Search and Discovery

Kahoot

Product Design
Making 100 million games available worldwide

Since Kahoot!’s release in 2013, over 100 million games have been created on the platform. This vast library of games provides an amazing resource to teachers looking for rich learning content. However the platforms Search & Discovery section had changed little since the launch. With limited time and resources our challenge was to improve the search experience and increase the number of games played via search.

Goal: Increase number of games played via search.

The new search and discovery sections of Kahoot!
Audience

For this challenge, we wanted to optimise search around the needs of teachers but to do so we needed to understand two key personas:

Adopters: These teachers regularly searched the platform for games they could duplicate or modify for use in class. They needed to identify and verify the quality and accuracy of content quickly, so they could use their time to plan other aspects of their lessons.

Creators: These teachers invested time in creating high quality learning content. Ambitious and community minded, these teachers shared content to benefit their peers and boost their teaching profiles. For these teachers, we needed to elevate their content and make it visible to all.

Design Process

We started by conducting an in-depth research project to understand the challenge:

User Interviews

Had interviews with existing teacher users about the problems and challenges they faced when  searching for Kahoot!'s to play.

Competitor Analysis

We conducted a detailed analysis of competitors UX / UI search patterns to find best practice methods and techniques we could utilise.

Data Analysis

We created a series of questions about search’s current performance which we investigated through our data tools.

Workshops

This research formed the basis of a 2 day in-person workshop. As a team we shared our learnings, analysed the data and proposed different solutions to improve search and discovery.

Shared learnings from research
Refining solutions down to a single approach
Creating a vision

After the session we refined these solutions into a single approach which we shared as a lo-fidelity clickable prototype. This prototype offered the business a clear, mid-long term vision of what we hoped to achieve and provided an artefact for future teams to build from.

Core aspects of our search vision
Speccing out experiments

Based on the vision and time we had allocated to the project, we decided to run 7 A/B experiments where we felt we could have the highest impact. These experiments included testing out an updated search item, adding a ‘preview before play’ on games and creating an opportunity for a new, browsable search landing page.

THESE ARE SOME OF THEY'RE LOCATIONS
'Quick Look' was a key feature in helping teachers identify good content quickly
Impact

The impact of the experiments was as follow:

  • The new new search list item UI led to greater game engagement. This included a 132% increase in shares and 15% increase in game duplication.
  • Introducing Quick look led to an increase the amount of content viewed, decreased 'preview plays' (games played with <1 player) and increased the game completion rate.
  • Creating the vision prototype set in motion the next initiative to build out a full version of the Discover homepage.
