What the visitors want.
...the most visited pages are not always those more frequently displayed?
Individual Web page popularity does not simply consist in how many times the page was displayed, but also in how many people visit the page and, especially, how frequently these people come back. Ascertaining the number of viewings per visitor and the number of visits per visitor in each page may show that people, based on certain information, like to come back. This fact should be taken into account when creating your navigation scheme.
