This paper explores third-party services and trackers used on job search websites. We analyze what kind of data on the job search process is sent to these third parties and whether users have a fair possibility to understand what kind of data collection is taking place on the studied websites. Our results show that 87.5% of the studied websites leak data on the user's actions, such as displayed job advertisements, search terms and the intent to apply for a specific position. One job search website could leak data to as many as 9 third parties. Websites run by public sector bodies had significantly less third parties and data leaks, however. While some third parties may be necessary for targeted advertising, it would be important for website maintainers to consider the number of third parties and better inform users about the data protection activities.
