Purpose: The young members of Generation Z, who are hyperconnected and addicted to social media, are thought to be particularly sensitive to environmental and social concerns. This study aims to draw on a conceptual model that is based on the stimulus-organism-response paradigm. Exposure to sustainability content on social media is considered to be a stimulus that affects the development of sustainability advocacy among GenZers, who modify their lifestyles. Five hypotheses are developed and tested. The goal is to define the antecedents of sustainability advocacy.Design/methodology/approach: A Web survey was distributed to 660 Italian members from Generation Z (aged between 14 and 25) to detect the frequencies of exposure to sustainability content on social media, sustainable habits, sustainable consumption behaviours and actions that are related to sustainability advocacy on social media. Correlation and multiple regression analyses were conducted to investigate the relationships between these factors.Findings: The results show that exposure to sustainability content on social media affects both sustainable habits and sustainable consumption behaviour. These three factors influence the propensity to promote sustainability-related issues on social media and should, therefore, be considered to be antecedents of sustainability advocacy.Practical implications: The study, which takes the social responsibilities of large companies into account, is conducive to understanding how brands can intervene in the soliciting processes of sustainability advocacy through social media to gain legitimacy and increase brand awareness.Originality/value: This study is among the first to consider the use of social media for advocating sustainability among Generation Z, thus enriching academic research on this cohort.

Purpose: The study aims to investigate the usage of diversity and inclusion (D&I) signals in communications for employer branding through digital channels made by European companies.Design/methodology/approach: A quali-quantitative content analysis approach was employed to detect the usage of D&I signals of the top 43 European companies ranked in the 2021 Refinitiv Diversity and Inclusion index. These signals were organized according to Plummer's Big 8 diversity's dimensions. A correlation analysis was conducted to verify a relationship between D&I initiatives and digital communication for employer branding on corporate websites and LinkedIn. Descriptive statistics were used to analyze the D&I dimensions' pervasiveness in digital communications and relevance on LinkedIn.Findings: The results show that the correlation exists only between D&I initiatives and communication on the corporate website, while LinkedIn is still underused in this field. The most pervasive and relevant D&I dimensions for European companies are “Gender” and “Sexual Orientation”.Originality/value: This paper enriches employer branding research by providing original insights into the use of D&I dimensions in digital communications.

Purpose: The objective of this paper is to propose a taxonomy of sustainability communication (SC) topics that provide digital content managers with a guide for setting a sustainability content agenda and for fostering stakeholder engagement mechanisms on environmental, social and economic issues that increasingly characterize conversations on social media of all stakeholder groups.Design/methodology/approach: Taxonomy is a conceptual and qualitative way used to classify and represent the corporate sustainability (CS) domain of knowledge. The taxonomy categories of SC topics are both theoretically and empirically derived, combining an in-depth literature review with a thematic content analysis of 300 web pages of the corporate websites of the top ten sustainable brands selected in “The 2019 GlobeScan-SustainAbility Leaders Survey.”Findings: The analysis of the results led to the construction of a hierarchical dictionary of tags that categorizes all sustainability topics based on a new, four-dimensional conceptual structure: planet, people, profit and governance. Each dimension is organized in four groups of sustainability themes, which, in turn, group multiple topics, considered the smallest communication unit to develop the SC content.Practical implications: The taxonomy provides a concise and immediate conceptual framework on all those topics of broader interest, which, suitably modulated, can act as touch points with several groups of stakeholders. Drawn upon the best practices of thematic organization of SCs via the web, the taxonomy represents a guide for programming an editorial plan based on environmental, social, economic and governance issues from a sustainability content marketing perspective. The taxonomy of sustainability topics also finds application as a framework for a content intelligent system, providing a dictionary of tags that can be used for the indexing and retrieval of SC web content.Originality/value: The study represents the first attempt at reaching a taxonomic organization of the sustainability aspects from a communicational perspective, supporting a new way of thinking and managing SC in the digital realm. Moreover, the results highlight, for the first time, that the Triple Bottom Line (TBL) theory, applied to corporate communications, lacks the governance aspect, which is essential to pursue sustainability consistently and effectively.

Purpose: For companies that intend to respond to the modern conscious consumers' needs, a great competitive advantage is played on the ability to incorporate sustainability messages in marketing communications. The aim of this paper is to address this important priority in the web context, building a semantic algorithm that allows content managers to evaluate the quality of sustainability web contents for search engines, considering the current semantic web development.Design/methodology/approach: Following the Design Science (DS) methodological approach, the study develops the algorithm as an artefact capable of solving a practical problem and improving the operation of content managerial process.Findings: The algorithm considers multiple factors of evaluation, grouped in three parameters: completeness, clarity and consistency. An applicability test of the algorithm was conducted on a sample of web pages of the Google blog on sustainability to highlight the correspondence between the established evaluation factors and those actually used by Google.Practical implications: Studying content marketing for sustainability communication constitutes a new field of research that offers exciting opportunities. Writing sustainability contents in an effective way is a fundamental step to trigger stakeholder engagement mechanisms online. It could be a positive social engineering technique in the hands of marketers to make web users able to pursue sustainable development in their choices.Originality/value: This is the first study that creates a theoretical connection between digital content marketing and sustainability communication focussing, especially, on the aspects of search engine optimization (SEO). The algorithm of “Sustainability-contents SEO” is the first operational software tool, with a regulatory nature, that is able to analyse the web contents, detecting the terms of the sustainability language and measuring the compliance to SEO requirements.
