Crowdsourcing is not limited to online activity, however, and there are various historical examples of crowdsourcing. Contemporary crowdsourcing often involves digital platforms to attract and divide work between participants to achieve a cumulative result. Below you can see what the app looked like prior to the update and then after Duolingo integrated AdMob’s native ads solution.This graphic symbolizes the use of ideas from a wide range of individuals, as used in crowdsourcing.Ĭrowdsourcing involves a large group of dispersed participants contributing or producing goods or services-including ideas, votes, micro-tasks, and finances-for payment or as volunteers. So to ensure the best user experience, Duolingo chose to use AdMob native ads - a format that allows fully customized ads to be placed in ways that don’t disrupt their student’s learning flow. However, if implemented poorly they can be intrusive, poorly designed, erode trust and result in a bad user experience. When implemented properly ads can have a transformational effect on a business's ability to grow. Thus, Duolingo faced a profound challenge - how could they monetize a free, beloved product without undermining their mission or hurting the trust of their users.ĭuolingo saw ads as a way to build a sustainable business while still placing product value as the most important feature. It was selected by Apple as iPhone App of the Year in 2013, and by Google as Best of the Best for Android in 20.īuilding, supporting, and expanding on a platform used by that many people can be expensive and complex.

Duolingo is an online education platform that helps millions of people around the world learn languages and also one of the most popular educational apps globally.
