Breadcrumb navigation (Breadcrumb trail)
A type of secondary navigation that helps the user figure out their location on your website. Links appear horizontally providing a link to each previous page on the website.
It is beneficial for both user experience and crawling, as it provides an improved internal link structure for large sites.
They can also be displayed in the SERPs instead of the usual site URL. This creates links that are readable and user-friendly. You can set this up with the Yoast plugin if you are using a WordPress website
