CANONICAL_URL_MISSING
Missing canonical URL
Synviber can fix this automatically for a connected domainWhat this check looks at
Whether a page declares a <link rel="canonical"> tag.
Why AI answer engines care
A canonical tag tells AI assistants and search engines the one authoritative URL for a piece of content, avoiding ambiguity when the same content is reachable at more than one URL.
Does Synviber fix it for me?
Yes, for a connected domain — the dashboard publishes the fix live at the gateway and re-scans to confirm it worked. Not available without a connected domain.
How to fix it manually
Low severity
Scanner message: "Page is missing a <link rel="canonical"> tag"
