That used to be the case... but modern search engine algorithms take into account dynamic pages and it no longer effects SEO to use a single page with url parameters to swap content.
However it is still considered best practice to use friendly URLs for the variety of other benefits. This is commonly done with a mod rewrite in the .htaccess file, so you could use a url like: index.php/contact if your server was configured for it.
This extension would work with friendly urls even though it doesn't include functionality explicitly to create them.
Did this help? Tips are appreciated...
