Here is a short  list of some directories I have found recently that have offered speedy service and high quality links. Submitting your website to directories is a proven method for increasing your site’s pagerank, traffic, and visibility in search engines (including google).
Something that I value when selecting a web directory is a short URL. Here are a few directories I have found with short URLs:
http://lupp.info - A 4 letter URL directory with low price links
Here is a small directory network I found containing three different 4 letter URLÂ directories. All of them appear to be powered by the latest version of phpLD and are reasonably priced:
http://cymq.com
http://dvxk.com
http://dzux.com
Always do some research before submitting your site to a directory. Check that the site is high quality and is ranked in google. Also examine the quality of the links in the directory to make sure you aren’t paying to be listed in a directory full of poor quality sites.
