Breadcrumbs actually means breadcrumbs. So breadcrumb navigation. Because breadcrumbs are navigation elements that are often integrated in the upper part of the website. These breadcrumbs make it relatively easy to navigate within the website structure.
An example could look like this:
Home > Offer > Web design with WordPress
Incidentally, the term breadcrumb comes from the fairy tale “Hansel and Gretel”, who used crumbs to mark their way back home. Breadcrumbs make it very easy to find your way back to the relevant pages and avoid getting lost in the website forest.
