Dmoz (the Open directory PROJECT/ODP) is a collection of manually edited directories that provide results or data for search engines. Most of these manual editors are volunteers, so it is not an easy thing to add DMOZ to the site, and some sites even need more than a year to be included ....
But do not be discouraged, because by DMOZ included with Google has the same important significance, many webmasters believe that the DMOZ included even than the annual cost of $300 paid to collect Yahoo is important.
DMOZ is now used by most major search engines. This fact proves that DMOZ is the most important submitting object and why thousands of websites have spent months asking DMOZ editors to add their own sites to the directory. The ultimate benefit of being eligible for DMOZ is that you can get a good ranking on other search engines, which is more beneficial than the Dmoz site alone (http://www.Dmoz.org).
Google's top three locations are more likely to be reserved for sites that join DMOZ at the same time;
AllTheWeb Join DMOZ's homepage/website to improve rankings;
AOL Search is a hierarchical directory organized by topic. All AOL user-submitted web site content is maintained by Open Directory Project (Open Directory projects), DMOZ;
HotBot and its parent company Lycos also use DMOZ data;
AltaVista also uses DMOZ to support its site search;
Inktomi use DMOZ to purify their list of results, or to search for quality control;
Netscape, etc...
These are the famous search engines on the Internet, and there are hundreds of smaller search engines and directory indexes that use DMOZ data at the same time.
Now you can see the quality of the results DMOZ has provided to the web community and the value behind these results.
As long as your site is dmoz into the index directory, it will also be displayed in other search engines. Google's catalog search results are directly using DMOZ. Using the DMOZ database of search engines and other directory indexes also have their own tuning algorithm, but the public opinion that included in the DMOZ site rankings in these search engines will be improved, this phenomenon is particularly inclined to focus on link popularity of search engines, such as Google.
Adding DMOZ also leads to hundreds of links to your site, which come from other directories or search engines. Because the search engine and catalog recognize the value of your site, so the site in the search engine rankings will improve. Why wouldn't it be like that? If 200 people told you to buy a gift at a store, you would seriously consider that store, right?
how to get the best results outside of DMOZ
Many webmasters simply submit the site's homepage to DMOZ, which is wrong. DMOZ no spider program can follow the homepage link to search, so, only the site's homepage was added to the directory database, and other pages are not included.
