A/B Testing

Compare Variants. Understand Behaviour. Validate Decisions.

A/B testing reveals which variant performs better in a real usage context. Two versions of a digital product are shown in parallel and compared based on their impact on behaviour, interaction, and conversion.

This can include testing different wording, layouts, processes, or call-to-actions.

We do not view the results as isolated metrics alone.

We analyse them in the context of the actual user experience. This makes it visible which variant creates orientation, supports processes, and helps users reach their goals more efficiently.

A/B testing helps organisations optimise digital products based on data, reduce decision-making risks, and better understand user behaviour.

When Does A/B Testing Make Sense?

A/B testing is particularly useful when:

  • Different variants need to be compared
  • Conversion rates should be improved
  • There is uncertainty about the better solution
  • Design or content decisions need validation
  • Processes should be optimised
  • New features are introduced
  • Users abandon processes
  • Data-driven optimisation is required

The method is especially relevant for:

  • Websites
  • Landing pages
  • E-commerce
  • SaaS products
  • Apps
  • Digital platforms
  • Self-service solutions
  • Complex B2B systems

What Is Analysed in A/B Testing?

In an A/B test, we analyse aspects such as:

  • Click behaviour
  • Conversion rates
  • Interactions
  • Decision-making behaviour
  • Process drop-offs
  • Usage patterns
  • Clarity of content
  • Process efficiency

Depending on the research objective, we may compare:

  • Different layouts
  • Alternative texts or headlines
  • Call-to-actions
  • Navigation concepts
  • Forms
  • Process steps
  • Visual hierarchies
  • Product presentations

We do not only analyse which variant performs better.

We also identify why users react differently.

Our Approach to A/B Testing

1. Define Objectives and Hypotheses

Together, we define:

  • Goals and KPIs
  • Relevant target groups
  • Critical processes
  • Hypotheses and variants
  • Success criteria

This creates a test design aligned with real business goals and usage situations.

2. Develop and Prepare Variants

We support:

  • Definition of test variants
  • Formulation of hypotheses
  • Structuring the test setup
  • Selection of relevant KPIs
  • Preparation of the technical implementation

We can test:

  • Layouts
  • Content
  • UX flows
  • Forms
  • Call-to-actions
  • Navigation concepts
  • Product pages
  • Self-service processes

3. Conduct Testing in a Real Usage Context

The variants are deployed in parallel during live operation.

We analyse:

  • Behaviour
  • Interactions
  • Conversion
  • Drop-offs
  • Usage patterns
  • Differences between target groups

Depending on the objectives, we complement quantitative data with qualitative insights from:

  • Usability testing
  • Interviews
  • Behaviour analytics
  • Session recordings

This creates a more complete understanding of the user experience.

4. Analyse Results and Provide Recommendations

The results are evaluated and interpreted in a structured way.

We identify:

  • Differences in behaviour and interaction
  • Effects on conversion and processes
  • Comprehension issues
  • Optimisation potential
  • Risks and uncertainties

Based on these insights, we provide concrete recommendations on which variant should be continued or further optimised.

Your Input

For A/B testing, we typically require:

  • Alignment on the variants or research questions to be tested
  • Access to the product or relevant interface

What You Receive

You receive:

  • Data-driven comparisons of variants in real usage contexts
  • Visible insights into impacts on behaviour and interaction
  • Concrete optimisation recommendations
  • Transparent decision-making foundations
  • Insights into usage and conversion
  • Prioritised recommendations for action

Why A/B Testing Matters Economically

Many decisions in digital projects are based on assumptions.

A/B testing helps to:

  • Reduce risks in decision-making
  • Improve conversion rates systematically
  • Identify optimisation potential
  • Detect poor decisions early
  • Validate investments through data
  • Better understand user behaviour

Especially for digital products with high reach, even small improvements can have a significant impact on usage, efficiency, and business success.

Frequently Asked Questions About A/B Testing

What Is an A/B Test?

An A/B test compares two different variants of a digital product. The goal is to identify which variant performs better and why users respond differently.

What Can Be Tested?

Examples include:

  • Layouts
  • Texts
  • Call-to-actions
  • Forms
  • Navigation concepts
  • Processes
  • Product pages
  • Visual elements

How Long Does an A/B Test Take?

The duration depends on traffic, target groups, and the research objective.

A sufficiently large data set is essential to ensure reliable interpretation of the results.

Is a Purely Quantitative Test Enough?

Not always.

Numbers often show which variant performs better. Qualitative methods additionally help explain why differences occur.

When Should A/B Testing Be Used?

The method is especially useful for existing products with sufficient traffic and clearly defined optimisation goals.

For example, for conversion optimisation, UX improvements, or product development.
