Feng-GUI: Mr. Reggelin, you often mention that many websites fail to reach their full potential. What exactly is going wrong, and how do you approach this in your work?
Jonas Reggelin: I see tremendous untapped potential in many websites. Too often, the focus is solely on visual aesthetics or technical functionality, while the psychological mechanisms driving user behavior are completely overlooked. This is a critical mistake, as 95% of our decisions are made unconsciously. Neuro Web Design addresses this gap by analyzing and optimizing websites to not only look appealing but also activate the right subconscious triggers in users.
Feng-GUI: An important part of your work involves predictive eye-tracking. Why is this technology so crucial in neuro web design?
Jonas Reggelin: Predictive eye tracking is a game changer. It allows us to precisely simulate how users perceive a website and where their gaze will naturally fall—even during the design phase. Thanks to providers like Feng-GUI, we can generate data in a matter of minutes that traditionally required costly and time-consuming physical eye-tracking studies. This technology boasts remarkable accuracy—up to 92% compared to real-world eye-tracking data.
What makes it so valuable is that we can identify whether key elements like call-to-action buttons or product information are optimally positioned before the site even launches. This saves both time and resources, as we can address potential weaknesses early on. For us, predictive eye-tracking is an indispensable tool because it provides the foundation for data-driven decisions, significantly enhancing optimization efficiency.
Feng-GUI: Can you provide an example of how predictive eye-tracking has directly improved a website's performance?
Jonas Reggelin: Absolutely. We worked with a client whose product detail pages were well-designed but underperforming in conversions. By using Feng-GUI's eye-tracking analysis, we discovered that users' attention wasn't naturally drawn to key elements like the purchase button and price display.
After making targeted adjustments based on the analysis, we saw a significant shift in user focus. Within just one month, the conversion rate increased by over 35%. This demonstrates how even minor, data-driven changes can lead to substantial results.
Feng-GUI: Some critics perceive such technologies as manipulative. How do you respond to these concerns?
Jonas Reggelin: That's a valid concern, but I believe it requires a nuanced perspective. The goal isn't manipulation—it's about creating an intuitive and enjoyable user experience. Websites designed with scientific insights help users navigate more easily and find what they're looking for faster.
As a member of the Neuromarketing Science & Business Association, I adhere to a strict ethical code. Our mission is to use technology and psychology responsibly to improve user experiences—not to deceive. Predictive eye-tracking tools, like those from Feng-GUI, empower us to achieve this vision effectively.
Feng-GUI: You've mentioned that many companies still rely on traditional metrics like time on site or bounce rate. Why do you consider these metrics problematic?
Jonas Reggelin: These metrics can often be misleading. For example, a long time on site might suggest user interest—or it could indicate frustration as users struggle to find what they're looking for. Predictive eye-tracking goes much deeper, showing us whether users are smoothly guided through the site or encounter obstacles that disrupt their journey.
Instead of relying solely on numbers, analyzing gaze patterns and visual focus allows us to make precise, targeted adjustments. This is the difference between a website that's merely functional and one that truly delights users while driving revenue.
Feng-GUI: Your book Neuro Webdesign is a bestseller. Why do you think it has resonated so strongly with readers?
Jonas Reggelin: I believe the book's success lies in its ability to address a key need among website owners: actionable, easy-to-implement strategies to understand and engage users more effectively. It draws on over 200 studies and my extensive professional experience, but instead of being heavy on theory, it provides practical approaches that anyone can apply—whether for small tweaks or major overhauls.
Many readers have told me they've seen significant improvements by implementing just a few of the book's insights. It shows that effective web design doesn't have to be expensive or overly complex—you just need to know which psychological levers to pull.
Feng-GUI: What advice would you give to businesses that are not achieving the desired results with their website?
Jonas Reggelin: The first step is asking the right questions: Where are users looking? What's distracting them? And most importantly, why are they behaving the way they are? Predictive eye-tracking provides precise answers to these questions and is an investment that pays for itself many times over. With the right data, such as that provided by Feng-GUI, even small adjustments can have a profound impact.
