                                               bids      winner(s)

Auction Types

First-Price Auction:

• Winner pays their bid amount
• Simple implementation
• Buyers bid conservatively
• Lower revenue potential

Second-Price Auction:

• Winner pays second-highest bid + $0.01
• Encourages true value bidding
• Higher revenue potential
• More complex logic

Reserve Price Auction:

• Minimum acceptable bid
• Protects seller revenue
• May reduce fill rate
• Quality threshold

💰 Advanced Pricing Strategies

Dynamic Floor Pricing

Adjust minimums based on conditions:

function calculateFloorPrice(lead) {
  let baseFloor = 15.00;
  
  // Time-based adjustment
  const hour = new Date().getHours();
  const timeMultiplier = (hour >= 9 && hour <= 17) ? 1.2 : 0.9;
  
  // Quality adjustment
  const qualityScore = calculateQualityScore(lead);
  const qualityMultiplier = 0.5 + (qualityScore / 100);
  
  // State premium
  const statePremiums = {
    'CA': 1.3,
    'TX': 1.2,
    'FL': 1.15,
    'DEFAULT': 1.0
  };
  const stateMultiplier = statePremiums[lead.state] || statePremiums.DEFAULT;
  
  // Calculate final floor
  return baseFloor * timeMultiplier * qualityMultiplier * stateMultiplier;
}

Bid Shading

Reduce winning bid strategically:

function shadeBid(winningBid, secondBid, bidHistory) {
  // Calculate historical win rate
  const historicalWinRate = bidHistory.wins / bidHistory.total;
  
  // More aggressive shading if high win rate
  let shadePercent = historicalWinRate > 0.7 ? 0.95 : 0.98;
  
  // Never shade below second price + increment
  const minimumPrice = secondBid + 0.50;
  const shadedPrice = winningBid * shadePercent;
  
  return Math.max(shadedPrice, minimumPrice);
}

Bundle Pricing

Offer volume discounts:

function calculateBundlePrice(buyer, lead, dailyVolume) {
  const tiers = [
    { volume: 1000, discount: 0.95 },
    { volume: 500, discount: 0.97 },
    { volume: 100, discount: 0.99 },
    { volume: 0, discount: 1.0 }
  ];
  
  const tier = tiers.find(t => dailyVolume >= t.volume);
  const basePrice = calculateBasePrice(lead);
  
  return basePrice * tier.discount;
}

📊 Quality Score Integration

Multi-Factor Scoring

Comprehensive quality assessment:

function calculateQualityScore(lead) {
  const weights = {
    dataCompleteness: 0.2,
    phoneQuality: 0.2,
    emailQuality: 0.15,
    consentRecency: 0.15,
    sourceReputation: 0.15,
    demographicMatch: 0.15
  };
  
  const scores = {
    dataCompleteness: scoreDataCompleteness(lead),
    phoneQuality: scorePhoneQuality(lead),
    emailQuality: scoreEmailQuality(lead),
    consentRecency: scoreConsentAge(lead),
    sourceReputation: getSourceScore(lead.source),
    demographicMatch: scoreDemographics(lead)
  };
  
  return Object.entries(weights).reduce((total, [factor, weight]) => {
    return total + (scores[factor] * weight);
  }, 0);
}

Quality-Based Routing

Route by quality tiers:

function routeByQuality(lead, buyers) {
  const qualityScore = lead.qualityScore;
  
  if (qualityScore >= 90) {
    // Premium buyers only
    return buyers.filter(b => b.tier === 'premium');
  } else if (qualityScore >= 70) {
    // Standard buyers
    return buyers.filter(b => ['premium', 'standard'].includes(b.tier));
  } else if (qualityScore >= 50) {
    // All buyers except premium-only
    return buyers.filter(b => !b.premiumOnly);
  } else {
    // Remediation flow
    return buyers.filter(b => b.acceptsLowQuality);
  }
}

🎯 Bid Optimization Algorithms

Machine Learning Prediction

Predict optimal pricing:

class BidPredictor {
  constructor(historicalData) {
    this.model = this.trainModel(historicalData);
  }
  
  predictOptimalPrice(lead, marketConditions) {
    const features = {
      // Lead characteristics
      state: oneHotEncode(lead.state),
      age: normalize(lead.age),
      creditScore: normalize(lead.creditScore),
      
      // Market conditions
      hourOfDay: cyclicalEncode(marketConditions.hour),
      dayOfWeek: oneHotEncode(marketConditions.day),
      competitorCount: marketConditions.activeBuyers,
      
      // Historical performance
      sourceConversionRate: this.getSourceMetrics(lead.source),
      categoryDemand: this.getCategoryDemand(lead.category)
    };
    
    return this.model.predict(features);
  }
}

Reinforcement Learning

Continuously improve pricing:

class PricingAgent {
  constructor() {
    this.qTable = {};
    this.learningRate = 0.1;
    this.discountFactor = 0.95;
    this.explorationRate = 0.1;
  }
  
  selectAction(state) {
    // Epsilon-greedy strategy
    if (Math.random() < this.explorationRate) {
      return this.exploreNewPrice(state);
    } else {
      return this.exploitBestPrice(state);
    }
  }
  
  updatePolicy(state, action, reward, nextState) {
    const currentQ = this.getQ(state, action);
    const maxNextQ = this.getMaxQ(nextState);
    
