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”
