In-depth guide
A canonical tag (<link rel="canonical">) tells search engines which URL is the master version when the same or very similar content is reachable at several addresses. It consolidates ranking signals onto one page instead of splitting them across duplicates. This tool builds the tag for you in the browser — paste a URL, copy the markup.
Duplicate URLs are everywhere: tracking parameters (?utm_source=), session IDs, http vs https, trailing slashes, and printer-friendly views. Without guidance, Google may index the wrong variant or dilute your authority across all of them. A canonical points every duplicate at the single URL you want ranked.
https:// and the exact host).<link rel="canonical"> tag.<head> of every duplicate page, pointing at this same target.A page can and usually should canonicalise to itself — a self-referencing canonical removes ambiguity around parameters. Always point at the final destination: never canonicalise to a URL that then redirects, and make sure the target returns HTTP 200, is crawlable, and is not blocked by robots rules.
Use this tool for quick browser-based work when you need an answer or output immediately. Use a dedicated application or automated workflow when you need bulk processing, approvals, or repeatable production rules.
Use one whenever the same or very similar content is reachable at more than one URL — tracking parameters, http/https variants, trailing slashes, or printer views — and you want a single preferred URL to be indexed.
Yes, and it is recommended best practice. A page pointing its canonical at itself removes ambiguity around URL parameters and is the cleanest default.
No. Always point at the final destination that returns HTTP 200. Canonicalising to a URL that then redirects sends a conflicting signal and may be ignored.
It is a strong hint, not a directive. Google usually honours it, but conflicting signals — such as a noindex on the target or canonical loops — will cause it to be disregarded.
No. Multiple canonical tags cancel each other out and Google treats them as if none were specified. Use exactly one per page.
Relative URLs are technically allowed, but absolute URLs (including https and the exact host) avoid host ambiguity and are strongly recommended.
