Two or more blocks of content are equivalent if their content serves the same purpose and cover equally well the expectation of the user navigating to them. This usually involves that the key content is the same.
Web pages and documents (e.g. PDFs, office formats etc.) may contain equivalent content, even if the content:
- presents different navigation options, e.g. through bread crumbs or local sub menus; or
- contains different amounts of information and/or differently worded information; or
- uses different layouts.
