Post-Launch Monitoring Setup

Monitoring-Dashboard konfigurieren

In den ersten 12 Wochen nach dem Launch benötigen Sie tägliches bis wöchentliches Monitoring. Hier die essentiellen Metriken und Tools:

Automatisierte Reporting einrichten

# Google Analytics Reporting API - Python Script
import google.analytics.reporting.v4 as ga_reporting

def get_relaunch_metrics(property_id, start_date, end_date):
    """
    Automatisierter Relaunch-Report
    Vergleicht aktuelle Metriken mit Pre-Launch Baseline
    """
    
    # Metrics für Relaunch-Tracking
    metrics = [
        {'expression': 'ga:sessions'},
        {'expression': 'ga:organicSearches'},
        {'expression': 'ga:goalCompletionRate'},
        {'expression': 'ga:bounceRate'},
        {'expression': 'ga:avgSessionDuration'}
    ]
    
    # Dimensions für detaillierte Analyse
    dimensions = [
        {'name': 'ga:channelGrouping'},
        {'name': 'ga:deviceCategory'},
        {'name': 'ga:landingPagePath'}
    ]
    
    # API-Request
    response = analytics.reports().batchGet(
        body={
            'reportRequests': [{
                'viewId': property_id,
                'dateRanges': [{'startDate': start_date, 'endDate': end_date}],
                'metrics': metrics,
                'dimensions': dimensions
            }]
        }
    ).execute()
    
    return process_response(response)

# Automated Alert System
def check_critical_metrics(current_data, baseline_data):
    alerts = []
    
    # Traffic Drop Alert
    traffic_change = (current_data['sessions'] - baseline_data['sessions']) / baseline_data['sessions']
    if traffic_change < -0.3:  # 30% Drop
        alerts.append(f"CRITICAL: Traffic drop of {traffic_change:.1%}")
    
    # Conversion Rate Alert  
    conversion_change = current_data['conversion_rate'] - baseline_data['conversion_rate']
    if conversion_change < -0.05:  # 5% absolute drop
        alerts.append(f"WARNING: Conversion rate drop of {conversion_change:.2%}")
    
    return alerts

ROI-Bewertung & Erfolgsmessung

Relaunch-ROI berechnen

# ROI-Berechnung Template (nach 6 Monaten)

# Kosten-Aufstellung
relaunch_costs = {
    'agency_fees': 25000,           # Agentur/Freelancer
    'development': 15000,           # Technical Implementation  
    'content_creation': 8000,       # Content-Migration & Erstellung
    'tools_licenses': 2000,         # SEO-Tools, Analytics etc.
    'internal_time': 12000,         # Team-Aufwand (Stunden * Stundensatz)
    'total_investment': 62000
}

# Revenue-Impact (6 Monate nach Launch)
pre_launch_metrics = {
    'monthly_organic_revenue': 45000,
    'monthly_organic_leads': 180,
    'avg_customer_value': 1200
}

post_launch_metrics = {
    'monthly_organic_revenue': 58000,  # +29% Improvement
    'monthly_organic_leads': 245,      # +36% Improvement  
    'avg_customer_value': 1350        # +12% durch bessere Qualifikation
}

# ROI-Berechnung
monthly_revenue_increase = post_launch_metrics['monthly_organic_revenue'] - pre_launch_metrics['monthly_organic_revenue']
six_month_additional_revenue = monthly_revenue_increase * 6  # 78,000 EUR
annual_projection = monthly_revenue_increase * 12           # 156,000 EUR

roi_6_months = (six_month_additional_revenue - relaunch_costs['total_investment']) / relaunch_costs['total_investment']
# ROI = (78,000 - 62,000) / 62,000 = 25.8% in 6 Monaten

payback_period = relaunch_costs['total_investment'] / monthly_revenue_increase
# Payback = 62,000 / 13,000 = 4.8 Monate
