FAQ
What does a canonical tag do?
It signals the preferred version of similar or duplicate content so search engines can consolidate indexing and ranking signals.
Can canonical fix every duplicate URL issue?
No. It is a signal, not a command. Redirects, internal links, and sitemap URLs should also point to the preferred version.
Should canonical URLs be absolute?
Absolute HTTPS URLs are safer because they remove ambiguity across environments and mirrors.
How does canonical work with hreflang?
Each language page should normally canonicalize to itself and link alternate language versions with hreflang.
