📊 Revenue Optimization Features

Dynamic Pricing Engine

// Automatic pricing based on demand
const promotionPricing = {
  peak_hours: {
    spotlight: 149,    // +50% during peak
    top_ads: 199,      
    urgent: 79
  },
  off_peak: {
    spotlight: 99,     // Standard pricing
    top_ads: 149,
    urgent: 49
  }
};

A/B Testing Framework

// Built-in A/B testing for pricing
const experiments = {
  promotion_pricing: ['control', 'variant_a', 'variant_b'],
  checkout_flow: ['standard', 'simplified'],
  homepage_layout: ['grid', 'list', 'card']
};

🛡️ Production Security

SSL/HTTPS (Free with Cloudflare)

# nginx.conf
server {
    listen 443 ssl http2;
    ssl_certificate /etc/ssl/certs/fullchain.pem;
    ssl_certificate_key /etc/ssl/certs/privkey.pem;
    
    # Security headers
    add_header X-Frame-Options "SAMEORIGIN" always;
    add_header X-Content-Type-Options "nosniff" always;
    add_header Referrer-Policy "no-referrer-when-downgrade" always;
    add_header Content-Security-Policy "default-src 'self'" always;
}

Rate Limiting & DDoS Protection

// Cloudflare + Express rate limiting
const rateLimit = require('express-rate-limit');

const limiter = rateLimit({
  windowMs: 15 * 60 * 1000, // 15 minutes
  max: 100, // 100 requests per IP
  message: 'Too many requests, please try again later'
});

app.use('/api', limiter);

Data Protection & GDPR Compliance

// User data encryption
const crypto = require('crypto');
const algorithm = 'aes-256-gcm';

const encrypt = (text) => {
  const cipher = crypto.createCipher(algorithm, process.env.ENCRYPTION_KEY);
  return cipher.update(text, 'utf8', 'hex') + cipher.final('hex');
};

📈 Analytics & Growth Tracking

Real-Time Dashboard

// Revenue tracking
const dailyRevenue = await Transaction.aggregate([
  { $match: { status: 'completed', createdAt: { $gte: today } } },
  { $group: { _id: null, total: { $sum: '$platformFee' } } }
]);

// User growth metrics
const userGrowth = await User.aggregate([
  { $group: { 
    _id: { $dateToString: { format: "%Y-%m-%d", date: "$createdAt" } },
    count: { $sum: 1 }
  }}
]);

Conversion Optimization

// Track user funnel
const funnelMetrics = {
  visits: await Analytics.count({ event: 'page_view' }),
  signups: await User.count(),
  listings: await ProductListing.count(),
  transactions: await Transaction.count({ status: 'completed' })
};

const conversionRate = (transactions / visits * 100).toFixed(2);

🔄 Automated Revenue Features

Auto-Promotion Suggestions

// Suggest promotions based on listing performance
const suggestPromotion = async (listingId) => {
  const listing = await ProductListing.findById(listingId);
  const daysSinceCreated = (Date.now() - listing.createdAt) / (1000 * 60 * 60 * 24);
  
  if (listing.views < 10 && daysSinceCreated > 2) {
    return {
      suggested: 'spotlight',
      reason: 'Low visibility - boost with Spotlight',
      discount: 20 // 20% discount to encourage purchase
    };
  }
};

Dynamic Subscription Upsells

// Smart subscription recommendations
const upsellSubscription = async (userId) => {
  const user = await User.findById(userId);
  const listingsCount = await ProductListing.count({ user: userId });
  
  if (listingsCount >= 5 && user.subscriptionTier === 'basic') {
    return {
      recommended: 'pro',
      savings: '₹200/month vs individual promotions',
      features: ['Unlimited listings', '2 free promotions', 'Priority support']
    };
  }
};

💡 Monetization Optimization

Pricing Psychology

// Psychological pricing strategy
const pricingTiers = {
  spotlight: {
    original: 100,
    promotional: 99,  // ₹99 vs ₹100 (psychological pricing)
    savings: '₹1 saved'
  },

const festivalCampaigns = {
  diwali: {
    discount: 30,

  },
  new_year: {
    bonus_features: true,
    double_duration: true,
    target_revenue: '₹3,00,000'
  }
};

📱 Mobile-First Strategy

Progressive Web App (PWA)

// Service worker for offline functionality
const CACHE_NAME = 'budmatching-v1';
const urlsToCache = [
  '/',
  '/listings',
  '/static/js/bundle.js',
  '/static/css/main.css'
];

self.addEventListener('install', (event) => {
  event.waitUntil(
    caches.open(CACHE_NAME)
      .then((cache) => cache.addAll(urlsToCache))
  );
});

App-like Experience

  "start_url": "/",
  "display": "standalone",
  "background_color": "#ffffff",
