This study examines the role of digital media in civic and political engagement, specifically the respective roles of websites vs. social media in relation to volunteering. The study uses fourcountry (United States, United Kingdom, France, and Canada) survey data collected in 2019 and 2021 (n = 12,359). For both types of volunteering, we find that organizations' websites are more strongly correlated with volunteering compared to following organizations on social media. We replicate this finding across multiple countries, two types of analysis, and volunteering for civic and political organizations. Our findings suggest that the informational role of websites is of greater importance than the creation of quasi-membership ties inherent to social media when it comes to mobilizing volunteers. However, engaging in both online activities has the strongest relationship with volunteering, suggesting a need for multi-method communication strategy. This finding is important with respect to developing communication strategies in civic and political groups.
