You can submit to few free Directories online. It is not worth it to pay to submit your website to directories. There are some good quality directories out there like Yahoo or (if you can stand to wait years if you are unlucky) and DMOZ. A link in ONE OR TWO of these directories will probably get your site into search engines. Unfortunately, there is a LOT of low quality links you will probably stumble upon first, and these kind of links can quickly turn toxic.
