Scoring & rank
Amplification rate
Shares and sends per reach — how often viewers pass content onward — the metric that captures distribution beyond the original audience.
How INFLU measures it
Tracked as a per-post ratio; high amplification is the strongest single predictor of a post escaping the creator’s follower base.

Share rate
Sends per reach — the normalised form of shares that lets a 50K-follower post compete with a 5M-follower one.
Viral score
A per-post score measuring how far a piece of content outperformed the creator’s own recent baseline — not raw views, but performance adjusted for audience size.