    // Q-learning update rule
    const newQ = currentQ + this.learningRate * 
      (reward + this.discountFactor * maxNextQ - currentQ);
      
    this.setQ(state, action, newQ);
  }
}

🔄 Market Dynamics

Supply and Demand Balancing

Adjust for market conditions:

function adjustForMarketConditions(basePrice, metrics) {
  const supplyDemandRatio = metrics.activeLeads / metrics.activeBuyers;
  
  // High supply, low demand = lower prices
  if (supplyDemandRatio > 2) {
    return basePrice * 0.85;
  }
  // Balanced market
  else if (supplyDemandRatio > 0.5) {
    return basePrice;
  }
  // Low supply, high demand = higher prices
  else {
    return basePrice * 1.25;
  }
}

Competitive Response

React to competitor behavior:

function respondToCompetition(ownBid, competitorBids, strategy) {
  const avgCompetitorBid = average(competitorBids);
  const maxCompetitorBid = Math.max(...competitorBids);
  
  switch(strategy) {
    case 'aggressive':
      // Always try to win
      return maxCompetitorBid + 1.00;
      
    case 'value':
      // Maintain margins
      return Math.min(ownBid, avgCompetitorBid * 1.1);
      
    case 'selective':
      // Only compete for quality
      if (lead.qualityScore > 85) {
        return maxCompetitorBid + 0.50;
      } else {
        return ownBid * 0.9;
      }
  }
}

⚡ Performance Optimization

Auction Speed

Minimize latency:

class FastAuction {
  constructor() {
    this.bidTimeout = 100; // 100ms max
    this.connectionPool = new ConnectionPool(20);
  }
  
  async collectBids(bidRequests) {
    // Parallel bid collection with timeout
    const bidPromises = bidRequests.map(request => 
      Promise.race([
        this.sendBidRequest(request),
        this.timeout(this.bidTimeout)
      ])
    );
    
    // Collect all bids, ignore timeouts
    const results = await Promise.allSettled(bidPromises);
    
    return results
      .filter(r => r.status === 'fulfilled')
      .map(r => r.value)
      .filter(bid => bid && bid.price > 0);
  }
}

Caching Strategies

Reduce repeated calculations:

class BidCache {
  constructor(ttl = 300000) { // 5 minute TTL
    this.cache = new Map();
    this.ttl = ttl;
  }
  
  getCachedBid(buyer, leadHash) {
    const key = `${buyer.id}:${leadHash}`;
    const cached = this.cache.get(key);
    
    if (cached && Date.now() - cached.timestamp < this.ttl) {
      return cached.bid;
    }
    
    return null;
  }
  
  cacheBid(buyer, leadHash, bid) {
    const key = `${buyer.id}:${leadHash}`;
    this.cache.set(key, {
      bid: bid,
      timestamp: Date.now()
    });
  }
}

📈 Analytics and Monitoring

Key Metrics

Track auction performance:

const auctionMetrics = {
  // Efficiency metrics
  avgAuctionTime: calculateAverage(auctionTimes),
  bidResponseRate: respondingBuyers / totalBuyers,
  
  // Revenue metrics
  avgWinningBid: calculateAverage(winningBids),
  avgFloorPriceDelta: avgWinningBid - avgFloorPrice,
  fillRate: soldLeads / totalLeads,
  
  // Competition metrics
  avgBiddersPerAuction: calculateAverage(bidderCounts),
  bidSpread: calculateStdDev(allBids),
  winRateByBuyer: calculateWinRates(buyers),
  
  // Quality metrics
  qualityScoreCorrelation: correlate(qualityScores, winningBids),
  conversionByPriceTier: groupByPriceTier(conversions)
};

Real-Time Dashboards

Monitor auction health:

class AuctionDashboard {
  constructor() {
    this.metrics = new RealTimeMetrics();
    this.alerts = new AlertSystem();
  }
  
  updateDashboard(auctionResult) {
    // Update running metrics
    this.metrics.recordAuction(auctionResult);
    
    // Check for anomalies
    if (this.metrics.getResponseRate() < 0.5) {
      this.alerts.trigger('Low bid response rate');
    }
    
    if (this.metrics.getAvgAuctionTime() > 150) {
      this.alerts.trigger('Slow auction performance');
    }
    
    // Update visualizations
    this.updateCharts();
  }
}

💡 Advanced Strategies

Price Discrimination

Charge different prices to different buyers:

function calculateBuyerSpecificPrice(lead, buyer) {
  const basePrice = calculateBasePrice(lead);
  
  // Buyer performance adjustment
  const conversionRate = buyer.metrics.conversionRate;
  const performanceMultiplier = 0.8 + (conversionRate * 0.4);
  
  // Volume commitment discount
  const volumeDiscount = buyer.monthlyCommitment > 10000 ? 0.95 : 1.0;
  
  // Relationship longevity bonus
  const loyaltyDiscount = buyer.accountAge > 365 ? 0.97 : 1.0;
  
  return basePrice * performanceMultiplier * volumeDiscount * loyaltyDiscount;
}

Auction Hybridization

Combine auction types:

function hybridAuction(lead, bids) {
  const qualityScore = lead.qualityScore;
  
  if (qualityScore > 90) {
    // First-price for premium leads
    return firstPriceAuction(bids);
  } else if (qualityScore > 70) {
    // Second-price for standard leads
    return secondPriceAuction(bids);
  } else {
    // Fixed price for lower quality
    return fixedPriceAllocation(bids, lead.floorPrice);
  }
}
