X/Twitter Algorithm Changes
Every major ranking change, policy update, and feature shift from January 2024 to today — and what each one means for your growth.
Current Engagement Weights
These weights determine how the algorithm scores each interaction on your posts. Higher weight means more algorithmic distribution.
| Action | Weight | What It Means |
|---|---|---|
| Reply + author re-engages | +75 | By far the highest value signal |
| Reply | +13.5 | Second strongest signal |
| Profile click + engagement | +12 | Shows deep interest in the author |
| Conversation click + engage | +11 | Thread engagement indicator |
| Dwell time 2+ min | +10 | Silent but powerful attention signal |
| Retweet | +1 | Lower than most people expect |
| Like | +0.5 | Baseline positive signal |
| "Not interested" click | -100x | Severe negative signal |
| Block / Mute | -1000x | Strongest negative signal |
Change Timeline
Grok-Powered Algorithm Open-Sourced
Entirely new recommendation algorithm built on xAI's Grok transformer architecture released on GitHub. End-to-end ML system replaces all hand-engineered ranking features.
Following Feed Goes Algorithmic
Grok AI now sorts the Following feed by predicted engagement instead of chronological order. Users default to For You feed on app open. Chronological view still accessible.
External Link Penalty Removed
X removed algorithmic penalties on posts with external links. Early data showed approximately 8x increase in link post reach and significant click-through rate improvements.
Updated Algorithm Documentation Published
X Engineering published updated ranking overview on GitHub confirming engagement weights. Reply where author re-engages: +75 weight. Like: +0.5. Offensive content: -80% reach.
Link Penalty Peaks at 50%
External link penalty reached its maximum: up to 50% reach reduction for single links, 70% for multiple links. Shortened URLs penalized an additional 10%.
Community Notes Affect Ranking
Tweets tagged with Community Notes receive 60-80% reach reduction and removal from For You recommendations. Accounts with multiple notes get overall authority reduction.
Thread Treatment Updated
Threads recognized as a single content unit. Thread completion rate became a ranking factor. Optimal length: 3-5 tweets for 70-80% completion.
Follower Quality Detection Launched
Algorithm now flags accounts with suspicious follower-to-view ratios. Suspected follower buying triggers 50-70% reach reduction and For You feed exclusion.
Video Content Priority Expanded
Video posts began receiving 2-4x more reach than text or image posts. Vertical format (9:16) and 15-60 second videos favored. 4 out of 5 sessions now include video.
External Link Penalties Increased
Posts with external links saw 20-30% reach reduction. Links to competitor platforms (Instagram, Facebook) penalized up to 60%.
Premium Subscriber Boost Solidified
X Premium subscribers confirmed to receive 2-4x more initial impressions. Premium replies prioritized in all threads regardless of engagement.
Key Takeaways for 2026
Replies are everything
A single reply where you engage back is worth 150x more than a like. Write content that prompts conversation and always respond to replies.
Premium matters
Premium subscribers get 2-4x initial reach advantage. Non-paying accounts need roughly 50% higher engagement to compete for equivalent placement.
Links are safe again
External link penalties were removed in October 2025. You can now share links without worrying about algorithmic suppression.
Grok runs the feed
The algorithm is now a Grok-based transformer that learns from behavior patterns. There are no more hand-coded rules to exploit — quality content wins.
