Don't expect to learn a new recipe. These breadcrumbs are different from what you think when you imagine mouth-watering meals. Jakob Nielson would further elucidate you about the matter...

Breadcrumbs have always been a secondary navigation aid. While secondary, this navigation technique is increasingly beneficial to users.

Breadcrumbs won't help a site answer users' questions or fix a hopelessly confused information architecture. All that breadcrumbs do is make it easier for users to move around the site, assuming its content and overall structure make sense. That's sufficient contribution for something that takes up only one line in the design.

Breadcrumbs have always been a secondary navigation aid. Despite their secondary status, I've recommended breadcrumbs since 1995 for a few simple reasons:

* Breadcrumbs show people their current location relative to higher-level concepts, helping them understand where they are in relation to the rest of the site.
* Breadcrumbs afford one-click access to higher site levels and thus rescue users who parachute into very specific but inappropriate destinations through search or deep links.
* Breadcrumbs never cause problems in user testing: people might overlook this small design element, but they never misinterpret breadcrumb trails or have trouble operating them.
* Breadcrumbs take up very little space on the page.

If your website, for one reason or the other, have no breadcrumbs, it's time to start now. They could help you attain ideal web traffic and top search engine rankings.
