Paid Ad Campaign Case Study
Part of the Digital Marketing Roadmap
In short
Anyone can spend ad money. A paid ad case study proves you can spend it on purpose: right audience, tested creatives and results measured against a clear goal.
Document a real or mock paid campaign end-to-end — targeting, creative, budget, and results (real or realistically projected) — directly building on Phase 6's campaign project.
Think of it like this
The loudspeaker auto-rickshaw
A shop owner hires an auto with a loudspeaker to announce his sale. A smart owner also picks which colonies to cover, tries two announcements, and counts how many people mention the auto at the counter. That's targeting, creative testing and measurement. Your case study tells that story.
Watch it happen
Structure of a paid campaign case study
1/6One clear goal with a target: 200 webinar sign-ups under ₹60 each.
The big ideas
What you need to know
Goal before metrics
Start with the business goal. Clicks only matter if they lead to what you wanted.
Show a test
Two audiences or two creatives compared shows you think like a performance marketer.
Core maths
Include CPC, conversion rate, CPA and, for sales, ROAS. Show how you calculated them.
Real or mock, say which
A small real campaign is great. If it's a mock, label projected numbers honestly.

Walk through the code
1 Spend Clicks Sign-ups CPC CPA2Ad A 5000 620 62 =B2/C2 → ₹8.1 =B2/D2 → ₹80.63Ad B 5000 540 98 =B3/C3 → ₹9.3 =B3/D3 → ₹51.01/2Ad A: more clicks, but fewer of them signed up.
Ad A got cheaper clicks, but Ad B got far cheaper sign-ups. Showing this kind of insight is the heart of a good paid case study.
Save yourself the pain
Common mistakes
Oops
Celebrating a low CPC while sign-ups were poor.
Do this instead
Judge ads on the campaign goal, like cost per sign-up or ROAS.
Oops
Presenting made-up results as real.
Do this instead
Clearly label mock campaigns and projected numbers. Interviewers will ask.
Your mission
Plan your campaign one-pager
Quick check
Ad A has a lower CPC but a higher CPA than Ad B. The goal is sign-ups. Which is better?
Go deeper
- 1Use your Phase 6 mock campaign as the foundation, adding results if you ran it for real.
- 2Include your targeting logic and 2-3 ad variations you tested.
- 3If mock (unpublished), be explicit that results are projected, not real, and explain your assumptions.
