Major Web Directories
Web directories are designed for users seeking information on a wide topic or subject area: “India music industry,” “Education,” and “Government” Web directories present users with a menu of broad subjects. Users select the subject category that covers their particular area of interest, then select links to sub-menus closer to their topics until they find links to relevant resources.
Web directories can often point users to relevant information with just a few menu selections. Though there is no guarantee that every site linked to a Web directory will be accurate and relevant, the odds of finding irrelevant information in a Web directory are much lower than in the results of a Web search engine.
