady results, hit rate (how often an upload reaches the typical peer upload), fresh uploads (how recently they published), momentum (are newer uploads doing better than older ones) and the early pull of new uploads.
For smaller creators. Four of the sixteen parts (best upload against audience size, reaching beyond subscribers, momentum and early pull) do not depend on how many followers a creator already has. They reward content that travels and improves, so a small creator can score well.
Ranked against peers
Each part is ranked within the comparison, not on a fixed scale. A part that cannot be measured is left out and the rest re-weighted.
Confidence, built in
Every score carries a confidence from uploads, subscriber data and days of history. Missing evidence pulls the shown score toward 50, so three uploads cannot earn a confident 90. Low-confidence scores are tagged preliminary.
A score that is never unsure is not measuring anything.
A profile in plain words
Steady, Rising, Hit-driven, or Impact-led, Follower-led, Exposure-led, Balanced. It also names the better format, Shorts or full videos, when both can be compared.
What it does not measure
Saves, shares and conversions are not public. Other platforms are not seen; the score is YouTube only for now. An open high-risk radar flag takes 10 points; a confirmed one withholds the score.
The rule
Use the score to decide where to look. Then read the three bars.
