Joomla SEF URLs

6. Now Enable Search Engine Friendly URLs & Add suffix to URLs which will look as follows:

Why we enable SEF & Add suffix URLs means it change the URL from "http://www.questionkit.com/index.php?option=com_content&view=article&id=9" to "http://www.questionkit.com/index.php/blog/4-blog/9-joomla-css-got-corrupted-when-i-enable-sef.html"

Add suffix to URLs is used to add .html at the end of each URL. So If search engine like google, yahoo, etc will consider the page as a static one.

Search Engine Friendly is used to change URLs from id values to alias values. You can find the alias value below each title of the article in Joomla Admin Article Manager. Alias value will be generated only on saving the article. You can also enter your own Alias value.
