A search results page includes multiple search lists generated by multiple clustering operations applied to an initial match set of documents selected based on a user query. A first result list is constructed by clustering a top-n set of documents by primary domain address and sorting based on extrinsic ranking factors such that the first list includes a ranked and ordered list of primary domain linked anchor text. A second result list is constructed by clustering the top-n set of documents based on a unified ranked occurrence of keywords within the top-n set of documents. The generated second list contains a plurality of cluster class references with each of the cluster class reference including a ranked ordered sub-list of the keywords occurring within the top-n set of documents and respectively associated with the cluster class reference, each of the keywords of the ranked ordered sub-lists including linking references to a corresponding one of the top-n set of documents. A third result list is constructed by clustering the top-n set of documents based on a ranked frequency of occurrence of internally linked anchor texts. The generated third result list includes the top-n set of the internally linked anchor texts and respective ranked and ordered sub-lists of linking references to primary domain Web-pages containing the corresponding one of the internally linked anchor texts.
