A breadcrumb is a secondary navigation within a website that shows the user where they are in the page hierarchy. Breadcrumbs are usually displayed as a horizontal list of links that map the path from the home page to the current page. Each link represents a level in the hierarchy and is often separated by symbols such as ">" or "/".

Breadcrumbs offer users an easy way to return to the previous page or a higher level of the hierarchy and help to improve the user-friendliness and orientation on a website.
