Abstract
The aim of this article is to analyze the evolution of digital electoral advertising in Brazil, from a historical and politically mature perspective, focusing mainly on the transparency of boosted advertising, through an analysis of the main tools used for this purpose. We argue that the possible improvement of transparency in digital electoral advertising should be based on the need to facilitate and increase the verifiability, by the public, of the regularity of the application of resources in the campaign, and of the methods of segmentation of sponsored content.
