SEF Extended extends the functionality of Joomla's standard System - SEF plugin without replacing it. The standard plugin must remain enabled.
The plugin adds advanced tools for Canonical URL generation, URL normalization and management of selected settings of Joomla's standard SEF plugin.
Canonical
SEF Extended generates and adjusts Canonical URLs using the Joomla router. It takes menu structure, current route parameters, and component settings into account.
adds a Canonical URL when one is missing;
replaces technical or duplicate Canonical URLs;
can preserve Canonical URLs generated by other extensions;
removes GET parameters from Canonical URLs;
provides separate handling for tracking, pagination, and search parameters;
supports a configurable list of additional GET parameters to exclude;
supports exclusions for selected components and page types;
supports pages without a menu item and technical /component/ URLs;
when a matching menu item exists for a technical URL, the Canonical URL is generated using the menu item's SEF route.
For excluded components and page types, SEF Extended does not generate its own Canonical URL and does not remove a meaningful Canonical URL created by a specialized extension. Only a technical self-canonical matching the current URL is removed.
Redirects
The plugin performs 301 URL normalization. Domain redirects are based on the Site Domain value configured in Joomla's standard System - SEF plugin.
Redirects can be enabled independently for:
protocol mismatch;
www or non-www mismatch;
domain mismatch;
the presence of the .html suffix when Joomla suffixes are disabled;
duplicate slashes in the URL.
When multiple URL corrections are required at the same time, SEF Extended combines them into a single final 301 redirect, avoiding unnecessary redirect chains.
If domain redirects are enabled while the Site Domain setting is empty, the plugin displays a warning in the configuration.
System - SEF
A dedicated tab provides access to selected settings of Joomla's standard System - SEF plugin. These settings are not duplicated in SEF Extended: the plugin reads and saves the corresponding parameters directly in the standard SEF plugin.
This makes it possible to manage related SEF settings from one interface while preserving Joomla's standard architecture.
SEF Extended is designed for websites that require more precise control over Canonical URLs and URL normalization without replacing Joomla's standard router or System - SEF plugin.
Removed custom 404 page handling and its settings.

What I love about working with the guys at Joomla Center, besides their excellent knowledge of their craft, is their patience and politeness. No irritation at stupid questions, no arrogance, no eye-rolling, no heavy sighs. On the contrary, they explain things very politely and clearly, give recommendations, do things quickly and competently, and if something goes wrong, they'll fix it just as quickly. Five stars on all counts! As they say now, I'm hooked!
I want to express my sincere gratitude to the Joomla Center team for their professional assistance! After my site was hacked, their specialists quickly identified and eliminated all the consequences of the attack, patched vulnerabilities, updated the software, and restored the site to its original state. I was especially pleased that the work was not only done efficiently but also with detailed explanations of all the steps taken.
You guys are the best. You're always there to help and solve any problem. Today, a cybersecurity information site was down. Anton solved the problem in a couple of hours. Great job. I highly recommend you!!!
