Should I use breadcrumbs on my website?
Breadcrumbs are an important part of almost every good website. These little navigational aids don't just tell people where they are on your site, but they also help Google work out how your site is structured. That's why it makes a lot of sense to add these helpful little pointers.
Why is it called bread crumbs?
A “breadcrumb” (or “breadcrumb trail”) is a type of secondary navigation scheme that reveals the user's location in a website or Web application. The term comes from the Hansel and Gretel fairy tale in which the two title children drop breadcrumbs to form a trail back to their home.
