How INFLU measures it

Share rate
Sends per reach — the normalised form of shares that lets a 50K-follower post compete with a 5M-follower one.
Amplification rate
Shares and sends per reach — how often viewers pass content onward — the metric that captures distribution beyond the original audience.
Saves
Bookmark taps on a post — for fashion, the strongest intent signal available, because people save outfits they plan to copy or buy.
