On websites that have a lot of pages, breadcrumb navigation can greatly enhance the way users find their way around. In terms of usability, breadcrumbs reduce the number of actions a website visitor needs to take in order to get to a higher-level page, and they improve the findability of website sections and pages. They are 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.
