We have a website with multiple product verticals which are independent sections (first section has sub-directory
example.com/section1, second one has
example.com/section2 and so on for other sections).
Would we face any issues if we were to add breadcrumbs to a particular section but not add them to the other sections from an SEO perspective? Would we get the benefit of Google being able to understand our page content and hierarchy better for the pages which do get breadcrumbs?
