If I have a website that uses Linux servers and has a URL structure like the following...

http://www.nameofsite.com/index.php?...-your-business

...what steps do I need to take so that sitewide I can make the URL structure be more SEO friendly like this...

http://www.nameofsite.com/start-your-business

I realize it's probably something to do with the .htaccess file but what exactly? And will I need to create a new page for each URL?
