Free Content Websites (FCWs) are a significant element of the Web, and realizing their use is essential. This study analyzes FCWs worldwide by studying how they correlate with different network sizes, cloud service providers, and countries, depending on the type of content they offer. Additionally, we compare these findings with those of premium content websites (PCWs). Our analysis concluded that FCWs correlate mainly with networks of medium size, which are associated with a higher concentration of malicious websites. Moreover, we found a strong correlation between PCWs, cloud, and country hosting patterns. At the same time, some correlations were also observed concerning FCWs but with distinct patterns contrasting each other for both types. Our investigation contributes to comprehending the FCW ecosystem through correlation analysis, and the indicative results point toward controlling the potential risks caused by these sites through adequate segregation and filtering due to their concentration.

翻译：免费内容网站（FCWs）是网络的重要组成部分，认识其用途至关重要。本研究通过分析全球FCWs，考察了它们与不同网络规模、云服务提供商及国家之间，根据其所提供内容类型而产生的关联性。此外，我们将这些发现与付费内容网站（PCWs）的结果进行了对比。我们的分析得出结论：FCWs主要与中型网络相关联，而这类网络往往与更高比例的恶意网站集中相关。同时，我们发现PCWs与云服务和国别托管模式之间存在强相关性。此外，在FCWs上也观察到一些相关模式，但两种类型网站呈现出相互对比的独特特征。本研究通过相关性分析，为理解FCW生态系统作出了贡献，其指示性结果表明，鉴于这些网站的集中性，应通过适当的分隔与过滤来管控其潜在风险。
