Performance Marketing That Proves Itself
At Proof3, we believe the era of marketing by instinct is over. Too many businesses waste budget chasing ideas that should work instead of knowing what does work. Our approach to performance marketing is built on a simple but powerful principle: every decision should be grounded in evidence. We test, measure, and optimise relentlessly to remove the guesswork and uncover what truly drives growth.
Whether you are scaling an e-commerce business, launching a SaaS product, or improving lead generation, we deliver strategies that are tailored, agile, and focused entirely on results. If you want to move faster and smarter, with full clarity on the return of every marketing dollar, you are in the right place.
“We’ve lowered our cost of acquisition through paid channels without reducing the volume or quality of clicks.”
Just Kampers
Case study – Maximising paid media efficiency for Just Kampers
Just Kampers faced escalating paid search costs that were eating into profitability without delivering proportional returns. Our team tackled the problem by streamlining and restructuring their paid media campaigns. We removed underperforming keywords and shifted budget toward high-converting terms, ensuring every pound worked harder. The result was a significant 52% reduction in cost per acquisition (CPA), alongside a 25% increase in conversions. By continually testing and optimising performance, we helped Just Kampers regain control of their paid spend while driving measurable, sustained growth.

Surveys are a fantastic way to gather feedback, but incentives don’t always lead to honest answers.

One of the simplest ways to speed up your Shopify store is to optimise your images.
