Keyword Performance Score

// Calculate Keyword Performance Index (KPI)
function calculateKPI(keywordData) {
  const {
    position,
    searchVolume,
    cpc,
    difficulty,
    clicks,
    conversions
  } = keywordData;
  
  // Weighted scoring (adjust weights based on goals)
  const positionScore = position <= 3 ? 100 : 
                       position <= 10 ? 80 : 
                       position <= 20 ? 60 : 
                       position <= 50 ? 40 : 20;
  
  const volumeScore = Math.min(searchVolume / 1000 * 100, 100);
  const commercialScore = cpc > 5 ? 100 : cpc > 2 ? 80 : 60;
  const difficultyScore = 100 - difficulty;
  const conversionScore = conversions > 0 ? 100 : 
                         clicks > 10 ? 60 : 30;
  
  // Weighted average
  const kpi = (
    positionScore * 0.3 +
    volumeScore * 0.2 +
    commercialScore * 0.2 +
    difficultyScore * 0.1 +
    conversionScore * 0.2
  );
  
  return Math.round(kpi);
}

// Usage example
const keyword = {
  position: 5,
  searchVolume: 2400,
  cpc: 3.50,
  difficulty: 45,
  clicks: 150,
  conversions: 8
};

const kpiScore = calculateKPI(keyword); // Returns score 0-100
