Directories are one of the easiest way to get links for your website to increase it’s strength and ranking in the search engines. Their advantage is that they’re very cheap or even free and you get quite related links, by putting it in the right category, with a description and on the same page with other websites with description related to yours.

But you should choose wisely, when trying to submit in directories, because not all are good, especially when you pay for the submission. Two good directories are the Dirmoz web directory and Deluxe web directory, both paid directories that offer quality links for a low price.

Also, if you are a directory owner you may want to submit it into the directory of directories.
