The error may occur because the Web site has been moved or deleted, or it may simply be on a server that is busy at the moment you try to access it. Click your browser's Refresh button. If you get the same error, click the browser's Back button and try the site later. If you continue to get the error, report it to us . Special robotic software programs periodically scan the directory for broken or outdated links.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.
