X algorithm
Also known as: Twitter algorithm, X algorithm 2026
The ranking system that decides which posts appear in the For You feed and in what order.
In depth
The X algorithm is a recommendation system that scores every candidate tweet against a viewer's likely engagement. Inputs include the viewer's past engagement patterns, the author's reputation, the post's recency, and signals from similar users.
X open-sourced parts of the algorithm in 2023, so the broad weighting is public knowledge: replies count for ~27×, reposts for ~20×, likes for ~30×, but engagement from accounts the viewer doesn't follow weights higher than engagement from existing followers.
AutoTweet's content recommendations are tuned against the published weights — favoring formats that historically generate higher reply-to-impression ratios.
