The objective of the research was to identify statistically significant differences in selected engagement indicators on Facebook – likes and shares in relation to the different types of content that brands on this platform add to. The analysis was performed on a sample of three global companies from the top 25 most valuable brands in the world and their posts. Using quantitative statistical methods – MANOVA (Multivariate analysis of variance) and Gammes-Howell post hoc test, a total of 1,280 brand posts were analyzed in order to differentiate the liking and sharing of content types. Data collection was carried out in the first half of 2018. The findings pointed to two statistically significant differences that were also interpreted in the discussion of the research. The findings have shown that in case of liking, in two cases out of three, there is a statistically significant difference in terms of the type of content added, when photos came out as those with the greatest potential to get like from Facebook users and fans. At the same time, the same finding appeared in the case of sharing, which is an even stronger form of engagement. Likewise, photos were shown to be the most promising in terms of potential content sharing by Facebook users and fans. The study provided some clues as to where this research should go further and explore the relationship more deeply in view of the more extensive quantitative research, and also the potential qualitative approach. The future research directions include analyzing companies of different types and sizes and also taking into account the contribution from other social networks with the same or similar engagement indicators.

Although there were many consumer behavior studies, their focus was on traditional brands. Despite that, their conclusions and recommendations can serve as a model for private label research. This paper aims to find out the influence of packaging on consumer purchasing decisions in the yoghurt segment. Attention was drawn to Slovak consumers under the age of 25 years. To achieve the aim, survey, structured questionnaire (549 randomly chosen respondents) and blind test (20 respondents) methods were used. For a deeper analysis, four hypotheses were set out and tested using statistical methods of Pearsons’ Chi-Square Test, Friedman test, Mantel-Haenszel Chi-Square Test, Phi Coefficient, Cramer’s V Coefficient and correspondence analysis. The results proved that almost 58% of respondents bought private labels sporadically, over 20% of respondents bought them multiple times a week, and over 18% of respondents bought them once a week. In terms of perceived quality, it can be said that quality of private label products is perceived as good and adequate, they evoke impression of adequate quality at a reasonable price, the decisive factor for their purchase is a combination of reasonable price and quality, and the reasons not to buy are high price, low quality and lack of information about the producer. Regarding the impact of packaging on respondents’ purchasing decisions, it is found that less than 34% of respondents believe that packaging of private label products is unattractive, and up to 33% of respondents think that packaging does not affect them.
