Joomla! v 1.5 Search Engine Friendly URLs (SEF URLs) A. What are SEF URLs? SEF means “search engine friendly.” Websites are considered search engine friendly if the pages can easily be found by search engines. One part of this is nonparameterized URLs. In version 1.5, Joomla! offers three different options you can choose to build SEF URLs. Let's have a look at the normal Joomla! URLs: These URLs are very long and contain a lot of parameters. This makes it obvious the pages are constructed dynamically. Some believe Google and other search engines often ignore these URLs or don't place them at the top of the result list. Other than search engine impact, there are other advantages of SEF URLs: • The URLs contain keywords. • The URLs are much shorter. • The URLs are more “human friendly.” This is an advantage for search engines, because indexing your site is more accurate. Long URLs break in blogs and in emails where the shorter SEF URLs do not. Even for humans, SEF URLs are better because increased readability makes it easier to remember the address or to share a web page with friends. Combined, these benefits translate to more site visitors. B. Search Engine Friendly URL Configuration You have to do all important changes in the “Global Configuration” dialog.
