Considering that individuals and organizations for different activities increasingly use social networks (SN), this paper seeks to describe the level of usefulness that business sciences university students find in them, and the impact thereof on their Academic Performance self-perception (APS). The results show that in both Mexico and Spain, the target audience considers that SN are useful for academic topics, this being more noticeable in the first country; Likewise, APS is better in Mexican students. On the other hand, using linear regressions as a statistical technique, in both nations was found that the more usefulness obtained from the SN, the higher students’ APS, which turned out more noticeable in the Spanish case. In today’s world, where thanks to information and communication technologies (ICTs), there are high possibilities for interconnection between people and organizations, these findings are of interest to universities, government bodies and companies because they all offer products and/or services to a public who needs to feel that the former know more and learn about them better, for which SN become a current and versatile tool for dissemination.
