In today's dynamic environment, where factors are changing rapidly and competition in the market is increasingly important, quality and information is much wilder and more unpredictable. Moreover, today's environment is overwhelmed by information, and it is becoming increasingly difficult to reach those who can improve their performance. Competitive analysis of e-shops in the food industry was carried out. There are many food websites in the online world, but only a small percentage of them can succeed. The paper focuses on the topic of e-commerce with a focus on building a quality e-shop. This article also aims to link e-commerce to e- commerce quality. The main focus of the thesis is research, research of literary and scientific sources. Competitive analysis was carried out in the e-shop with groceries. This information will be further used in my doctoral thesis, which deals with building a quality e-shop in the food industry. Using the research results, it will be possible to make recommendations to other Internet businesses, but the specific methodological model of website tool implementation will be suitable for e-shops. In companies, the importance of e-commerce in web quality is underestimated. This can lead to a drop in sales or a loss of competitiveness.
