UX/UI Design FAQs
UX (User Experience) design focuses on the user's overall experience when interacting with your digital product or service, aiming for it to be intuitive, efficient, and satisfying. UI (User Interface) design focuses on the visual and interactive part of the interface. A good combination of UX/UI improves user satisfaction, increases the conversion rate, and reduces abandonment, directly impacting business results.
If your users complain about the difficulty of using your website or app, you have a high bounce rate, low conversions, or receive negative feedback about the digital experience, it's time to invest in UX/UI. It is also advisable if you are launching a new digital product or want to differentiate yourself from the competition.
A specialized agency usually offers:
- UX/UI Audit
- User research
- Wireframe and prototype design
- Visual interface design
- Usability testing
- Conversion Rate Optimization (CRO)
- UX/UI consulting and training
The standard process includes:
- Analysis and diagnosis of the current situation
- User research and definition of objectives
- Ideation and design of solutions (wireframes, prototypes)

The cost varies depending on the scope of the project, its complexity, and the agency's experience. It can range from one-off audits (starting from X€) to complete redesigns (several thousand euros). It is advisable to request a personalized quote after an initial diagnostic meeting.
It depends on the size and complexity of the project. An audit can take between x and x weeks, while a complete redesign of a website or app can take from 1 to 6 months. The agency should provide you with a detailed timeline at the beginning.
Companies usually experience:
- Increase in conversion rate
- Higher user satisfaction and loyalty
- Reduction in abandonment rate
- Better search engine ranking (SEO)
- Increase in sales or leads
Some agencies only deliver the designs and documentation, while others offer a comprehensive service that includes technical implementation. It is important to clarify this point before hiring.
Success is measured by clear KPIs:
- Conversion rate

An agency brings multidisciplinary experience, validated processes, access to advanced tools, and the ability to handle larger projects. In addition, it usually offers continuous support and guidance.
