A web directory or link directory is a directory on the World Wide Web. It specializes in linking to other web sites
and categorizing those links. A web directory is not a search engine and does
not display lists of web pages based on keywords; instead, it
lists web sites by category and subcategory. Most web directory entries are also
not found by web crawlers but by humans. The categorization is usually based on
the whole web site rather than one page or a set of keywords, and sites are
often limited to inclusion in only a few categories. Web directories often allow
site owners to directly submit their site for inclusion, and have editors review
submissions for fitness. RSS directories are similar to web
directories, but contain collections of RSS feeds, instead of links to
web sites.
