Breadcrumbs are a small navigation trail, usually a thin row of links near the top of a page, that shows where the current page sits within the wider site. A typical trail reads something like Home > Laptops > Gaming > this model, and every step before the last one is clickable, so a visitor can jump back up a level in a single tap.
The name comes from the Hansel and Gretel fairy tale, where the children drop breadcrumbs to find their way home. On a website they do the same job: they tell you how deep you have wandered and offer a clear route back out. This matters most on big sites like webshops, where someone arriving from a Google search might land three or four levels deep with no idea of the structure above them. Good breadcrumbs lean on a logical URL structure and add to the overall navigation without crowding the page.
There is a craft to keeping them honest. A breadcrumb should reflect the real path through the site, not a made-up one, and the current page is shown but not linked to itself. Each step is just an internal link, so the trail doubles as a quiet way to spread link value to your category pages.
They quietly help search engines too. Google can read the trail to understand how your sections relate, and it sometimes shows breadcrumbs directly in the search results instead of a raw web address, which can make a listing easier to scan.
At TopDevs we add breadcrumbs to deep, multi-level sites so visitors always know where they are, and so search engines get a clean map of how the pages fit together.
