Submit to Open Directory Project - ODP

The Open Directory Project is the largest, most comprehensive human-edited directory of the Web. It is constructed and maintained by a vast, global community of volunteer editors.

According to ODP website:
The WWW continues to grow at an enormous rate. Automated search engines are increasingly unable to turn up useful results to search queries. The small paid editorial staffs at commercial directory sites can't keep up with submissions, and the quality and comprehensiveness of their directories has suffered.

The Open Directory provides the means for the Internet to organize itself. As the Internet grows, so do the number of netizens who can each organize a small portion of the web and present it back to the rest of the population, culling out the bad and useless and keeping only the best content.

The Open Directory was founded in the spirit of the Open Source movement, and is the only major directory that is 100% free. There is not, nor will there ever be, a cost to submit a site to the directory. The Open Directory data is made available for free to anyone who agrees to comply with their free use license.

The Google Directory and over 300 others use information from ODP to provide directory and search services. It may take months for some to update their listings. So be patient. Google will treat you favorably once you get admitted to ODP and may boost ranking of your website.

ODP is a volunteer-edited directory.
Read Submission Guidelines and Editor Guidelines.

One thing about ODP is that they face shortage of editors for their unpaid job. In the worst case scenario, it might take months, sometimes years your website will be reviewed.

When you are ready, start submitting the root address of your website, i.e., your "Home" address. Submitting once is enough. Repeating will not help. Read the above two guidelines. They are mostly self-explanatory.

What If Rejected
Unfortunately ODP does not inform you if your website is rejected. There is simply no way to know unless you can get an editor to check it. Read again the Editor Guidelines and see if you can apply to become an editor and try to see why your website was rejected.

An article from ODP Newsletter is a good read about deep linking.
