Add a variable for average revenue per conversion

Calculate CTR as clicks divided by impressions

Calculate CPA as total cost divided by conversions

Calculate ROAS as total revenue divided by total cost

💡 Why This Matters

🌍 Real World

Use curly braces to create a dictionary with the exact keys and values.

2

Add average revenue per conversion

Create a variable called avg_revenue_per_conversion and set it to 15.

Digital Marketing

campaign_data = {'impressions': 10000, 'clicks': 500, 'conversions': 50, 'total_cost': 200}
# Create avg_revenue_per_conversion variable and set it to 15
# Your code here

Need a hint?

Just assign the number 15 to the variable avg_revenue_per_conversion.

3

Calculate CTR and CPA

Calculate the click-through rate (CTR) as ctr = campaign_data['clicks'] / campaign_data['impressions'] and the cost per acquisition (CPA) as cpa = campaign_data['total_cost'] / campaign_data['conversions'].

Digital Marketing

campaign_data = {'impressions': 10000, 'clicks': 500, 'conversions': 50, 'total_cost': 200}
avg_revenue_per_conversion = 15
# Calculate ctr and cpa variables
# Your code here

Need a hint?

Divide clicks by impressions for CTR, and total cost by conversions for CPA.

4

Calculate ROAS

Calculate the return on ad spend (ROAS) as roas = (avg_revenue_per_conversion * campaign_data['conversions']) / campaign_data['total_cost'].

Digital Marketing

campaign_data = {'impressions': 10000, 'clicks': 500, 'conversions': 50, 'total_cost': 200}
avg_revenue_per_conversion = 15
ctr = campaign_data['clicks'] / campaign_data['impressions']
cpa = campaign_data['total_cost'] / campaign_data['conversions']
# Calculate roas variable
# Your code here

Need a hint?

Multiply average revenue per conversion by conversions, then divide by total cost.
