Background. Some mobile devices can access the Internet, but screen display size is a major restriction, due to size limitations. Different solutions have been developed to overcome this problem. The first uses a transcoding server which accesses the original site and converts standard HTML (Hypertext Mark-up Language) pages to WAP (Wireless Application Protocol) pages. The second approach uses a specific browser that runs on the mobile platform and displays the site in a vertical format. The most popular approach is the transcoding server, for specific usability issues. Aim. A study was done to determine whether or not relevant information is lost during the content filtering and extraction phase. Method. The study was done using a qualitative approach. Results. The study shows that the more complex a webpage is, the more difficult it becomes for the algorithm to extract relevant information. This is especially true when accessing e-commerce sites, which traditionally contain complex structures. Conclusions. For designers to support both the traditional PC platform and mobile devices, a guideline would be to keep a webpage as simple as possible. It was shown during the study that text based sites are easily converted.
