Is there something different?? What are the differences between optimizing a site made it css or html and the one in Joomla??
I think Joomla is an award-winning content management system (CMS), which enables you to build Web sites and powerful online applications. Many aspects, including its ease-of-use and extensibility, have made Joomla the most popular Web site software available. Best of all, Joomla is an open source solution that is freely available to everyone. Am I right?
There are some nice tutorials HERE. You can go through them and get your site indexed in no time.. I used some of them... Its specially for Joomla sites only..
