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.
We highly recommend manually submitting your website pages to the major search engines such as Google and Bing. The search engines have implemented manual submission as a best practice to protect themselves from extreme levels of spam. The search engines however do not give any guarantee of ranking your page because you have manually submitted it. It is a tool that to let the search engines know that we have new information to share.
