Can you get your users to do something simply by asking them to do it? If so – congratulations! You have some awesome users
Most of us aren’t that lucky. As a matter of fact, asking our users to do something, sometimes has the opposite effect!
There is a usability feature called a completeness meter that is employed by companies like Google, LinkedIn, and Box. These types of progress bars inform users of how close they are to completing a set of tasks by showing percentages of completion along the way.
Normally, these are used to encourage new users to add personal information or perform activities to develop a much richer user experience. You can think of a progress bar as missions or levels for a web application.
