Breadcrumb navigation, or breadcrumb trail, is an aid that allows website visitors to keep track of their location within the hierarchy of the website. The breadcrumb navigation is typically located horizontally across the top of a web page below the title and header of the page and include links back to the previous pages that the user has already visited in order to get to the current page that they are on. The breadcrumb navigation essentially leaves a trail of where the user has been in case they want to easily go back to a page previously visited without clicking the “back” button numerous times.
Breadcrumb navigation typically looks like this:
Homepage > Interior Page > Subsection of Interior Page
Homepage: Interior Page: Subsection of Interior Page
Including breadcrumb navigation on a website helps improve the usability of the website, which is a factor when visitors decide whether or not to make a purchase, convert in another way, or return at a later time.
