1. Data Analysis
We start with a comprehensive analysis of quantitative data from your website or e-shop (analytical tools, site metrics, heatmaps, session recordings, surveys). Our goal is to identify the exact points where users leave or encounter obstacles. We uncover hidden weaknesses and propose optimization opportunities.
2. UX Audit and Best Practices
We conduct UX audits and use best practices to gain a deeper understanding of user behavior. Our multi-disciplinary team of experts is involved in the process - Web and Data Analyst, UX Designer, Researcher, E-commerce Consultant, Senior Developer, Copywriter, and Customer Experience Specialist - and together we create hypotheses based on our know-how.
3. Working with Real Customers
To get a complete picture, we supplement data from usability testing and focus groups, which provide us with qualitative data. This helps us not only understand but also see how real users behave on your website.
1. Hypothesis Creation
Based on in-depth analysis and collected data, we create specific hypotheses and propose solutions aimed at eliminating the root cause of the problem.
2. Technical Solutions and Design
Subsequently, we prepare technical solutions and design an intuitive UX design, aiming to remove obstacles in the user experience and facilitate the path to conversion.
1. A/B and Multivariate Testing
We systematically test technical solutions and UX design proposals in various versions of elements or entire pages. Based on data, we determine which version achieves better results and implement changes with demonstrably higher conversion rates.
2. Pre-launch Tests and Coordinated Tests
Before implementing any changes, we conduct pre-launch tests to ensure smooth implementation and fine-tune technical details. At the same time, we coordinate tests for maximum accuracy and efficiency.
3. Usability Testing
By testing with real users in our UX lab, we gain valuable insights into their behavior and experiences. This helps us see how they react to changes and perceive them, and possibly remove any remaining obstacles.
4. Focus Groups
To gain a deeper understanding of customers' opinions, attitudes, and motivations, we organize focus groups that provide us with detailed qualitative data.
Designing an Evaluation Methodology
We propose an evaluation methodology that focuses on measurable outcomes. Based on data, we determine which changes have achieved better results and what their impact is on your business goals.
CRO Framework
Our conversion rate optimization (CRO) process is systematic and data-driven to transform your website into an effective customer acquisition tool. At ui42, we employ a comprehensive holistic approach to maximize growth.
Advantages of the CRO approach at ui42
Multidisciplinary team under one roof
Analyst, UX researcher, copywriter, designer, developer, e-commerce consultant - all in one team. No ping-pong between three agencies. When the heatmap shows a problem in the checkout, within 48 hours we have a hypothesis, copy, mockup, and dev estimate. One project, one calendar, one responsibility.
Custom UX laboratory
We test with real users, not just through Hotjar. We have our own UX laboratory where we conduct moderated user tests, eye-tracking, and in-depth interviews. Quantitative data (GA4, heatmaps, A/B tests) will tell you WHAT is happening. Qualitative research tells you WHY. Without one of these, you are optimizing blindly.
20+ years on the market, 200+ e-shops
We are not seeing your problem for the first time. In 20 years in digital, we have optimized over 200 e-shops and B2B websites from small DTC brands to international retail networks. Pattern recognition, you receive from the first audit.
The entire digital stack, not just CRO
CRO is not an isolated project and works best when aligned with acquisition. We do performance marketing (Google Ads, Meta, SEO), analytics (GA4, Matomo), UX, and development. When we see in a CRO audit that the problem lies in the quality of traffic from Meta campaigns, we don't need to send it to another agency, we implement it in parallel.
Buxus CMS - our own product
We implement changes directly, without waiting for an external developer. If you are on Buxus, we deploy CRO changes immediately, from hypothesis to live A/B test in days, not weeks. And when you need custom functionality for an experiment (personalization, dynamic offers, new checkout flow), we build it without relying on a third-party supplier.
Decision-making based on data
Every change on your website has a hypothesis and a success metric. We don't say "we think it would help to change the button." We say: "Hypothesis X, we measure metric Y, the test will be statistically significant with sample Z, we will decide within 14 days." No gut decisions.
What is the output of CRO?
