Why is a DMOZ listing so important?
The Open Directory Project (ODP) is known as DMOZ because of its original domain name, directory.mozilla.org and is a multilingual open content directory of web sites that is developed and maintained by a community of volunteer editors. Being listed in the directory is free. DMOZ uses a hierarchical system for organizing website listings. Listings are sorted into categories, which can then include sub-categories under them. Google uses DMOZ as a directory source so it is important to have your site listed in its index. Google’s own directory is actually the whole DMOZ directory. Robozilla which is DMOZ’s web crawler checks the status of all sites listed and periodically flags websites which appear to have moved or disappeared. This helps to reduce the link rot in its web directory. Now, it has been said that without a DMOZ listing you will not rank well in Google. This is not true, but it is one of the best authoritative links around.
