Preface: I do not have full edit capabilities of my websites. I am a part of a bureaucracy and have limited access.
Question: So, for pages that I don't have access to - meaning I cannot edit the meta data, they have no content, and they are listed in the sitemap - rather than requesting that a noindex tag be placed, if I request that a canonical tag be placed instead, to point to the home page, will I be passing along whatever "link juice" those pages have to the home page, without passing along the default and detrimental meta data they have?
In other words, these pages, as they exist, are harmful to the site's SEO. I can't access them from the backend either. But I can request the website providers place html code in the head.
Is it better to tell Google just don;t index these pages, or should I use canonical tags, and pass along whatever link power they might have to the home page? Will that also pass along the detrimental state of their meta data, which I cannot edit?
