Progress Bars (GT#4)

Show a meter of meaningful steps toward a Win-State, so the visible gap nudges users to finish. Chou's anchor case is LinkedIn's profile-completeness bar, which lifted completion after an easier interface on its own had not.

Plain label: visible completion meterAlso known as: Progress Bars, completion meter, setup checklist

How it works

People dislike visible incompleteness, so a bar at 70% pulls them toward 100% (CD2). The bar adds wanting where usability work only added ease: Chou's point is that making a task easy is not the same as making people want to do it. Each segment should be a step that helps the user, and the bar must be able to reach the end. Goal-gradient and endowed-progress research outside the book points the same way.

Evidence warning

LinkedIn never published controlled data on the bar's effect; the 20% figure circulates without a primary source, so treat it as an anecdote and test your own bar against a holdout.

What the research says

LinkedIn's profile-completeness bar reportedly raised profile completion by about 20% for little engineering effort, after costlier efforts toward the same goal had stalled.

How to build it

Web: A 'store 60% ready' meter where each segment names its benefit and links straight to the next missing step.
B2B: A 'setup 4 of 6' checklist on the home screen that disappears once complete.
Mobile: A profile-strength meter that starts with credit for the steps already done at sign-up.

What can go wrong

A bar that can never reach 100%.
Steps added to keep users busy or to collect data that doesn't help them.
Segments that are clicks rather than meaningful actions.

Pairs well with

Credit the real steps already taken (endowed progress, F10).
Break long journeys into milestones so the next one always feels close.

LinkedIn: the profile strength meter
No public controlled data on the meter's effect on profile completion; the percentages that circulate online are unsourced and should not be cited. In Feb 2012 LinkedIn reweighted completeness toward fields members control, such as Skills (LinkedIn blog).

TechniqueEvidence grade B. Moderate evidence: solid studies with some limits.
Endowed progress that credits real steps
a head start you actually earned
Start new users partway along a setup checklist by crediting things they have really done (account created, email confirmed), show the single next step, and make each step deliver value to the user, not just data to the company.
TechniqueEvidence grade B. Moderate evidence: solid studies with some limits.
A commitment ladder that starts with a tiny yes
small first step, then bigger
Design a sequence where the first rung is something almost everyone accepts and each next rung asks a little more, with real value at every step: pick a topic, then set a weekly digest, then share it with the team.
TechniqueEvidence grade C. Limited evidence: few or small studies.
Reassurance window after commitment
fast first value after sign-up or purchase
Right after someone signs up or buys, confirm what they now have and get them to a first quick win in the same session ("Your workspace is set up; bring in your first file now."). Confidence peaks just after a decision, and that window is the best moment to turn it into use.
TechniqueEvidence grade B. Moderate evidence: solid studies with some limits.
Foot-in-the-door ladder with the endpoint visible
small first step, larger steps later
Begin with a first step nearly everyone accepts (a free calculator, saving a result), then offer larger related steps: a profile, a first project, inviting a teammate, a trial, a plan. Each rung should deliver value on its own, stopping should cost nothing, and the endpoint (price, renewal, data) should be visible from the first rung.
TechniqueEvidence grade B. Moderate evidence: solid studies with some limits.
User-written goal, shown back
goal in the user's own words
Ask users to write, in one sentence, what they want to achieve, then show it back at useful moments: on low-motivation days, at the next milestone. Writing makes the commitment active and gives users a record of their own intent; when the goal is reached, prompt the next one.
TechniqueEvidence grade B. Moderate evidence: solid studies with some limits.
Level-matched peers for newcomers
beginners see beginners
Show beginners what other beginners did, not only polished expert work: "Learners in week 1 completed 3 lessons", galleries of first projects, a buddy one step ahead in the same segment. A peer at your own level makes the first action feel doable.
