SEO Tab:

Search Engine Friendly URL's:  This feature changes the way site links are presented and optimises them so that Search Engines can access more of your site.

This option is ONLY available to sites hosted on Apache servers.

Select Yes to enable Joomla! to output friendly URL's rather than normal, database generated URL's. If this feature is used then the htaccess.txt file must be renamed to .htaccess. This file is located by default in the root (or top) directory of your Joomla! installation. Select No to disable this feature.

Dynamic Page Titles:  Choose Yes to set the page descriptions that appear at the title bar of a viewers browser, to be the same as the page title they are viewing, rather than just the Site Name as entered in the Site Tab above. Again this helps Search Engines.
