Methodology notes.

Prototype status. The current model is illustrative. A full methodology based on official platform data from Instagram, TikTok and YouTube is in development.

Inputs

Average per-post reach, likes, comments, shares and saves, normalised against reach rather than follower count.

Normalisation

Each component is mapped to 0–100 on a diminishing-returns curve, so outliers can't dominate a score.

Rankings

Top X% rankings are calculated within category and audience tier. In this prototype they are simulated.
