What does it mean to de-index pages with arguments?

What is a page with arguments?

Pages with arguments are pages whose URL contains parameters.

For example:
- The search page, whose URL contains the search term.

- Category pages, especially from page 2 onwards, which contain pagination.
- Category pages with search filters.

Here is an example of a page whose URL contains parameters:

In this example, "controller" and "arg" are the arguments of this URL.

What happens when I choose to de-index these pages?

When you choose to de-index pages with arguments.

All pages whose URLs contain parameters will be set to "noIndex".

They will therefore no longer be taken into account by Google and other search engines.
