Core Components

• Data Collection
  Extracted via platform APIs or web scraping and includes metrics such as likes, comments, shares, impressions, follower activity, audience demographics, and content metadata.
  
  
• Performance Metrics & KPIs
  Used to measure engagement and content efficiency. Common formulas include:
  
  
• Engagement Rate:

(Likes + Comments + Shares) / Impressions

‍

• CTR (Click-Through Rate):‍

(Clicks / Impressions) × 100

‍

• Follower Growth Rate:
  Evaluates audience expansion over time.
  
  
• Sentiment Analysis
  Uses NLP to classify opinions as positive, neutral, or negative.
  Average sentiment:

 Sentiment Score = Σ sentiment(i) / n

‍

• Trend & Topic Analysis
  Identifies viral themes, hashtags, and conversation patterns to track shifts in audience interest and content demand.
  ‍
• Network Analysis
  Applies graph theory to map relationships between users, identifying influencers, communication flow paths, and community structures.

  Examples:
  ‍
  • Degree Centrality
    
  • Betweenness Centrality:
    

BC = Σ(σst(v) / σst)

‍

Mathematical Representation

• ‍Engagement Rate:

ER = (Σ interactions / impressions) × 100

‍

• Moving Average (Trend Tracking):
  

MA = (1 / t) × Σ engagement(i) over t

‍

• Topic Modeling:
  Often performed using Latent Dirichlet Allocation (LDA) to classify text into themes.
