wernerandblank.com and cbravo.com are two strong general directories, with high traffic and pagerank, that will definitely improve the search engine ranking, link popularity and traffic of any website submitted to them. General directories are accepting almost every website, some of them are not accepting porn and illegal websites, but anything else will get in.

As a webmaster, use web directories to improve your search engine ranking and bring in more traffic by at least 2 ways: directly from the web directories and from search engines. Both ways are improved by web directories, that should be highly used by every webmaster, especially that most of them are free or extremely cheap.
