### Determining Lead Pages  
In SNA, the vertices with the highest centrality of intermediation have the most leadership as they control the communication flows. This fact is illustrated in Table 5, where the five leading pages in the networks of the two organizations analyzed are shown.  
As shown in Table 5, RCC and Spanish Caritas are the leading pages in their respective networks, which means that many nodes need to go through these actors to make indirect connections via the shortest paths. Another page worth highlighting is Flag Day, one of the Red Cross Cadiz's most popular means of raising funds to help children. If the organizations in Table 5 are evaluated in terms of leadership, activity, and popularity, the ranking in Figure 6 is obtained.  
According to the results shown in Figure 6, the Spanish Red Cross is the most popular page; however, RCC holds the leadership, controlling the communication in the network, and it is also the most active. In the case of CAJ's Facebook network, it is the most active organization, but it does not receive much support from the rest of the organizations in its

network, nor is it the leader, which is Spanish Caritas. This last NGDO is also the most popular, despite not being the most active. The most interesting organization is Spanish Caritas, followed by RCC and Spanish Red Cross. CAJ is in the fifth position.  
To understand better how organizations position themselves concerning each of these three parameters, the three-dimensional graph in Figure 7 was developed using the RStudio program and the Scatterplot3d package to show leadership, activity, and popularity.  
Figure 7 shows that the best-positioned organization in its Facebook network is Spanish Caritas, followed by RCC and the Spanish Red Cross. The second group is formed by Caritas Deutschland (7) and Caritas International (8), which are very popular (score 9 in Figure 6), although they had meager leadership and activity scores. The third is formed by CAJ (4) and Caritas Bizkaia (5), which are characterized by being more active than popular but had an intermediate leadership score. The fourth group is made up of Caritas Lebanon (6), Caritas Granada (9), Caritas Cordoba (12), Caritas Aragon (10), and Flag Day (11), which had average scores for activity and popularity, and low scores for leadership. In summary, four groups can be distinguished: The first group is made up of the organizations with the best ratings on leadership, activity, and popularity; the second group is characterized by high popularity (under leadership and activity); the third group stands out for its activity (under leadership and popularity), and the fourth group stands out for its low leadership scores and average ratings in popularity and activity.
