Core Digital Marketing Metrics

 These key acronyms form the foundation of performance digital marketing, covering everything from ad engagement to profitability. They are essential for measuring the efficiency, cost-effectiveness, and long-term value of marketing campaigns. 

Core Digital Marketing Metrics

• CTR (Click-Through Rate): The percentage of people who click on an ad or link after seeing it (Impressions).
  • Formula: (Clicks / Impressions) x 100
  • Significance: Measures the relevance, appeal, and engagement of your ad creative.
• CVR (Conversion Rate): The percentage of users who clicked on an ad and then completed a desired action (e.g., purchase, signup).
  • Formula: (Conversions / Clicks) x 100
  • Significance: Measures the effectiveness of your landing page, offer, and user experience.
• CPA (Cost Per Acquisition/Action): The total cost to acquire a new customer or lead.
  • Formula: Total Cost / Total Conversions
  • Significance: Measures the cost-effectiveness of your campaigns.
• ROAS (Return on Ad Spend): The gross revenue generated for every dollar spent on advertising.
  • Formula: Total Revenue from Ads / Total Ad Spend
  • Significance: Measures the immediate profitability of a specific ad campaign.
• CAC (Customer Acquisition Cost): The total expense of acquiring a new customer, often including marketing, sales, and overhead costs.
  • Formula: Total Marketing + Sales Cost / Number of New Customers
  • Significance: Measures the cost to gain a customer across all channels (a business-level metric).
• LTV or CLV (Customer Lifetime Value): The total revenue or profit expected from a customer throughout their entire relationship with a business.
  • Formula: Customer Value x Average Customer Lifespan
  • Significance: Predicts long-term business profitability and determines how much you can afford to spend on acquisition. 

Key Relationships & Interpretations

• LTV:CAC Ratio: A crucial metric for long-term sustainability; generally, a 3:1 ratio (LTV is 3x CAC) is considered healthy.
• High CTR, Low CVR: Indicates your ad is engaging, but the landing page or offer is not convincing visitors to convert.
• Low CTR, High CVR: Suggests your targeting is very precise, but the ad creative needs to be more compelling to increase volume.
• ROAS vs. MER: ROAS measures campaign-level effectiveness, while Marketing Efficiency Ratio (MER) measures overall, total-channel profitability.
