Understanding SEO & PPC Results

After calculation, you’ll see three key outputs:

• Rolling Average 1: Represents the average performance over the first three months.
• Rolling Average 2: Represents the average performance over the latest three months.
  
• Rolling Growth %: Indicates the relative change between both rolling averages.

Industry Benchmarks

Values vary based on competitiveness, market size, and customer acquisition goals.

Practical Example

Example Data:
M1 = ₹10,00,000 | M2 = ₹11,00,000 | M3 = ₹12,00,000 | M4 = ₹13,50,000

Step 1:
Rolling Average 1 = (10,00,000 + 11,00,000 + 12,00,000) ÷ 3 = ₹11,00,000

Step 2:
Rolling Average 2 = (11,00,000 + 12,00,000 + 13,50,000) ÷ 3 = ₹12,16,667

Step 3:
Rolling Growth % = ((12,16,667 – 11,00,000) ÷ 11,00,000) × 100 = +10.6%

Interpretation:
Growth is accelerating by 10.6% — a strong, sustained upward trend indicating consistent performance improvements over time.

Tips to Improve Rolling Growth

• Optimise Continuously: Focus on consistency rather than short bursts of growth.
• Balance Acquisition & Retention: Rolling averages reward steady retention as much as acquisition spikes.
• Track with Complementary Metrics: Pair this analysis with CAC, CLTV, and conversion rate to get a complete picture.
  
• Visualise Your Trendline: Plot rolling growth percentages across months to show long-term momentum.
