Search engine friendly (SEF) Search-engine friendly URLs. Refers to URLs that are descriptive in a way that search engines can understand. Normal Joomla! URLs look something like this: http://www.yoursite.org/index.php?option=com_content&view=section&id=3&Itemid=41 You can optionally have URLs display to look like static HTML pages like this: http://www.yoursite.org/faq.html Joomla! 1.5 has built-in optionos for SEF URLs. These are enabled by changing the ""SEO Settings"" in the Site tab in the Global Configuration screen in the Joomla! back-end. There are also third-party extensions that create SEF URLs for Joomla!.

Alternative Menu item Alternative Menu Items are used and work the same way as standard menu items. Since they are already based on customised layouts, template overrides do not apply to alternative menu items.
