Google breadcrumbs
 

For sites that Google has deemed to have decent authority, they will auto create breadcrumbs which is a marked advantage against your competitors

Google has endorsed use of breadcrumbs in several of their videos. They are a helpful device for website with complex structure or hierarchy such as eCommerce sites. They not only aid user navigation but also help search engines get a clearer picture about your site's structure. For example if you're using faceted navigation you could end up on a product page that has a long URL and ambiguous placement in the site's hierarchy.
