The MahimaJaiswal difference: a complete story, not just a data point
My approach to marketing case studies is different because my process is different. My case studies show a complete story built on three key principles:
I Focus on Business Metrics, Not Vanity Metrics. My case studies don't just show 'impressions' or 'likes.' I draw a direct line from my strategy to the numbers that a CEO cares about. You'll see how I generated +£250K in incremental revenue in a year, or how I doubled a B2B conversion rate from 4.5% to 9%. That's far more effective than just showing a high click-through rate.
I Show the Entire Funnel, Not Just One Action. My work doesn't stop at lead-gen. My case studies demonstrate how I optimise the entire customer journey by partnering with sales and solutions teams. That's why I can show results like lowering customer churn from 18% to 12% or boosting year-end retention from 20% to 50%. I'm not just showing how I acquired a customer; I'm showing how I kept them.
I Demonstrate an Adaptive System, Not a One-Time Report. The most effective marketing isn't 'set it and forget it.' I build tactical reporting models and KPI dashboards from the start. My case studies show how I use tools like Power BI and Google Data Studio to enable weekly course corrections, which is how I've been able to reduce cost-per-lead by 15% mid-campaign.

Challenge: turning a 'leaky bucket' into a growth engine
A great example of a complex challenge comes from my time as Marketing Manager at Precision Bearing Corporation.
When I joined, the immediate challenge wasn't just about getting new leads; it was about keeping them. We had a classic 'leaky bucket' problem: our customer churn was unacceptably high at 18%, and the client onboarding process was slow and inefficient. The team was focused on top-of-funnel lead generation, but we were losing customers almost as fast as we were getting them. The challenge was to fix the leak, not just pour more water in.
My strategy had to be twofold, and it went beyond just running more ads:
Customer Journey Optimization: First, I knew we couldn't 'out-market' a bad experience. I had to address the problem at its source. I collaborated directly with the sales and solutions teams to map the entire customer journey, from the moment a lead converted to when they were fully onboarded. This was a challenge of cross-functional leadership. We identified the specific friction points that caused delays and frustration, and we worked to re-engineer that process.
Data-Driven Feedback Loop: Second, to make this sustainable, I knew we couldn't fix what we couldn't measure in real-time. I constructed a tactical reporting model in Power BI. This wasn't just a monthly report; it was a dynamic tool that monitored our performance against revenue targets. This was the game-changer. It allowed for weekly course correction and gave us immediate visibility into whether our journey optimisations were actually working.
The results proved this was the right approach. By shifting our focus from 'more leads' to a 'better customer experience,' we achieved two critical, related victories: we accelerated client onboarding by 15% and, most importantly, we lowered that high churn rate from 18% all the way down to 12%.
It was a powerful case study in how data-driven journey optimization can directly reduce churn and, by keeping the customers we worked so hard to get, reduced our cost-per-lead by 15% as a direct result.

The results speak for themselves: revenue, leads, and retention
Based on my experience, I'm a results-driven marketer, so I focus on the metrics that drive a business forward. My case studies are built to reflect this, moving from top-of-funnel "awareness" all the way down to "retention" and "revenue."
Here’s the kind of results I typically achieve and how I reflect them in my case studies:
Increased Sales & Revenue (The Bottom Line): This is my top priority. My case studies show a direct link between my marketing strategies and the company's revenue. This is reflected as:
- +£250K in incremental revenue generated in a single year.
- +£100K in new revenue within six months from launching new product lines.
- Doubling the B2B conversion rate from 4.5% to 9%, proving that I'm not just bringing in traffic, I'm turning that traffic into sales.
Lead Generation & Pipeline Growth (The Engine): I build a predictable and efficient engine for sales. My case studies don't just show a vague number of "leads," they show:
- A 30% lift in overall B2B leads.
- More importantly, a 15% increase in qualified leads, which shows I'm targeting the right people.
- A 15% reduction in the cost-per-lead, which proves my campaigns are getting more efficient over time.
Customer Retention & Loyalty (The 'Leaky Bucket' Fix): It's far more expensive to get a new customer than to keep one. My case studies demonstrate my expertise in full-funnel marketing:
- A 25% increase in customer retention across the board.
- In one case, a dramatic jump in year-end retention from 20% to 50%.
- Lowering customer churn from 18% to 12% by optimizing the customer journey and onboarding process.
Brand Awareness & Organic Traffic (The Foundation): This is where growth starts. But I don't just track 'impressions' as a vanity metric. I track it as a driver for the other goals. My case studies show:
- 60% growth in organic monthly traffic (from 6K to 9K) by implementing a data-informed content strategy.
- Campaigns that generate 1M+ impressions but are held accountable to a high 10% average CTR.
Confidence in results: the key takeaway
When a potential client finishes reading one of my case studies, I want them to have one feeling above all else: confidence. I want them to feel a specific, deep-seated confidence that:
- I see their entire business, not just a single marketing channel. They should see that I don't just report on 'impressions' or 'traffic,' but on the metrics they truly care about: +£250K in revenue, a 25% increase in customer retention, and a 15% reduction in cost-per-lead. I want them to feel, 'She gets it. She's focused on my bottom line.'
- I don't guess; I analyze. They should see the evidence of the reporting models in Power BI and the KPI dashboards in Google Data Studio. I want them to feel, 'She has a system. She's not just throwing things at the wall; she measures, she adapts, and she's in control.'
- I solve the whole problem, not just one piece of it. When they read about me lowering customer churn from 18% to 12%, I want them to feel, 'She doesn't just fill the top of the funnel and walk away. She's a strategic partner who understands the entire customer journey, from acquisition right through to onboarding and retention.'
The key takeaway I want them to have is: 'This is a data-driven, full-funnel partner who is relentlessly focused on my business's growth.' I want them to close the case study and think, 'Okay, she's the one who can actually deliver.'
