With the goal of all businesses, including those in the dairy industry, to climb their website rank in the world web, it is particularly important to implement well-planned promotions and actions in the appropriate communication channels. These channels are now being used as business tools, and therefore, planning, monitoring, and constant updating of the corresponding strategy. This paper examines the effect of big data, collected from the websites of 5 well-known dairy firms, based on their financial and ESG results, by performing statistical analysis (correlation) and Fuzzy Cognitive Mapping (FCM) scenarios, on the global ranking of these dairy businesses. Throughout this study, it is discerned that a significant number of dairy firms' website data, such as social traffic, unique visitors, backlinks, referring domains, referral traffic, paid traffic, direct traffic, search traffic, organic keywords, organic traffic, mobile traffic, and desktop traffic, should be utilized by their marketers and receive further improvement, through investment, due to their ability to enhance the ranking of dairy firms' website in search engine results.
