Once we have a site Joomla! pus pe un server online, putem in cateva minute sa il pregatim pentru a avea linkuri SEF , in acest fel facem primul pas in SEO . put a server online in minutes you can prepare it to have SEF links, thus making the first step in SEO.
At first glance, the links are like:
www.site.ro/index.php?option=com_content&view=article&id=19&Itemid=27
Which does not say very much or any new search engine (Google).
What to do:
1. Get in the administration
2. Above the menu Site -> Global Configuration
3. We have a tab on the right: SEO Settings and under it:
Search Engine Friendly URLs: No
Use Apache mod_rewrite: No

We (Yes) to both save the configuration.
NOTE:This information is contained in the configuration.php file which is in the root site. Din motive de SECURITATE , acest fisier este bine sa nu aiba drepturi de scriere (644) , asa ca dupa ce faci modificarea pentru SEO ai grija sa ii modifici drepturile. For security reasons this file you should not have write access (644), so after you change for SEO's sure to change the rights. Daca in momentul cand vrei sa salvezi o sa primesti un mesaj: If you want to save when you will receive a message:
An Error has occurred! Unable to open configuration.php file to write!
644 means that the file is from cPanel or FTP them change 666, 644 back and then make changes.
Now once I worked those 2 options, I saw the second tells us that only we can use mod_rewrite on Apache (the server that is where our new website). Se poate intampla ca unele servere sa nu suporte mod_rewrite, daca e asa sunam pe cei de la hosting si le spunem sa activeze acest modul. It can happen that some servers do not support mod_rewrite, if so I rang the people at hosting and tell them to work this way.
4. And last step is to change the file name to htaccess.txt. Htaccess file, htaccess.txt file is located in the root, if you lose it and Joomla!.
If you cache on site, when you refresh a page of links to SEF like:
www.site.ro/joomla-overview
is some difference from the previous one:
www.site.ro/index.php?option=com_content&view=article&id=19&Itemid=27
This is the easiest and quickest way to make SEF links from now remains to choose if you want to use anymore and another component, as sh404SEF, JoomSef or not.
