Bread crumbs – SEO WIKI
Breadcrumbs are an element of navigation on an Internet resource.
In other words, this is a navigation chain – that is, the path from the main page of the site to the one on which the visitor is currently located. And the unusual term “bread crumbs” was borrowed from a famous fairy tale, whose heroes, in order to find their way home from the forest, sprinkled bread crumbs on their way.
Breadcrumbs are used on those Internet resources that have a complex structure of sections (or headings). Thanks to the navigation chain, the user can easily and quickly figure out which sections of the site he visited.