Intuitive design and UX
We ensure that your website is not only visually appealing but above all functional and intuitive. We optimize navigation, page loading speed, and ensure seamless mobile responsiveness, which is essential for today's traffic.
Understandable and accessible content
The result is content that is clear, engaging, and understandable for every user, including people with disabilities. It also includes compelling calls to action (CTAs) that effectively guide visitors towards the desired conversion.
Building Trust and Social Proof
By integrating references, case studies, evaluations, client logos, and security certificates, we strategically build the credibility of your brand.
Psychology of Conversion
We leverage deep knowledge of consumer psychology and cognitive biases (such as fear of missing out FOMO, social proof, authority, reciprocity) to design highly persuasive experiences. We motivate users to take action and support their decision-making.
A/B and Multivariate Testing
We systematically test different versions of elements and entire pages to identify the most effective solutions. Based on data, we determine what actually works and implement changes with demonstrably higher conversion rates.
Fine-tuned technical deficiencies
We will eliminate technical issues that hinder a smooth user experience. This includes fixing bugs that slow down page loading, removing broken links or forms, and ensuring seamless website functionality on all devices.

FAQ / Frequently Asked Questions about CRO
Conversion Rate Optimization (CRO) is a systematic process aimed at increasing the percentage of visitors to your website who perform a desired action – known as a conversion. It doesn't matter whether it's purchasing a product in an e-shop, filling out a contact form on a company page, registering for an event, downloading an e-book, subscribing to a newsletter, or any other specific business or marketing goal. In practice, this means that from existing traffic you gain more valuable actions, thereby maximizing the return on investment in your website without the need for additional costs to acquire new traffic. Our approach at ui42 focuses on in-depth analysis of user behavior and eliminating obstacles on their path to conversion.
If your website generates traffic but does not achieve the expected results in meeting set goals (e.g., few inquiries, low sales, weak engagement), then CRO is the ideal solution for you. Common signs of needing CRO include a high bounce rate, a low number of completed target actions, or if you are unsure why visitors leave your site without converting. Thanks to our CRO/UX Auditing, we can accurately identify weak spots and propose specific, data-driven steps to improve performance.
The main advantages of CRO are primarily the increase in the number of conversions and revenue from existing traffic, a significant improvement in return on investment (ROI) – often 2-5 times the original investment, and a deeper understanding of the behavior of your online customers/visitors. It also leads to an improvement in user experience (UX) on your site and a reduction in acquisition costs (whether customers or leads). Results vary depending on the complexity of the website and the scope of changes, but thanks to data-driven decisions and systematic A/B and multivariate testing, we can effectively implement changes and monitor their impact within a few weeks to months.
While SEO (Search Engine Optimization) and online advertising (e.g., PPC campaigns) primarily focus on acquiring new traffic to your website, CRO focuses on how to get the most conversions from this existing traffic. CRO, SEO, and online advertising complement each other and form a comprehensive digital strategy. Quality content and optimized user experience (UX), which CRO focuses on, also positively influence search engine rankings (SEO) and the effectiveness of your advertising campaigns, thus ensuring higher overall performance of your online business.
Our comprehensive approach includes various methods and tools for thorough analysis and optimization. We start with data analysis from various sources (Google Analytics, Hotjar, Clarity, internal CRM systems, etc.), which help us identify critical points and user behavior. Subsequently, we use CRO/UX Auditing, user testing, heatmaps, session recordings, and A/B and multivariate testing to validate changes. We also focus on applying insights from conversion psychology, content optimization, and effective calls to action (CTA), as well as building trust and social proof on your website. All decisions are based on data and real test results, ensuring measurable improvement.
Yes, CRO is relevant and beneficial for websites of all sizes and types. Even smaller, targeted changes based on data can bring surprisingly large improvements in conversion rates and achieving your business goals. Our aim is to identify the biggest opportunities for growth and optimize investments to achieve the highest possible return on investment (ROI). For smaller projects, we often focus on the most critical points with the greatest potential for quick and visible improvement, ensuring efficient use of the budget.