Thank you for the insightful conversation!

GERMAN VERSION
Feng-GUI: Mr. Reggelin, you often mention that many websites do not reach their full potential. What exactly goes wrong and how do you deal with it in your work?
Jonas Reggelin: I see enormous untapped potential on many websites. Too often, the focus is solely on visual aesthetics or technical functionality, while the psychological mechanisms that control user behavior are completely overlooked. This is a crucial mistake, because we make 95% of our decisions unconsciously. Neuro web design closes this gap by not only making websites visually appealing, but also specifically activating the right unconscious triggers in users.
Feng-GUI: An important part of your work is predictive eye tracking. Why is this technology so crucial in neuro web design?
Jonas Reggelin: Predictive eye tracking is a game changer. It allows us to accurately simulate how users perceive a website and where their gaze naturally falls - even in the design phase. Thanks to providers like Feng-GUI, we can generate data within minutes that previously required complex and expensive physical eye tracking studies. This technology achieves impressive accuracy - up to 92% compared to real eye tracking.
Its value lies in the fact that we can recognize early on whether key elements such as call-to-action buttons or product information are optimally placed, even before the page goes live. This saves time and resources because we can fix weak points early on. For us, predictive eye tracking is an indispensable tool because it forms the basis for data-based decisions and significantly increases the efficiency of optimization.
Feng-GUI: Can you give an example of how predictive eye tracking has directly improved the performance of a website?
Jonas Reggelin: Absolutely. We worked with a client whose product detail pages were well designed but had disappointing conversion rates. Feng-GUI's eye-tracking analysis showed that users' attention was not naturally drawn to important elements such as the buy button or the price information.
After making targeted adjustments based on the analysis results, we were able to significantly improve the user experience. Within a month, the conversion rate increased by over 35%. This shows how even small, data-based changes can have a huge impact.
Feng-GUI: Some critics see such technologies as manipulative. How do you respond to these concerns?
Jonas Reggelin: This concern is justified, but I think it requires a more nuanced approach. The goal is not manipulation, but an intuitive and pleasant user experience. Websites that are optimized with scientific findings help users to find their way around more easily and discover what they are looking for more quickly.
As a member of the Neuromarketing Science & Business Association, I adhere to a strict code of ethics. Our mission is to use technology and psychology responsibly to improve the user experience - not to deceive. Tools like Feng-GUI's predictive eye tracking help us do just that effectively.
Feng-GUI: You mentioned that many companies still rely on traditional metrics such as dwell time or bounce rate. Why do you think these metrics are problematic?
Jonas Reggelin: These metrics are often misleading. A long dwell time can, for example, signal interest – or frustration because users cannot find what they are looking for. Predictive eye tracking goes much deeper: It shows us whether users move smoothly through the page or whether they stall at certain points.
Rather than relying on numbers alone, analyzing eye movements and visual focus allows us to make targeted and precise adjustments. That's the difference between a website that just works and one that delights users while driving sales.
Feng-GUI: Your book Neuro Webdesign is a bestseller. Why do you think it inspires so many readers?
Jonas Reggelin: I believe the success of the book lies in the fact that it addresses a central challenge for website operators: How can I better understand users and address them in a targeted manner? It offers concrete, easy-to-implement strategies based on over 200 scientific studies and my many years of experience.
Instead of theoretical treatises, it contains practical methods that anyone - from freelancers to large companies - can use directly. Many readers report that they have achieved significant improvements with just a few adjustments. Good web design doesn't have to be expensive or complicated - you just have to know which psychological adjustments to make.
Feng-GUI: What advice do you have for companies that are not getting the results they want from their website?
Jonas Reggelin: The first step is to ask yourself the right questions: Where are users looking? What distracts them? And above all – why do they behave the way they do? Predictive eye tracking provides precise answers and is an investment that pays off many times over.
With the right data – like that from Feng-GUI – even small optimizations can have a huge impact.
Thank you for the exciting conversation!
