Joomla SEO Extensions & Plugins
A limited selection of approved SEO and performance-related Joomla extensions.
4SEO by Weeblr
This is my favorite SEO extension. It allows me to manage SEO metadata from the frontend very easily. Also for sites that I build using Yootheme Pro, it makes access to the metadata section very easy.
In the backend, many advanced options are available, but a lot is done automatically, like providing correct canonical URLs, and generating Open Graph data. It constantly analyzes your site to detect changes, identifies important pages, adds meta and structured data, optimizes for social sharing, and builds your sitemap.
4SEO also provides you with tools for everyday SEO work: a list of broken links, custom error pages, redirections, canonical tags, content replacement, robots.txt, and more.
Finally, it connects to Google Search Console to inform you about keywords you should use and pages you should link to.
This extension is specially made to assist you in the SEO process of your website's content. The key feature is that it gives you hints on how to optimize your articles for a given focus-keyword. It is well suited for both beginners and site administrators that need to allow end-users access to metadata.
This extension is from the same developers as the famous PWT ACL extension, and they also have a lovely sitemap extension.
RSSEO! is a very impressive SEO extension that I can highly recommend, built by RSJoomla! It is relatively easy to use, but also contains power-tools for advanced users. And contrary to some of the SEF extensions, the risk of messing up your site is low. This extension is a paid extension, you need a subscription (starting from €29), but it's worth the money.
OSMeta is meant to be used as a central dashboard for managing your Joomla articles metadata. There are more extensions that provide this functionality, but some of those are quite extensive with a lot of additional features and complexity. If you just need a central overview, OSMeta is a really nice extension. Also, it does not add a separate layer of administration, like others sometime do. It does not matter if you create your metadata within the Joomla article, or from the central dashboard, it is the same (core) field you are editing. This means you could have the central dashboard for the main administrator, while less powerfull users can simply create an article with corresponding metadata.
This is the sitemap extensions for pro's. For beginners it may be a bit too complex, but advanced users will be able to tune their sitemaps just as they want, with also a lot of SEO features on board.
