Goals

The TravelBird team in Germany was getting feedback and requests from users who wanted a way to browse travel deals near them. Specifically, users wanted offers for places they could travel to by car within a few hours. By designing this feature for the German market, we hoped to increase the number of daily bookings.

Strategy and approach

Defined UX/UI design requirements

I mapped out the scope with the Head of Design and Product Owner. The requirements were: pragmatic design to ship without additional back-end efforts, responsive web design so pages render well on different devices and screen sizes, a page for search and results, and clear entry points on the homepage and search bar.

Localized UI to German preferences

I considered different ways to design the search results user interface. For example, showing places you can drive to within 2 or 3 hours. But German users are very precise. They prefer to know the number of kilometers. They are also sensitive to privacy and sharing personal information.

With all this in mind, I designed the interface with 3 radio buttons to search within 300 km, 500 km or 700 km – the most common travel distances. I decided not to automatically populate the user’s location or require this data to perform a search.

Explored several map design options

A ‘nearby’ concept is not easy to visualize. So I created wireframes to explore and compare multiple design options. For example, we could present the map as a circle, donut, or filled circle.

We debated features and functionality. Should the search results include the user’s city? How interactive should the map be?

This was a tough decision, but in the end we went with a simple visualization to ensure ease of use. I used a flat design style for the map, with a radius and pins to represent points of interest. Next to the map, I placed photos of German cities to help users connect with areas of interest.

Strategic use of color

Color plays an important role in UX/UI design. A consistent color scheme builds trust and familiarity. Furthermore, use of specific colors for specific content types gives each color a meaning.

TravelBird had three colors in their logo. I reserved the TravelBird yellow for call-to-action buttons, the blue for search box elements, and the orange for deal labels. In this way, users learned to associate orange with travel deals.

Saw a 10% increase in conversion rates, which amounted to approximately 65,000 euros in revenue in the first two weeks.
