What is breadcrumb navigation in web design?

Breadcrumb navigation, also known as a breadcrumb trail, is a navigation aid on websites that gives a structured overview of how a site is built and shows which path a user has taken within the website hierarchy. This kind of navigation is named after the fairy tale Hansel and Gretel, in which the main characters scatter breadcrumbs to find their way back home.

On a website, breadcrumbs usually appear at the top of a page, below the primary navigation elements. They present a path from the home page to the current page, and every level of that path is a clickable internal link, so visitors can switch to that level in one step. The form is often the following one, although the separator can vary:

Home > Category > Subpage

The advantages of breadcrumb navigation on the web

Breadcrumbs bring several advantages. They improve the usability of a website by helping users understand their position on the site and navigate efficiently. That is particularly helpful on websites with many levels or a complex structure, such as online stores or information portals.

Because they show the path a visitor has taken clearly, they make it possible to return to parent categories or to the home page without detours. Breadcrumbs reduce the number of clicks needed to reach a particular page and improve the user experience along the way. They can also keep visitors on a website longer, because related topics or products become easy to discover.

How breadcrumbs affect SEO

When it comes to search engine optimization (SEO), breadcrumbs have an important function as well. They help structure the content and make the website hierarchy clear to users and to search engines alike. Because breadcrumbs are often rich in keywords and mirror the topical structure of a site, they let website owners reinforce the relevance of their pages for particular search terms. That can help improve the rankings of a website in the search results.

Beyond that, breadcrumbs help search engines understand the structure of a website and index the content accordingly. That pays off above all on large websites with many pages. Breadcrumbs can also be shown in the search results, which increases the visibility of a website and potentially improves the click-through rate (CTR), because users can go straight to subordinate pages. Google itself has acknowledged how much breadcrumbs matter for SEO and shows them in the search results as part of the rich snippet, which gives users a better sense of where a page sits in the context of the whole website.

It is fair to say that breadcrumbs are a valuable addition to any website. They not only serve usability by making navigation simpler, they also play a strategic role in SEO, because they help structure the content and improve the findability of pages. In web design built for search engines they are therefore a standard element, and the SEO glossary explains the terms that connect to them.
