Deindexing

Deindexed means Google has removed a page or website from its search results, making it impossible for users to find through search. This can happen if you violate Google’s guidelines, use spammy tactics, or request removal through a noindex tag. While some deindexing is intentional (like for private pages), unwanted deindexing can seriously harm your website’s visibility and traffic.
