The Joomla CMS provides a neat little way to turn the standard ugly urls from their long, unfriendly format to a much more human readable 'Search Engine Friendly (SEF)" version.
Follow these two simple steps in order to make your Joomla system show friendly URLs!
to the much more readable and search engine friendly:
There are just two things you need to do to achieve this. In the Joomla administrator area, navigate to System > Global Configuration. On this screen the first tab is Site. On the right hand column, under the title SEO Settings set Search Engine Friendly URLs to Yes. A new field will appear 'Use URL Rewriting' which you can set to Yes also.
