Google Search Uses Breadcrumb to Categorize the Information from the Page

Google Search Uses Breadcrumb to Categorize the Information from the Web Page or Blog.

A breadcrumb trail on a page indicates the page's position in the site hierarchy.

A user can navigate all the way up in the site hierarchy, one level at a time, by starting from the last breadcrumb in the breadcrumb trail.

Use Cases

Google Search uses breadcrumb markup in the body of a web page to categorize the information from the page in search results.

Often, as illustrated in following use cases, users can arrive at a page from very different types of search queries.

While each search may return the same web page, the breadcrumb categorizes the content within the context of the Google Search query.

The page ancillaryjustice.html might display the following breadcrumb trails depending upon the search context.
