Not what i hear of. Best way to promote your sites is to tag your site URL to your forum sig or make a blog about it and post your website URL there. Make sure the things you post in your website will attract the crowd. search engines only link your website to their engines if you have an important keyword in your website. Example: thinkpads... Then you will come to thinkpads.com website and .....bla...bla...bla... It takes lots of work to really attract severe crowd to your website.
Have good META tags.
Submit your site to search engines.
Put them in signatures.
Try to affiliate if possible.
Then go out and promote all over the internet such as chatrooms, blogs, etc..
