Implementasi Tracking

Basic Logging:

javascript

const stats = {
    daily: {},
    getToday() {
        const today = new Date().toISOString().split('T')[0];
        if (!this.daily[today]) {
            this.daily[today] = {
                messagesReceived: 0,
                messagesSent: 0,
                uniqueUsers: new Set(),
                conversations: 0,
                ordersStarted: 0,
                ordersCompleted: 0,
                errors: 0
            };
        }
        return this.daily[today];
    }
};

client.on('message', async msg => {
    const today = stats.getToday();
    
    // Track incoming message
    today.messagesReceived++;
    today.uniqueUsers.add(msg.from);
    
    const startTime = Date.now();
    
    try {
        const response = await processMessage(msg);
        await msg.reply(response);
        
        // Track outgoing message
        today.messagesSent++;
        
        // Track response time
        const responseTime = Date.now() - startTime;
        trackResponseTime(responseTime);
        
    } catch (error) {
        today.errors++;
        console.error(error);
    }
});

Conversation Tracking:

javascript

const conversations = new Map();

function trackConversationStart(phone) {
    conversations.set(phone, {
        startedAt: Date.now(),
        steps: ['start'],
        completed: false
    });
}

function trackConversationStep(phone, step) {
    const conv = conversations.get(phone);
    if (conv) {
        conv.steps.push(step);
        conv.lastActivity = Date.now();
    }
}

function trackConversationEnd(phone, completed) {
    const conv = conversations.get(phone);
    if (conv) {
        conv.endedAt = Date.now();
        conv.completed = completed;
        conv.duration = conv.endedAt - conv.startedAt;
        
        // Save to database for analysis
        saveConversationAnalytics(phone, conv);
        
        conversations.delete(phone);
    }
}

// Usage
client.on('message', async msg => {
    if (isNewConversation(msg.from)) {
        trackConversationStart(msg.from);
    }
    
    trackConversationStep(msg.from, detectStep(msg.body));
    
    if (isConversationEnd(msg.body)) {
        trackConversationEnd(msg.from, true);
    }
});

Funnel Tracking:

javascript

const funnelSteps = ['greeting', 'inquiry', 'price_check', 'add_to_cart', 'checkout', 'payment', 'completed'];

const funnelStats = {};

function initFunnelStats() {
    funnelSteps.forEach(step => {
        funnelStats[step] = { count: 0, dropoffs: 0 };
    });
}

function trackFunnelStep(phone, step) {
    funnelStats[step].count++;
    
    // Track dropoff from previous step
    const stepIndex = funnelSteps.indexOf(step);
    if (stepIndex > 0) {
        const prevStep = funnelSteps[stepIndex - 1];
        const dropoffRate = 1 - (funnelStats[step].count / funnelStats[prevStep].count);
        funnelStats[prevStep].dropoffs = dropoffRate;
    }
}

// Analysis
function getFunnelReport() {
    let report = '📊 FUNNEL REPORT\n\n';
    
    funnelSteps.forEach((step, i) => {
        const stats = funnelStats[step];
        const convRate = i === 0 ? '100%' : 
            ((stats.count / funnelStats[funnelSteps[0]].count) * 100).toFixed(1) + '%';
        
        report += `${step}: ${stats.count} (${convRate})\n`;
        
        if (stats.dropoffs > 0.3) {
            report += `  ⚠️ High dropoff: ${(stats.dropoffs * 100).toFixed(1)}%\n`;
        }
    });
    
    return report;
}

Actionable Insights

Identify Problems:

🔍 COMMON ISSUES TO LOOK FOR:

1. High drop-off at specific step
   → Step terlalu confusing/panjang

2. Low bot resolution rate
   → Bot tidak paham banyak queries

3. High human handover
   → Bot perlu lebih banyak training

4. Long response times
   → Performance optimization needed

5. Negative sentiment spike
   → Check recent changes/issues

Improvement Actions:

🛠️ OPTIMIZATION ACTIONS:

Issue: Drop-off at step X
Action: Simplify step, add more guidance

Issue: "Not understood" responses high
Action: Add more keyword variations

Issue: Slow response
Action: Cache common responses, optimize code

Issue: Low CSAT
Action: Review negative feedback, improve responses
