Case Study 1: Multi-Ad Set Performance
A brand is running 3 ad sets on Meta:
Ad Set| Spend| Impressions| Clicks| Purchases| Revenue
Broad| ₹30,000| 3,00,000| 6,000| 120| ₹96,000
Interest| ₹25,000| 2,00,000| 5,000| 150| ₹1,20,000
Lookalike| ₹20,000| 1,00,000| 4,000| 140| ₹1,12,000
Think about:
- Which ad set has the best efficiency vs scale potential?
- Are you optimizing for cheap traffic or quality traffic?
- How would you allocate a ₹1L budget?

Case Study 2: Creative Testing Impact
Same audience, two creatives:
Creative| Impressions| Clicks| Spend| Purchases| Revenue
Video Ad| 2,50,000| 7,500| ₹37,500| 150| ₹1,20,000
Image Ad| 2,50,000| 3,000| ₹30,000| 120| ₹96,000
Think about:

Campaign| Impressions| Clicks| Spend| Purchases| Revenue
X| 3,00,000| 9,000| ₹45,000| 90| ₹72,000
Y| 3,00,000| 6,000| ₹36,000| 120| ₹96,000
Think about:
- Which campaign brings better traffic quality?

Same campaign over time:
Month| Spend| Impressions| Clicks| Purchases| Revenue
Month 1| ₹50,000| 4,00,000| 10,000| 250| ₹2,00,000
Month 2| ₹1,00,000| 6,00,000| 15,000| 300| ₹2,40,000

Meta| ₹60,000| 5,00,000| 12,000| 240| ₹1,92,000
Google| ₹60,000| 2,00,000| 8,000| 300| ₹2,40,000
Think about:
- Which platform has higher intent?
- Which one is better for scaling?
- Should strategy differ across platforms?

Final Thought
Most marketers focus on:
- CTR
- CPC
But real performance comes from understanding the full funnel.

- High CTR doesn’t guarantee sales
- Low CPC doesn’t guarantee profit
- Scaling blindly often breaks performance
