Breadcrumbs is a secondary navigation element that shows a user's current location and a hierarchy among levels. It allows the user to move up to higher levels in the hierarchy or to a previous step.
On websites that have a lot of different pages, breadcrumb navigation can greatly enhance how users find their way around. In terms of usability, it reduces the number of actions a website visitor needs to take in order to get to a higher-level page.
It is also an effective visual aid that indicates the location of the user within the website's hierarchy, making it a great source of contextual information for landing pages.
