Duplicate pages with GET parameters

[Anttoniy97]

This is what search engines write in Joomla 3.9.28.

Some pages of the site contain the same content and differ only in the GET parameters in the URL, duplicating the content. Bypassing them, information about pages that are important to you can be transferred to the search base more slowly, which can affect the state of the site in search.

Why do you have to look for third-party extensions for the site to be indexed?
Maybe it's time for developers to fix such a bug !? Is there a patch for fixing duplicates?

Hi. This is not a bug, but the basic principle of operation of any CMS. Any CMS has duplicate pages. And in Joomla, this is not so bad compared to other CMS. To correct this at the development level, you just need to refuse to use CMS as such. And create a site on HTML.

Webmaster, with a sufficient skill level, can control it using htaccess and robots.txt. For those who do not have enough skills, all these extensions were created. Their principle of operation is exactly the same as working with the files specified above. Just all this is placed in the user-friendly interface.
