Finding the right balance between growth and costs for Weltechniek
At the beginning of 2025, Weltechniek set a clear goal for their Google Ads strategy: push harder on growth while keeping costs under control. They wanted to understand exactly how far they could scale without profitability taking a hit.
The campaigns were already performing well, but the question was how to maximize growth without letting costs spiral. It was time to test the limits in a structured way.
The challenge was clear. Achieve strong growth while keeping costs in check and protecting healthy profit margins.
Weltechniek is a leading player in the installation and ventilation sector. Their team came to us with a clear objective: grow aggressively, but always with profitability as the foundation.
How we grew Weltechniek's gross profit by 137%
The situation:
Weltechniek wanted to scale their Google Ads to drive stronger growth, but it was unclear how far they could push without profitability suffering.
As budgets increased, part of the growth proved to be driven by spend rather than efficiency. The campaigns delivered results, but the data showed where performance started to decline as costs went up.
For Weltechniek, profitable growth was the main priority. The challenge was to find the point where scaling further stopped adding real value and started eating into margins.
Our approach:
Q1: Aggressively scaled to test the limits
In the first phase, budgets were significantly increased to understand how the market would respond. This led to strong growth, but also revealed that part of the results came from increased spend rather than improved efficiency.Q2: Focused on controlled, profitable growth
In the second phase, the strategy shifted toward maintaining momentum while tightening cost control. This created a better balance between performance and spend, with healthier margins and stronger cost efficiency.Q3: Scaled back strategically to restore margins
In the third phase, impressions and clicks were deliberately reduced. The data showed that extra traffic brought diminishing returns. By cutting expensive, low-converting clicks, profitability was fully restored without sacrificing core performance.
The Results
- Since scaling the campaigns at the start of 2025, gross profit increased by 137% in Q1 and 26% in Q2.
- Conversions grew by 90% in Q1 and 47% in Q2, supported by a 65% increase in clicks.
- When costs surged by 134% in Q1, the data made it clear where growth was being bought instead of earned. In Q3, we deliberately scaled back; impressions dropped by 33% and clicks by 22%.
- This shift brought costs down by 10%, improved CPA by 2%, and restored profit margins.
Weltechniek now has a clear strategy to scale aggressively when it matters and keep daily operations focused on efficient, profitable growth.
The overall results:
- Costs down 10%
- CPA improved 2%
- Profit margins restored
