This paper showcases studies that illustrate the potential of analyzing online job search data and of intervening in the online job search process. It presents the current insights and some open questions and highlights conditions under which some of the recent interventions are likely to improve market outcomes overall, rather than improving only the outcomes for the treated individuals.
