X Algorithm Mastery

Everything you need to know about the X (Twitter) algorithm. Based on X's open-source code, viral post analysis, and real engagement data.

TL;DR - The Golden Rules

1. First 2 hours are critical — replies/engagement in this window determine reach
2. No external links in main post — X penalizes links that take users off-platform
3. Media > Text — videos get 10x engagement, images get 2-3x
4. Reply to EVERYTHING — replies are weighted higher than likes/retweets
5. Post when audience is awake — 8 AM - 2 PM weekdays optimal
6. Controversy drives engagement — but pick battles wisely
7. Threads outperform single tweets — for long-form content

How the Algorithm Works

The 4-Step Process

1. Candidate Sourcing: Pulls ~1,500 tweets from accounts you follow (~50%) and similar accounts
2. Ranking: ML model scores likelihood you'll reply (highest), retweet, like, or report (negative)
3. Filtering: Removes blocked/muted, balances in/out-network, limits single author
4. Serving: Final mix with ads, 5B times/day, ~1.5 seconds

Engagement Weight Hierarchy

Ranking Signals

1. Recency

• Fresh content prioritized
• Peak visibility: first 2-3 hours

2. Engagement Velocity

• Speed matters more than total
• 100 likes in 30 min > 500 likes over 24 hours

3. Account Credibility

• Verified (Premium) gets boost
• Follower-to-following ratio matters
• History of bans/strikes hurts

4. Content Type

• Video: 10x engagement
• Images: 2-3x engagement
• Polls: Drives replies
• Threads: Higher total engagement

5. Link Presence

• Links = REACH PENALTY
• Put links in replies, not main post
• Quote tweeting a link > direct link

What Kills Your Reach

Instant Death

• ❌ External links in main post
• ❌ Getting reported/blocked

Slow Death

• ❌ Posting inconsistently

Posting Best Practices

Frequency

Timing (audience timezone)

• Best: 8 AM - 2 PM weekdays
• Good: 4 PM - 6 PM weekdays
• Worst: 11 PM - 7 AM

The No-Link Strategy

❌ Bad:  "Check out my article [link]"
✅ Good: "Here's what I learned (thread 🧵)"
         → Link in reply or final thread post

Getting Replies (Most Important)
