🔍 Algorithm Analysis

+
+

Why These Rankings Make Sense:

+
    +
  • Wikipedia (Rank #1): High authority domain + many clicks + exact title match
    • +
  • Complete Guide (Rank #2): Excellent content relevance + good click volume + comprehensive title
    • +
  • GitHub (Rank #3): Very high authority + fresh content + technical relevance
    • +
  • StackOverflow (Rank #4): High authority + good clicks + exact keyword match
    • +
  • Medium Article (Rank #5): Fresh content + good authority, but less specific to query
    • +
+ +

🎯 Key Algorithm Features Demonstrated:

+
    +
  • Authority Recognition: Wikipedia and GitHub get authority boosts
    • +
  • Content Matching: Titles with exact matches rank higher
    • +
  • User Behavior: Pages with more clicks get ranking boosts
    • +
  • Freshness Factor: Recent content gets appropriate scoring
    • +
  • Quality Assessment: Complete metadata and good structure matter
    • +
