From isolated A/B tests to unbeatable customer journeys

Conversion Rate Optimisation (CRO) was once synonymous with simple A/B testing: button A versus button B, page X versus page Y. Back then, small tweaks and isolated experiments were enough to achieve results. Today, that approach is outdated. While it can still serve as a starting point in some situations, real impact now requires a broader and more integrated strategy.

The goal: eliminate friction, exceed expectations, and add value at every touchpoint

From A/B testing to strategic customer-centricity

Running random A/B tests inspired by generic “best practices” is no longer enough. Successful optimisation starts with a deep understanding of your audience:

  • What motivates them?
  • Which barriers do they experience?
  • What rational and emotional factors influence their purchasing decisions?

Whether someone is buying a suitcase or building a garden shed, only the customer can provide these crucial insights. That is why integrating structural customer research into your strategy is essential. Interviews, surveys, and behavioural analysis provide valuable information that drives meaningful optimisation.

Real optimisation also requires a fundamental shift in mindset across the organisation. Customer-centricity should not remain a marketing slogan. It needs to be embedded in every team, from development to customer support. Everyone shares responsibility for delivering an outstanding customer journey.

Automation, personalisation, and smart A/B testing

The true power of modern CRO lies in turning customer data into practical applications:

  • Automation: relevant and automated communication at the right moment
  • Personalisation: dynamic content tailored to behaviour, preferences, and audience segments
  • Strategic A/B testing: continuous validation of optimisations across the entire customer journey, not just individual pages
