Add additional breadcrumbs links to Product Page.
If customers go to product page via current url-link, via browser or via search (Google, Yahoo), or search in Magento – customer will see short breadcrumbs. Like “Home->Product Name”. This normal.
But in Search systems (like Google) – will not show breadcrumbs for product page.
The module Breadcrumbs for Product page – will help with breadcrumbs for Product. Now in Google search result will show breadcrumbs for Product, of course if product has categories and not blocked it.
So, with extension Breadcrumbs for Product page – will breadcrumbs like “Home->Category1->Category2->Product Name”
