Leaderboards (GT#3)

Rank users on criteria tied to the Desired Action, but in a form where most people can still win: neighbors just above and below, team boards, boards that reset weekly, or boards limited to friends or a similar cohort. Always show the action that moves the user up.

Plain label: near-peer rankingsAlso known as: Leaderboards, leagues, rankings

How it works

Ranking taps accomplishment (CD2) and, in team or friend versions, social influence (CD5). The design target is Urgent Optimism, the sense that a better spot is reachable and worth acting on now. A newcomer facing an all-time global board sees an impossible gap and disengages, which works against the Desired Action. Relative, group, refreshing and small-cohort boards keep the gap small enough to chase.

Evidence warning

Public rankings of employees can hurt morale and invite metric gaming; use opt-in and team views at work.

What the research says

  • Duolingo reported that its weekly leagues increased learning time by about 17% (company-reported, outside the book).

    CASE-M01 in the modern case file (case grade B)

Before you start

  • Enough active users at similar levels to fill near-peer boards
  • The value event is tracked.

How to build it

Mobile
Weekly leagues of about 30 users at similar levels that reset every Monday, with promotion and relegation.
B2B
Team boards in a sales or support tool showing team totals and the next action that adds to them.
Web
A relative view ('#47, 12 points behind Ana') instead of the global top 100.

What can go wrong

  • Global all-time boards that turn most users into losers.
  • Ranking a metric that is easy to game.
  • Boards bolted onto a dull task, which feel insulting.
  • Competition in learning, creative or close-team settings where it backfires.
  • Too few active users, so the board looks empty.

Pairs well with

  • Show the move-up action next to the rank.
  • Where competition does not fit, use a non-ranked spotlight of top members (AG p.485).

    Duolingo: weekly leagues

    Leaderboards raised overall learning time 17% and tripled highly engaged learners (1h+ a day, 5 days a week), per Duolingo's Jorge Mazal (Feb 2023). Company-reported, and part of a broader retention push that grew DAU 4.5x over four years.
