Special robotic software programs periodically scan the directory for broken or outdated links. Editors then check the error reports to redirect the directory to moved pages when possible.
Human editors place Web sites into categories and subcategories.
Within each category, Web sites are listed in order of relevance. Relevance is based on AltaVista algorithms that take into account such things as the frequency of words on the page and how close the words are to the top of the page, proximity of words, popularity of the site, text in HTML meta tags, and many other factors. Even more important than size, however, is quality. Generally a Web site is listed only once. When an editor submits a site, special software checks to see if the site is already listed.
