Abstract—This paper reports aspects of social advertisements,
that are part of a rich discursive genre evidenced by their increasingly common exposure on social media and require the use of varied semiotic resources to be fully understood. It sought to investigate how persuasion is employed in government social advertising about dengue fever on a social media outlet. To achieve this goal, this study investigates an evaluation between images and words in the persuasive process in the construction of meaning using Visual Design Grammar and Systemic-Functional linguistics. Through an analysis of data collected from three social advertisements, the results were: in terms of ideational metafunction, the most used transitivity process was the material process; persuasion via seduction and persuasion via conviction were used in the corpora.
 
Keywords—metafunction, persuasion, systemic-functional linguistics, social advertisement
