The aim of this chapter is to evaluate the website of Turkish companies in service industry which are listed in İstanbul Stock Exchange. Within this framework, two different dimensions are identified by considering technology acceptance model. On the other side, six different criteria are also defined based on SERVQUAL method. Fuzzy DEMATEL method is used to weight dimensions and criteria. Moreover, fuzzy VIKOR and fuzzy TOPSIS approaches are considered to rank the service companies according to the website overall performance. The findings show that being user friendly is the most significant criterion with respect to the website effectiveness. Another important result is that banks are on the first rank for this aspect whereas telecommunication companies have the lowest performance. Therefore, it is recommended that telecommunication companies should firstly focus on improving the factors that make the use of website very easily for the investors. This situation attracts the attention of these investors and it has a positive influence on the financial performance of these companies.
