Breadcrumb and structured data

Hello,
I can read on your site: “TSF v5.0 added breadcrumbs to every post, page, term, and archive. These are outputted for search engines via structured data, but you can also output them directly on your site via a shortcode.”

> Does this mean that output them on the site adds nothing in terms of SEO? If you do it, it’s only for the users?

Tks a lot
