1. Digital Marketing Metrics (Formula Cheat Sheet)

Mastering these formulas is crucial for numerical questions.

Metric Formula What it means
Click-Through Rate (CTR) (Clicks / Impressions) × 100 % of people who saw the ad and clicked it.
Conversion Rate (CR) (Conversions / Total Visitors) × 100 % of visitors who took the desired action (buy/signup).
Total Cost Total Clicks × Cost Per Click (CPC) Total money spent on the campaign.
Total Revenue Total Conversions × Avg Revenue per Conv. Total money earned.
ROI (Return on Investment) [(Revenue - Cost) / Cost] × 100 Profitability percentage. High ROI = Highly profitable.
Bounce Rate (Bounced Visitors / Total Visitors) × 100 % of users who left without interacting (Lower is better).
Weighted Average (Sum of [Value × Weight]) / Total Weight Used for overall CTR/Bounce Rate across multiple channels.
Engaged Time Non-Bounced Sessions × Avg Session Time Total time spent by active users.

Quick Intuition:

  • High Bounce Rate (>50%) = Bad landing page or irrelevant traffic.
  • High CTR + Low Conversion = Good Ad, Bad Product Page.
  • High ROI = Marketing is generating solid profit.

✍️ 6. Content Optimization

  2. Keyword Density: Ratio of keywords to total words. Don’t overdo it.
  3. Internal & Outbound Links: Link to your own pages AND authoritative external sources.
  4. Variety: Use Text + Images + Videos + Infographics.

7. Brand Equity & Management

What is a Brand? A name, logo, or design identifying a seller’s goods and differentiating them from competitors (e.g., Apple’s bitten apple, Nike’s swoosh).

Brand Equity: The extra value or premium a brand adds to a product. (Why people pay ₹80,000 for an iPhone instead of ₹20,000 for a generic phone).

The Brand Resonance Pyramid (4 Levels)

How brands build deep emotional connections (Bottom to Top):

  1. Brand Identity (Who are you?): Awareness and recognition.
  2. Brand Meaning (What are you?): Performance (quality) & Imagery (personality).
  3. Brand Response (What about you?): Judgments (credibility) & Feelings (trust/fun).
  4. Brand Resonance (You & Me): Ultimate loyalty, bonding, and advocacy (e.g., Apple fanboys).

⚠️ Pyramid Limitations: Assumes a slow, step-by-step linear progression (ignoring viral overnight success) and over-emphasizes emotional attachment (which isn’t needed for utility products like electricity or toilet paper).

  2. Relevance: Brand fits the customer’s needs.
  3. Performance: Product delivers on its promises.
