Submit to Directories to Promote your Site

Submitting to directories can be a great way to get one way links. Many are still free. Some of the more popular ones are

Yahoo Directory
DMOZ
BOTW 
And new directories are created every week. Often new directories have a high acceptance rate. Some good places to find new directories as they are launched are:

Vilesilencer Announcement List
phpLD Advertising and Exchanges Forum

Directory Critic New Directories Section

If you have a new site, and want to get some links to boost your rankings or even just to get the search engines spidering you, this can be a great tactic to get things going. Good luck.
