Help build the largest human-edited directory on the web. Soumettre un site - Open Directory Project - Devenir Editeur

Web directories list the websites by theme. The links in a web directory are collected, edited and organized by humans. Yahoo and Dmoz ODP(Open Directory Project) are considered as the best human-edited web directories on the Internet and they are one of the most trusted and relied traffic sources. Since these directories get thousands of submissions every day, it is sometimes difficult to get listed in them and your URL may take a long time to be reviewed and listed. Generally good directory listings give a surprise boost to your link popularity.
