Breadcrumbs help your visitors find their way … home.
Breadcrumbs are a very handy way to help your site visitor see where they are at any given time. They work especially well with WordPress pages as pages can have a hierarchy. There are parent pages and then child pages or sub-page and then even grandchild pages or sub-sub pages and so on.
In WOO Canvas, you turn them on easily in the Canvas Theme Options –> General Settings –> Display Options. Check the box and you’re done.
There aren’t any deeper options (not on posts, only on pages, etc.), so it’s all or nothing. With some conditional CSS, I’m sure you could make some easy ways to hide it when you didn’t want it. But overall, it’s a great element to navigation especially if your site has tons of pages or just lots of content and your menu/navigation is already overloaded with links and drop-downs. Let the breadcrumbs do some of that heavy lifting.
