You now need to select the two most important keywords for your site based on their popularity. If you don't yet know the keywords which are applicable for your site, have a look at my article on Choosing the Correct Keywords for Your Site.
In this article, I have mentioned that while selecting the keywords for your site, you should look at both the popularity of the keywords as well as their competitiveness. However, for the purpose of this article, don't worry about the competitiveness - select keywords only on the basis of popularity.


Broadly, here are the rules that you should remember when forming the description:
i) Make sure that the description can tell a visitor what your site is all about.
Things like "Have a look at our site" or "Welcome to my site" does not tell a visitor what your site does.
ii) Avoid hype of any sort.
Avoid using ALL CAPS or exclamation marks. Phrases like "The best web site dealing with widgets!!" or "Offers the BEST QUALITY, CHEAPEST WIDGETS you can find anywhere" are inappropriate.
iii) Don't capitalize every word in your description
capitalize only the first word. Of course, if some of the words in the description are proper nouns, then you should capitalize them.
iv) Write the description in the third person.
Don't say "We offer financial planning and credit counselling services", say "Offers financial planning and credit counselling services.".
v) Don't make your description too long
limit yourself to 15 words at the most. If you are lucky, you may be able to get accepted with a description longer than 15 words. However, the longer the description, the higher the probability that the editor will want to edit it.
vi) Check your description for typos and grammatical mistakes.
vii) End your description with a period. If the editor has to add the period to the end of your description, she may also end up editing the description, which is not what you want. Your aim is to have the editor accept the exact description that you had written in order to ensure that your keywords are not removed from the description.
Now, we come to how you can select the right category for your site. Go to the Open Directory, and search for the two keywords you have established. Does a particular category come up at the top for both the keywords? If so, go to that category, and see whether the sites present in the category are similar to yours. Also see whether that category has a Description and/or a FAQ. Read them and find out whether that category is applicable for your site. If so, this is the category you should submit your site to.
If different categories come up at the top for the two keywords, go through all the categories and find out which is the most appropriate category among the different categories.
For some keywords, you will find that the Open Directory does not display any categories. In this case, find out which category most of the top sites belong to and submit your site to that category, assuming it is applicable for your site.
Once you have selected the right category, click on the "suggest URL" link at the top. Type in the address of your site in the first text box, the official name of your site in the next text box, the description that you have earlier developed in the third text box and your email address in the fourth text box. Although the Open Directory says that including the email address is optional, I would recommend that you include it - if, for some reason, your site is not accepted, the Open Directory editor may want to tell you why your site has not been accepted.
What To Do if Your Site is Not Accepted
After submitting your site, go to the category where you have submitted your site every day and see when your site gets listed. If you find that your site is not in that category, it may so happen that you have been placed in a different category. Type in your domain name in Open Directory's search box and see whether your site comes up in the results. I have seen some sites getting accepted within 1 day and some sites in about 2-3 weeks.
