One of the challenges that consumers faced with Mobile Internet is that they are only equipped with a small screen for browsing WAP contents. This makes navigating to WAP sites of interest on WAP portals which is usually organized in a multi-level tree hierarchy structure a hassle. This paper proposes methods for making WAP portals adaptive. Such portals reduce time spend by consumers in navigation henceforth more time for content browsing. The proposed methods implicitly track consumers' navigation activities among WAP sites and use these input to form the basis of consumers' preferences for adaptation. These methods are:

• Adaptive Link Sorting

• Adaptive Recommendation

• Navigation Shortcuts The methods had also taken into account possible drift of consumers' interest over time. Weighted computation is used to achieve adaptation that will be of relevance to consumers at any point of time. Preliminary experiments with mobile users have yield promising results
