A good question for Matt Cutts is whether having multiple breadcrumbs on your site can confuse Googlebot. This question is from an E-commerce owner in Japan.

As ever with Google and Rankings etc, moderation is key. If you have a product that is in many categories and you have a list of 20 different breadcrumbs on your site. That’s probably a bit confusing. But again, if you have a product in a few categories and you only list one, that in turn won’t help Googlebot understand this product.

Breadcrumbs aren’t the sole factor in this as a proper structured website will also help this. So you don’t need to have every category your product is in on the website if your top menu is fixed. See the full video below:
