what does this score measure?
In X's ranking code, open-sourced in January 2026, replies, quotes and conversation chains outweigh likes by a wide margin. That's what this measures: does your tweet invite replies, quotes and bookmarks — or does it fall into patterns that get reach penalties. No AI involved: fixed, auditable rules.
