X Impact Checker

Analyze X posts for viral potential and optimize them using the open-source recommendation algorithm — both a 19-element scoring system and deep algorithm architecture understanding.

When to Use

• Score a tweet draft before publishing
• Understand why a tweet underperformed
• Rewrite tweets to align with Twitter's ranking mechanisms
• Build topical authority in a specific niche
• Debug inconsistent engagement rates

Algorithm Architecture

Understanding the underlying models helps explain why the scoring works.

Core Ranking Models

Real-graph — Predicts interaction likelihood between users

• Determines if your followers will engage with your content
• Strategy: Make content your specific follower segment will engage with

SimClusters — Community detection with sparse embeddings

• Identifies communities with similar interests; your tweet resonates within these clusters
• Strategy: Pick ONE clear topic and serve tight communities deeply

TwHIN — Knowledge graph embeddings mapping users and content topics

• Helps Twitter understand if your tweet fits your established identity
• Strategy: Stay in your niche or clearly signal topic shifts

Tweepcred — User reputation/authority scoring

• Your past engagement history affects current tweet reach
• Strategy: Build through consistent quality, not engagement bait

Engagement Signals

Explicit (high weight): Likes, replies, retweets, quote tweets

Implicit (also weighted): Profile visits, link clicks, dwell time, saves/bookmarks

Negative: Block/report (heavily penalized), mute/unfollow, quick scroll-past

Optimization by Algorithm Layer

Layer	Strategy
Real-graph	Ask questions; create debate; post when followers are active
SimClusters	One clear topic; use community language; provide niche value
TwHIN	Lead with domain expertise; stay consistent; build topical authority
Tweepcred	Reply to quality accounts; avoid engagement bait; engage deeply

Detailed Scoring Criteria

Reply Potential (22 pts)

• Direct questions, debatable claims, opinion invitations
• ❌ "Just shipped a new feature." → ✅ "Should features ship fast but buggy, or slow but stable? We chose speed—was it the right call?"

Retweet Potential (16 pts)

• Actionable insights, surprising facts, numbered lists, data-driven content
• ❌ "I learned something today." → ✅ "🧵 3 React patterns that cut my bundle size by 30%: 1. Lazy loading hooks 2. Code splitting by route 3. Tree-shaking unused exports"

Favorite Potential (12 pts)

• Emotional resonance, personal stories, relatable moments, vulnerability
• ❌ "Debugging is hard." → ✅ "Spent 3 hours debugging a production issue. The fix? A missing semicolon I added during 'quick cleanup' at 2am. Never touching working code past midnight again 😅"

Quote Potential (10 pts)

• Strong opinions, challenges conventional wisdom, clear stances
• ❌ "TypeScript is useful." → ✅ "TypeScript's biggest value isn't catching bugs—it's documentation. The type errors are just a bonus. Fight me."

Dwell Time (6 pts)

• Long-form content requiring reading time; detailed explanations; technical depth

Continuous Dwell Time (4 pts)

• Thread indicators (🧵, "1/"), narrative structure, complexity requiring re-reading
• ❌ "Here's how I built X." → ✅ "🧵 How I went from idea to $10k MRR in 30 days (1/8)\n\nDay 1-7: Validation..."

Profile Click (5 pts)

• Creates author curiosity; demonstrates expertise; credibility signals
• ❌ "I think React is good." → ✅ "After architecting React apps for Airbnb, Netflix, and 50+ startups, here's what I wish I knew on day one:"

Follow Potential (4 pts)

• Demonstrates ongoing value; establishes content cadence
• ❌ "Here's a React tip." → ✅ "React tip #47: [insight]\n\nI break down advanced React patterns every Monday."

---

Score Normalization

Final Score = Base Score (0-100) + Penalties (-75 to 0)
Normalized Score = max(0, min(100, Final Score))

Penalty capping: total penalties > -20 causes gradual dampening; hard cap at -75.

Text Analysis Limitations

This skill performs heuristic text-based analysis, not ML prediction. It cannot detect actual media presence, real engagement metrics, author follower count, or network graph relationships. Best used for pre-publishing optimization, not post-hoc analytics.

Language Handling

Detect input language. Respond in same language. Keep optimized version in original language.

When input is in Japanese, display Category and Factor names as: 日本語訳（English Original）
