According to a statistics in 2013, 97% of Hong Kong people access the Internet with mobile devices, in which 84 percent will browse the web, and 74% of these visitors were converted into customers. These figures make businesses aware of the importance of web mobilization. Having said that, not many businesses has done it right. Recently, I found a Japanese-style furniture store through search engine, but the store’s website was built with Flash, none of its content could be seen during the web-browsing. A few days later, it was found that there is an App which supplemented the website, however, it must be downloaded and installed it from the Google Play/iTune by myself. The example tells that App Development may not be the best solution for Web mobilization. On the other hand, if some standard of a website can be done right, like the Responsive Design, the content quality and the Search Engine Optimization, can lead to more effective result, which of course, include the cost effectiveness.
