4SEO is a modern integrated solution for Joomla search engine optimization. It constantly analyzes your site for changes, identifies important pages, adds meta and structured data, optimizes for publication on social networks and creates a site map. 4SEO also provides you with tools for everyday SEO work: a list of broken links, customizable error pages, redirects, content replacement, robots.txt

Info:

Works like Google or Bing
Like a search engine, 4SEO scans your site in the background to understand it and gather information about each page.

It automatically detects multiple URLs for the same content, adds rel = canonical links and makes sure that duplicates are not indicated in the site map. And detects duplicate page title or description and many other important SEO information.

Measuring Real Core Web Vitals
Core Web Vitals are new speed factors that Google uses when ranking pages. They are difficult to measure because Google uses real visitors to collect them.

4SEO provides you with real and accurate Core Web Vitals values measured based on your real visitor experience. These are the same values that Google uses, unlike all online speed testers. And 4SEO can show you exactly which pages failed the speed check earlier than Google.

Fast and easy on your server
4SEO is integrated: data is collected only once, in the background. When your page is displayed to visitors, a minimum of work is required for maximum speed. With separate extensions, the same work must be done multiple times, which leads to a decrease in performance.

4SEO replaces metadata extension, sitemap extension, structured data extension, social media sharing extension, redirection extension, content substitute extension (and more) with just one quick extension.

Metadata in the admin panel ...
Manage and create the page title and meta description in one place.

4SEO demonstrates an accurate, live simulation of Google search results for both mobile and desktop computers. Adding robot tags happens in one click.

... or on the frontend
Grant access to the interface only to authors or SEO specialists, and they will be able to visually customize metadata and share images. They can perform Facebook and Twitter verification with one click.

Structured Data Generation (Rich Snippets)
Maybe the most important SEO action you can take on your website in 2021?

4SEO automatically generates structured data for your content. Search engines will understand your content better. Extended snippets will bring more traffic.

Create simple rules for structured data types supported by Google. Rules are applied from one page to many URLs, components, or categories. Built-in rules allow you to get started without configuration.

Social Media Sharing Tags
Sharing content on social networks only works when certain metadata is enabled: OpenGraph and TwitterCards. 4SEO generates them automatically.

But what is really important is the inclusion of the correct image. Publishing without an image costs nothing, so 4SEO detects images in your content and selects the best image. You can change this choice either in the admin panel or directly in the user interface.

Generating an XML sitemap
A sitemap in XML format is important for SEO only if it does NOT contain all the pages of your site.

4SEO automatically creates, updates and sends to Google and Bing a site map optimized for SEO: canonical URLs are included, duplicates or archived content are excluded. The robots meta tag and file are respected robots.txt .

4SEO also automatically removes content older than the number of days you specified for the desired categories from your sitemap.

A plugin is not required, all the creation of a site map is based on a constant full analysis of the site. Special support for Hikashop, J2Store, Virtuemart, IgniteGallery or Phoca Gallery optimizes even more site map URLs or image selection.

Error Detection
When reading the content of your site, 4SEO detects broken links and tells you which pages they appear on so that you can fix them quickly.

But it also records PHP errors so that you are aware of possible errors that maybe only your visitors have seen so far. With an accurate description of the error, file name and line number, developers can quickly fix the situation.
