One of the last design sprints that my team hosted was in South Africa. This is where we took companies through best practices for landing page design and asked them to prototype in the afternoon.
One Life, an insurance company in South Africa, attended the sprint. Within one day, they brought their agency along with their in-house team, and they developed a completely new product prototype. It was very different from their original landing page.
As you can see, they implemented a very short and concise form, which allowed them to bring the key call-to-action above the fold. They included the value proposition in two bullet points—very nice and visual. They improved the image layout, fixed the header at the top, and placed the key call-to-actions in the header.
All in all, they mentioned they were well aware of these best practices before but had never gotten around to implementing them. The design sprint allowed everyone to come together and complete this work.
As a result, the new prototype completely outperformed the original. They decided to launch the new landing page about a month after the sprint.
