You can submit your site to Google by using the following link: http://google.com/addurl. Once submitted to Google, other search engines will index it too.

Each web application has specific search engine optimizations. For example Joomla has SEF (Search Engine Friendly) optimization. For more information on how to enable it you can check this URL:

If you are not using Joomla you should check the manual for your application for similar optimization.
