X's Recommendation Weights Decoded: a Link Copy Is Worth 30 Likes, a Report -355

FinanceYF5 · x · 2026-10-27

Positive interaction weights (relative to 1 like): copy link 30x, reply between mutuals 30x, reply/quote/DM share 7.6x, follow-from-tweet 6x, retweet 1.5x, like 1x, bookmark 0.
Negative actions weigh more: report -355x, mute -89x, "not interested" -79x, block -47x. Reports are so heavily weighted because they occur 1,000x less often than likes; predicted report/mute risk demotes a tweet early.
Distribution mechanics: accounts under 50k followers get one new-post boost to roughly position 16 in the feed, lasting only the first 2 hours and stopping after 200 Home feed impressions; the system boosts one post per load and favors early like-rate.
Reach rules: replies/retweets only reach followers; original tweets reach non-followers at a 25% score penalty; competing posts from the same account keep 62.5% (2nd) and 43.75% (3rd) of the score; recommendation effectively ends after 48 hours.
Key detail: interactions only count when discovered in-feed—clicks from group-chat links don't help, and low-quality-flagged content can't be interacted with at all. The algorithm rewards whether the first readers carry your content to others, not posting volume.
