Basic Concepts | Indexation
Direct Ranking Factor: Critical
As mentioned already, there are many responses or status codes a page can return when accessing it. If a page is inaccessible for any reason, such as the page returning an error, or redirecting the user, it will not be indexed by Google.
Pages that become inaccessible for any reason can also be deindexed by Google, meaning that they will be removed from Google’s index.
Regardless of the content, canonical tag, or robots tag, if a page is inaccessible; Google will not be able to see those components.
