Channel Performance Tracking

# Marketing Budget Performance Calculator
class MarketingBudgetTracker:
    def __init__(self):
        self.channels = {}

    def add_channel(self, name, budget, spend, revenue, conversions):
        self.channels[name] = {
            'budget': budget,
            'spend': spend,
            'revenue': revenue,
            'conversions': conversions,
            'roas': revenue / spend if spend > 0 else 0,
            'cpa': spend / conversions if conversions > 0 else 0,
            'budget_utilization': (spend / budget) * 100
        }

    def calculate_efficiency_score(self, channel):
        data = self.channels[channel]
        # Weighted score: ROAS (40%), Budget Utilization (30%), Volume (30%)
        roas_score = min(data['roas'] / 4.0, 1.0) * 40  # Normalize to target ROAS of 4
        util_score = min(data['budget_utilization'] / 100, 1.0) * 30
        volume_score = min(data['conversions'] / 100, 1.0) * 30  # Normalize to 100 conversions
        return roas_score + util_score + volume_score

Channel-Specific Budget Guidelines

Performance Marketing Budgets

Google Ads: Start with $50-100/day minimum per campaign for data significance
Facebook Ads: $20-50/day per ad set, scale based on CPA performance
LinkedIn Ads: Higher minimums ($100+/day) due to premium audience costs

Content & Brand Marketing

Content Creation: 15-20% of total budget, focus on evergreen assets
Video Production: Allocate 30-40% more budget than static content
Brand Campaigns: Plan for 3-6 month sustained investment periods

Budget Optimization Strategies

Performance-Based Reallocation

// Budget reallocation algorithm
function reallocateBudget(channels, totalBudget, performancePeriod) {
    const sortedChannels = channels.sort((a, b) => b.roas - a.roas);
    const topPerformers = sortedChannels.slice(0, Math.ceil(channels.length * 0.6));
    const underperformers = sortedChannels.slice(Math.ceil(channels.length * 0.6));

    // Increase top performer budgets by 20%, decrease underperformers by 15%
    topPerformers.forEach(channel => {
        channel.newBudget = Math.min(channel.budget * 1.2, totalBudget * 0.4); // Cap at 40% of total
    });

    underperformers.forEach(channel => {
        channel.newBudget = Math.max(channel.budget * 0.85, totalBudget * 0.05); // Floor at 5% of total
    });

    return channels;
}

Seasonal Budget Adjustments

Q4 Holiday Season: Increase performance budgets by 25-40%
B2B Patterns: Reduce budgets in December, August; increase in January, September
Consumer Patterns: Peak during holiday seasons, back-to-school, summer

ROI Measurement & Attribution

Multi-Touch Attribution Model

-- Marketing Attribution Query
WITH touchpoint_revenue AS (
  SELECT 
    channel,
    campaign,
    SUM(attributed_revenue) as revenue,
    SUM(spend) as spend,
    COUNT(DISTINCT conversion_id) as conversions
  FROM marketing_attribution 
  WHERE date >= DATE_SUB(CURRENT_DATE(), INTERVAL 30 DAY)
  GROUP BY channel, campaign
)
SELECT 
  channel,
  revenue,
  spend,
  revenue/spend as roas,
  spend/conversions as cpa,
  (revenue - spend)/spend * 100 as roi_percentage
FROM touchpoint_revenue
WHERE spend > 0
ORDER BY roas DESC;

Budget Planning Best Practices

Monthly Budget Reviews

Performance Analysis: Compare actual vs. projected ROAS
Spend Pacing: Track budget utilization vs. timeline
Channel Optimization: Reallocate based on performance trends
Competitive Analysis: Adjust for market changes

Risk Management

Buffer Allocation: Reserve 10-15% for unexpected opportunities
Performance Floors: Set minimum ROAS thresholds for continued investment
Diversification: Don't allocate more than 40% to any single channel

Scaling Strategies

Test Small: Start with 10-20% of intended budget for new channels
Scale Gradually: Increase budgets by 20-30% weekly for winning campaigns
Monitor Saturation: Watch for declining ROAS as spend increases

Advanced Budget Optimization

Lifetime Value Integration

# LTV-based budget optimization
def calculate_ltv_budget_allocation(customer_ltv, acquisition_cost, payback_period):
    max_cpa = customer_ltv / 3  # Conservative 3:1 LTV:CAC ratio
    monthly_budget_cap = max_cpa * target_acquisitions

    if payback_period <= 3:  # Months
        return monthly_budget_cap * 1.2  # Aggressive scaling
    elif payback_period <= 6:
        return monthly_budget_cap * 1.0  # Standard scaling
    else:
        return monthly_budget_cap * 0.8  # Conservative scaling

Cross-Channel Synergy Planning

Upper Funnel: Brand campaigns increase lower-funnel efficiency by 15-25%
Retargeting: Allocate 20-30% of acquisition budget to retargeting
Email Marketing: Maintain 1:10 ratio with paid acquisition spend

Always provide specific budget recommendations based on business size, industry, and growth stage. Include rationale for allocations and provide clear metrics for measuring success.
