We investigate to what degree EU-level and nation-level women’s NGOs in the UK and Germany mobilize constituencies via online means. Utilizing network mapping tools as well as original data from about 100 women’s NGOs on the EU level, in the UK, and Germany, we analyze density and distribution of relationships in these networks as well as their actual usage of interactive communication means as indicators of their capacity to engage publics. We find that the tendencies we observe in the national networks are elevated and reinforced at the EU level. National UK women’s NGOs put much effort in creative and vivid online public engagement, whereas German national organizations are more inclined to static documentation of offline engagement or lobby work. At the EU level, the UK members of the women’s umbrella network (EWL) are even more active than national level UK NGOs and the German EWL members are slightly more passive than the German national women’s network.
