Las técnicas SEO son conocidas en el ámbito académico, pero su evolución en los medios en línea para elaborar noticias sigue en crecimiento, especialmente en su relación con la IA y el monitoreo de noticias. Este trabajo presenta los resultados de una revisión sistemática del framework PRISMA-SCR, con el objetivo de identificar la evolución del SEO en el periodismo en los últimos cinco años, los desafíos éticos y de calidad de información asociados a la optimización para buscadores, y la interacción entre SEO, IA y monitoreo de noticias. Los resultados muestran preocupación por cómo la búsqueda de visibilidad web puede superponerse a los principios éticos del periodismo, reducir la diversidad de contenido y propagar la desinformación, creando "burbujas de filtros", revelando así un vacío en este ámbito. Dada la escasez de investigaciones profundas, este estudio destaca la relevancia de debatir la estrecha interrelación entre SEO, IA y monitoreo de noticias.

This article analyses the political communication on Twitter of the Government of Spain at the height of the Covid-19 pandemic. The #estevirusloparamosunidos campaign on Twitter is monitored during the dates with the worst results in terms of fatalities (March 31th- April, 4th, 2020). The sample included in total 398 523 tweets in four data sets. Through the Social Network Analysis, the main actors and the main interactions between users are identified. The research shows a high coincidence between the typology of the Press Conference Spokespersons and the main actors on the analyzed hashtag, prioritizing the Spanish Administration and the Armed Forces. There was also a high relationship of the main opinion leaders with their “natural spectrum”. We conclude that in this hashtag there was a “war-like” atmosphere. Via the computer-based text analysis we identify that the word ‘government’ was mentioned more than medical words and that there are present some military-like terms.

The purpose of this paper is to present a methodology of analysis of TV series, taking into account the use of reality and fiction in the narrative construction of these series, as well as the use of verosimilitude in „real-world‟ series. With the methodology chosen, the purpose is to distinguish between the usage of reality and fiction, on one hand, and the usage of thematic recurrence, myth and metaTV references, on the other. The methodology consists of the edition of televisual text. For, inasmuch as we consider that drama series are a text, they can be edited. The empirical analysis deals with three US TV series: Lost, ABC: 2004-, CSI: Crime Scene Investigation, CBS: 2000- and The West Wing, NBC: 1999-2006. They all belong to the drama‟s era, but each of them represents a specific subgenre: adventures and science-fiction, crime and forensic, and workplace and politics.
