Good to know
A canonical tag answers one question for search engines: when several URLs serve the same content, which one is the master? The classic culprits are tracking parameters (?utm_source=…), session IDs, faceted-filter combinations, and the trailing-slash or www-versus-bare-domain variants that quietly create duplicates. Consolidating them onto one canonical URL concentrates ranking signals instead of splitting them.
Best practice is a self-referencing canonical on every indexable page — the URL pointing at itself in its clean, parameter-free form. This is defensive: it neutralizes any stray parameterized version a link or crawler might invent. Always use the absolute URL with the correct scheme, and pick one trailing-slash convention and stick to it, because /page and /page/ are distinct URLs to a crawler.
Remember the tag is a hint, not a command. Google can override it if other signals — internal links, the sitemap, redirects — point somewhere else. So keep every signal consistent: the canonical, the URL you list in your sitemap, and your internal links should all agree.
Don't canonicalize a page to a completely different one hoping to pass its equity along; that's what a 301 redirect is for. Canonical is strictly for near-duplicates of the same content, not for merging unrelated pages.
Frequently asked questions
- Is the canonical tag generator free?
- Yes — free with no signup.
- What does canonical do?
- It tells search engines which URL is the master version when multiple URLs serve the same content (e.g. /page vs /page?utm=).
- Should it be self-referencing?
- Yes — it's best practice for every indexable page to point its canonical at itself.
- Is anything uploaded?
- No — every tag is generated in your browser.
- Will Google always honor canonical?
- Canonical is a hint, not a directive. Google may still index the duplicate if it has stronger signals (more inbound links, etc.).
