## 2 Materials and Methods  
To achieve the objectives outlined in this study, a mixed-methodology approach based on both the quantitative and qualitative content analysis of various websites was employed. Specific analysis templates were used to collect relevant information about the study subject in each case. The suitability of this methodology is supported by its use in previous research on the evaluation of website interactivity [28], adapted to the type of organization under consideration. Additionally, the organizations' social media profiles were inspected to assess their presence on these platforms. A classification was conducted based on the level of commitment and interaction that social organizations provide to visitors of their websites, with the aim of categorizing the communication tools used by each organization. To execute this, 12 typologies of unidirectional information tools directed towards the public were identified, and, on the other hand, 20 tools aimed at promoting interaction and dialogue with internet users were identified. To systematize the categories of communicative elements present on websites, the resources used by NGOs to present and disseminate information were investigated. Unidirectional (monological) tools were identified (see Table 1), which were characteristic of informative and linear structures, requiring minimal participation or involvement from the receiving audience. In this type of communication, the flow of information is directed in one direction, and the NGO, rather than the website user, has almost complete control over the established communication. The main objective is to establish a connection with the web visitor but only to showcase, disseminate, or broadcast institutional information and keep internet users informed. The level of user participation on websites is very limited, and the communication flow passes from NGOs to users, who cannot send or modify any information on the website, implying a lack of feedback. The following three categories were identified:  
1. Expository--encompassing resources that favor the dissemination of information to a primarily passive and receptive user. This category includes text, graphic, and audiovisual tools. 2. Hypertextual--referring to the use of links that redirect to other websites, allowing for greater interaction than expository resources. This facilitates the active search for additional information and contributes to the investigation of topics related to an organization. 3. Participative--including tools that encourage more active interaction from the internet user compared to the previous categories. These resources are aimed at more active and participatory web visitors and include interactive elements (graphics and infographics) and participatory resources (buttons to follow an account on social media), allowing the user to enhance their interaction with the site's content and show greater interest in an organization. On the other hand, the classification of resources used by NGOs on their websites to interact and engage with web visitors was carried out, identifying bidirectional (dialogical) tools (see Table 2). These tools are based on both asymmetric and symmetric bidirectional communication structures, allowing for increased interaction and dialogue with various possibilities for information exchange, discussion, and collaboration--fundamental characteristics of dialogue. The following categories are presented based on the degree of involvement and participation provided or sought for the web visitor:  
1. Connect: This category encompasses tools that simply request information from the user, showing a very low level of interaction and involvement. 2. Share: This category includes tools that enable users to distribute and share information from the NGO, as well as follow the content that interests them, customizing tracking options. These tools facilitate mild involvement and participation on the part of a website's public users. 3.
