# How to Go Viral Per X's Algorithm Source

> Actionable ranking factors and reach mechanics based on open-sourced X code

A breakdown of content distribution and reach mechanics extracted directly from X's open-sourced recommendation algorithm codebase. It details the mathematical and structural signals that amplify tweets, such as account reputation thresholds, media inclusion, and multi-format engagement. It is a practical reference for anyone trying to optimize post distribution based on actual system rules rather than speculation.

## How it works

Build reputation — tweets below MIN\_USER\_REPUTATION (40.0) get the lowest retweet-based score. Content that helps: URLs/links, media/video, trending topics, verified account boosts. What hurts: offensive/flagged content, spam/bot penalties, being a reply. Practical takeaways: 1. Craft retweetable content (shareability over likes). 2. Engage quickly — early momentum beats time decay. 3. Multi-format engagement — replies AND quotes AND retweets. 4. Add media & links. 5. Build account reputation over time. 6. Tap into trends. 7. Be authentic — avoid spam/low-quality flags. The algorithm tracks "viral content creators" (ViralContentCreatorMetricsFeatureHydrator.scala), so consistent viral performance amplifies future reach.

## What it is for

- Optimize tweet formatting with media and links to trigger positive ranking weights
- Time post interactions to establish early engagement momentum against decay penalties
- Audit an account's publishing behavior to avoid reputation drops and spam flags

## Key points

- Account reputation baseline: Avoid dropping below MIN\_USER\_REPUTATION (40.0) to maintain normal retweet distribution scoring
- Heavy weighting on shareability: Algorithm favors retweets and quotes over passive likes
- Early engagement velocity: Initial interaction speed outweighs standard recency time decay
- Rich media preference: Posts containing images, video, and outbound links receive distribution boosts
- Viral creator tracking: Demonstrates how system features reward creators who consistently generate viral reach
- Penalty avoidance: Downranking factors include spam flags, offensive categorization, and standalone reply status
