CONVERSION RATE OPTIMISATION MONTH: Building a culture of experimentation in high-growth marketing teams
Conversion rate optimisation (CRO) is a strategic priority for any digital team looking to scale sustainably. But while tools and tactics matter, the most powerful driver of CRO success isn’t technology, it’s culture. High-performing marketing teams are embracing test-and-learn mindsets that place experimentation at the heart of growth.
In the UK’s most successful brands, CRO has evolved from a set of standalone A/B tests to a continuous process that involves UX designers, copywriters, data analysts, developers, and product managers. These teams share one goal: use insight-driven hypotheses to improve user experience and increase conversion rates, whether on websites, apps, landing pages, or campaign funnels.
The first step is democratising experimentation. Instead of a central CRO team owning all tests, forward-thinking organisations are training cross-functional squads to run and interpret their own experiments. This not only increases test velocity but fosters shared ownership of performance outcomes.
Data literacy is key. Marketers and creatives must understand how to read test results, determine statistical significance, and draw actionable insights. Many brands now run in-house training sessions or create experimentation playbooks to ensure consistency in test design and analysis.
Successful teams also adopt clear prioritisation frameworks. Not every test has to reinvent the wheel. Frameworks like PIE (Potential, Importance, Ease) or ICE (Impact, Confidence, Ease) help teams focus on experiments with the greatest upside. High-impact areas include checkout flows, form fields, navigation menus, hero copy, and call-to-action buttons.
Importantly, not every test needs to ‘win’. Even inconclusive or negative results offer learning opportunities, revealing user preferences, device-specific behaviours, or areas needing deeper qualitative research.
Scaling comes with process. As experimentation matures, brands are investing in shared CRO dashboards, test libraries, and centralised knowledge hubs. These tools prevent duplicate efforts, enable benchmarking, and accelerate iteration.
Ultimately, building a culture of experimentation means celebrating curiosity, speed, and small wins, while keeping the customer at the centre. Brands that embed this mindset build teams equipped for long-term, data-driven growth.
