Optimizing Recruitment for Qualitative Research: A Comparison of Social Media, Emails, and Offline Methods

Participant recruitment through social media platforms has been suggested as an effective method for sampling from specific populations; however, recent online recruitment attempts have been met with varying levels of success. In the current study, we targeted a specific social media population: those who advocate for the Black Lives Matter movement, delineating between those with high and with low follower counts on Twitter. We compared the outcomes of our recruitment methods, which include Facebook ads; unpaid, personalized tweets; emails to groups involved in community advocacy; and offline methods. Included in our analysis is the amount of effort involved in each recruitment method, as well as advertising costs. Based on our comparison, Facebook advertising was the most effective form of social media recruitment for our study. In contrast, unpaid, personalized tweets were time consuming and ineffective.
