I already know that i should submit my website to search engines and to web directories, any other suggestions?

There are many ways that would help you increase your google page ranking and increase traffic to your website:

1st try to get more back links to your website and the easiest way to do that is by submitting your website to free web directories such as:

http://www.lii.org

http://www.dmoz.org

http://www.surformation.com

2nd Try promoting your website on social networking websites such as twitter

3rd and most importantly, provide quality content, this is an indirect way to get back links by genuinely driving people to link to your website,
