What Is Dmoz ? Dmoz (Directory Modzila) also known as ODP (Open Directory Project) is a directory, which like everything is edited directory, only this is the most important and extensive that there is on the Internet, maintained and updated by volunteer editors.

If want to include your site in this directory you enter: "suggest URL" and revise their policies first shipment of sites, this is very important because of not understanding that it is run the risk that your site is rejected. It is also important to look great in the direction you give your site, you must include it in the category and sub categories is necessary for accurate and that you take your time and think about very well because they let you clarified that are highly selective and do not accept all sites. Note that it is very important that you choose the category that best fits the theme of your website, once completed the registration process you must wait for an editor review your site and this step takes quite a while, so that arm patience is not an easy process but the wait is really worth. It is desirable that after your site is not accepted try again in another category because if a publisher is detected, you will almost certainly reject. One thing to consider is that there are categories PageRank of 8 so that a link in Dmoz is certainly advantageous. But as I said the wait is long and can take up to six months. All sites in Spanish are included in a category under "Spanish World" Well, to begin now the process of signing up in Dmoz, knowing that it is a long process but it really will be very beneficial to your website.
