In the new era of technology, internet turns to be one of the main sources of information, since it is considered cheaper and easier to use. Hence in tourism, two main pull factors influencing potential tourist to visit a destination are recognized as nature and culture which a destination offers. The acceptance of culture as one of the important factors in tourists’ motivation, heritage sites become popular in many countries especially those which are nominated as world heritage sites. This paper is to analyze the condition of available online information about George Town world heritage spots (Penang, Malaysia). As far as heritage is one of the products of tourism and tourism, on the other hand, is a big help for sustainability of heritage sites, providing sufficient information about tourism heritage sites as a promotional key is very important. Top ten tourism websites were chosen and content analysis was performed to find the current situation of those websites. By recognizing heritage as tangible and intangible, the result shows that although the intangible heritages need more concern in sustainability matter, but the information about them are not as complete as the tangible ones. Lack of proper information was seen in most websites and the focus of information was more on tangible heritage and among intangible heritage, the main focus was on food. To support the result of analysis, in-dept interviews were conducted by couple of heritage offices in the city. The main reason behind the lack of sufficient information about intangible heritage seems to be the lack of complete list of them and moreover, promoting this division of heritage needs negotiation with the local residence involving in those activities. The paper suggests providing a complete list of George Town world heritage as far as some of them are disappearing lately, and keeping this valuable world heritage sustainable for next generation needs detailed study and completing the list as soon as possible. In this regard those intangible heritages which are in hazard of disappearing can be maintained by the effort of key holders of the field. Moreover, providing the mentioned list helps the information providers, especially related websites to focus equally on tangible and intangible George Town world heritage.
