Bread Crumbs, or BC, are navigational symbols represented by an arrow icon which enables both search engines and website visitors to understand the relationship and the hierarchical structure between related and nested web pages. Usually, the hierarchical navigation begins from the homepage, and continues onto the page on which the user is currently on (in other words, to the page level). The bread crumbs are consistent with the page’s URL hierarchy.
