Show where a product sits in the catalog
A hierarchical breadcrumb describes the site structure, rather than reproducing every page a visitor clicked. The browser’s Back button follows browsing history; this kind of breadcrumb follows the catalog relationship. Other breadcrumb patterns can represent browsing history, so choose the pattern deliberately. A product reached from search should still have a meaningful route to its parent collection even when the visitor never opened that collection first.
Illustrative catalog trail: Home → Bags → Overnight bags → Canvas Weekender. The first three items link to their destinations; the product name identifies the current page. Someone arriving directly at the Weekender can select Overnight bags to compare capacity and materials. If the store groups it under Travel instead, the trail should follow that deliberate structure, not a temporary promotional campaign.
Link back to a useful parent collection
The trail is only useful if its parents exist and contain relevant choices. Breadcrumb structured data describes that relationship to search systems; it does not replace visible navigation or guarantee a particular search-result display.
Next, choose one product that appears in several collections. Agree the most useful hierarchy, test the visible parent links and check that any breadcrumb markup describes the same trail.
