Abstract
The objective of this research is to understand the dissemination strategy employed by Spanish fact-checking agencies through their WhatsApp channels. Specifically, it analyses the theme and function of the publications, the type of misinformation verified, and the interaction and multimedia presence. Quantitative content analysis is used to analyse the 258 messages published by Newtral, Maldita, and EFE Verifica on their WhatsApp channels over two months. The results show some interesting findings. Firstly, it is noteworthy that Newtral and Maldita have a regular publication frequency, but not EFE Verifica. Secondly, the conflict between Israel and Palestine dominates a large portion of the verifications by Newtral and EFE Verifica. In contrast, Maldita focuses on informing about topics related to science and technology or politics. Thirdly, it is highlighted that only Maldita seeks to promote real interaction with users through reactions. These findings provide insights into the use of newly created WhatsApp channels by fact-checking agencies.
