Viral marketing is a communication strategy in which people quickly transmit a message to others, with the goal of making that message grow rapidly through dissemination. It\'s similar to the old-fashioned word-of-mouth marketing, but virtual and fast. One of the objectives is to achieve virality of the message, ideally transmitted through videos, comments, podcasts, etc. To measure the success of these types of campaigns, it\'s necessary to apply a set of techniques through internet channels, supported by social media. The purpose is to increase sales of a particular brand\'s products and services, as well as optimize its online presence. It\'s important to understand that viral marketing is not an end in itself, but rather part of a strategy whose purpose is to create a snowball effect among people who will share the message with their friends. This type of advertising content is always welcome among people, as it\'s something that truly appeals to the audience. Furthermore, it\'s not intrusive.
