The fundamentals of UI/UX design
Great design starts with a deep understanding of your users. This involves conducting research, creating detailed personas, and mapping out precise user journeys. These elements help align the interface with real needs, not assumptions. For example, a simplified contact form can reduce bounce rates by 20%, according to studies by the International Journal of Human-Computer Studies.
User research and personas: the foundation of success
Without qualitative and quantitative data, design remains an expensive guessing game. A UX audit helps identify existing friction points and prioritize improvements. At Tylias, we combine user interviews, A/B testing, and behavioral analysis to ensure informed decisions.
Information architecture: guide without distracting
A well-structured website reduces user search time. Intuitive navigation, logical categories, and clear visual hierarchy increase conversion rates. According to the Baymard Institute, a poorly organized e-commerce site can lose up to 50% of its visitors before they even reach the product page.
Prototype to validate before developing
Interactive prototyping is a critical step to avoid costly rework later. Tools like Figma allow us to validate usability and user journeys before development, reducing unnecessary iterations and speeding up time-to-market. For example, a prototype tested with just 5 users can uncover 85% of usability issues, according to the “5-user test” rule.
Why prototyping is an investment, not an expense
By integrating prototyping into the design phase, development teams gain clarity on functional requirements, avoiding technical misunderstandings and focusing on what matters most: the user experience.
Accessibility: a major business criterion
An accessible website (RGAA/WCAG) is not only a legal requirement—it’s a competitive advantage. According to the W3C, 15% of the world’s population lives with a disability. Inclusive design expands your audience and improves SEO, as Google values accessible sites. At Tylias, we train our teams in accessibility from the UI/UX design phase, incorporating appropriate contrasts, semantic tags, and textual alternatives.
UI/UX and conversion rate optimization (CRO)
The link between design and conversion is direct. A poorly placed “Add to cart” button can reduce sales by 15%, according to the Baymard Institute. CRO relies on analyzing micro-interactions, reducing friction, and optimizing calls to action. For example, repositioning a checkout button based on user scroll data can increase click-through rates by 30%.
Continuous iteration: the secret to a design that converts
Design is never static. Trends evolve, behaviors change. An iterative approach, based on regular testing and user feedback, helps maintain high performance. At Tylias, we integrate a design system to ensure visual consistency while facilitating updates.
Why work with an expert agency?
A great UI/UX designer isn’t just about aesthetics—they combine creativity, data, and cognitive psychology. At Tylias, our designers work closely with developers to ensure that both the technical and visual design are optimized. This results in faster, more accessible, and more converting sites. For example, our mobile-first approach has helped clients gain an average of 40% more qualified mobile traffic.
Design for the international market
Design doesn’t stop at borders. A multilingual interface or one adapted to local cultures can multiply opportunities. At Tylias, we integrate localization from the design phase, taking into account cultural specificities and target market expectations.
Conclusion: transform your UX into a growth lever
A well-thought-out UI/UX design doesn’t just beautify a site—it guides users toward action, strengthens credibility, and improves SEO rankings.
