began to get used to these communication tools, which made the speed of purchase decisions
to become faster. In 1989, the Brazilian internet began to be implemented as a communication
infrastructure for academic purposes. The backbone of the network, which received the name
of National Research Network (NRN), was complemented by state networks, funded with
resources from state research support foundations. The network grew rapidly: in 1996, it
already had 7,500 domains; in 2000, 170 thousand; in 2006, one million; and in 2014, three
and a half million (Lins, 2013).
E-commerce – the sale of products in retail with the use of computer networks –
originated, according to Lins (2013), in Europe in 1981; the internet and the improvement of
encryption also allowed confidential information, such as credit card numbers, to be sent in a
more secure way at the time of online purchase. The internet is linked to people's personal and
professional lives and, with this, according to Bulhões (2021), the amount of hours that
Brazilians spend on applications and social media to work from home has practically doubled
as a result of the COVID-19 pandemic.
According to the Insper website (Mundo..., 2022), based on the study Digital 2022:
Global Overview Report published by the Datareportal website, the world is approaching the
mark of 5 billion internet users, which corresponds to 63% of the population. The study also
says that Brazil is one of the countries where people spend most time on the internet, on average
10 hours and 19 minutes a day. The rapid advancement of this technology can be considered a
great growth factor for organizations, so that they can expose their products faster and reach
their customers also faster.
Social media
It was in the 1990s, with the internet available, that the idea of social media also
migrated to the virtual world. Social media are part of the modern world, which encompasses
several tools, whose objective is to empower people to publish their content (Marques, 2018).
According to Marteleto (2001, p. 72), social media represent “a set of autonomous participants,
uniting ideas and resources around shared values and interests”.
According to Goossen (2009), the adaptation of social media in the world of
information technology has generated many important changes for society, providing
knowledge and information in a more practical, faster, and more far-reaching way, serving
various levels of the electronic market.
The spread of social media around the world is considered the greatest technological
revolution that society has witnessed in this millennium (Shih, 2010 apud Crespo et al., 2014).
In the new digital world, a company not having a social media presence is almost unthinkable.
Being in social media, such as Facebook and Instagram, according to Safko et al. (2010),
enables organizations to establish a relationship of trust that influences their users. Also
according to the authors, for a brand, developing and cultivating a profile on social media can
be the chance to win the customer and, subsequently, lead to an improvement in its marketing
results. According to Crespo et al. (2014), when a brand manages to establish a level of
integration between users of social media, with credibility, high reputation, and
recommendation of use of its products, it is more likely to create and expand an affective
involvement of social media users with its products.
In the same sense, for Gouveia (2018), “social media are one of the most powerful tools
of marketing,” because by them one can know customers and potential customers in a simpler
way, which was previously not possible. Gouveia (2018) also says that adding value to users
is the focus of digital marketing, and that posts must concentrate on this, so that the interaction
