The same process for Yahoo is about the same here for submitting your site . You must find your category and then click ADD URL at the top of that category's page. AOL still has a robotic search engine by default as well, but all new submissions must go through DMOZ.org. If you have already submitted your site to DMOZ, then you do not need to submit your site here . Looksmart is a human directory.
Submission is free for non-profit organizations.
It usually takes about 4 weeks to get listed here. But it all depends on when you submit. If not, you may have to wait a while. But this is how most robotic search engines work. Also, it is best to re-submit your site at least every 6 months.
