What are Joomla SEF URLs?

How do I enable SEF URLs in Joomla?

Set Search Engine Friendly URLs to Yes in Global Configuration. To remove index.php , also enable Use URL Rewriting after configuring .htaccess , web.config , or nginx.

Why do I still see index.php in my URLs?

Use URL Rewriting is Off, or the server rewrite file is missing or ignored. SEF alone keeps index.php in the path.

Do I need .htaccess for SEF?

Not for SEF generation. Yes for Apache/LiteSpeed rewriting that removes index.php . Details: htaccess-joomla .

Should I add .html suffixes to Joomla URLs?

Usually no. Suffixes are optional cosmetics. Changing them later forces redirects across the site.

What are Unicode aliases?

When Yes, Joomla can keep native characters in new aliases instead of transliterating to ASCII. Choose based on audience and keyboard reality. It does not mass-convert existing aliases.

Will enabling SEF improve Google rankings by itself?

Not by itself. Clean URLs help usability and consistency. Rankings still need content, links, crawl health, and technical SEO.
