❓ Frequently Asked Questions
Common questions about Canonical URL Validator
What is canonical URL?▼
Tag declaring the official URL when same content exists at multiple URLs. Prevents duplicate content issues.
Free validator?▼
Yes, 100% free. Check canonical implementation. Detect issues and conflicts.
Why use canonical?▼
Same content can appear at multiple URLs (www/non-www, http/https, with/without trailing slash). Tells Google which is primary.
Self-canonical?▼
Yes, every page should have canonical (even if pointing to itself). Prevents future duplicate issues.
Canonical syntax?▼
link rel canonical href your URL in head. Absolute URL, not relative.
Common mistakes?▼
Wrong protocol (http when site is https), pointing to non-existent pages, multiple canonicals on one page, conflicting with redirects.
Canonical vs 301?▼
301: server-side redirect. Canonical: tag suggesting primary. Use 301 when possible. Canonical for cases where URLs must coexist.
Cross-domain canonical?▼
Yes, valid. Useful for syndicated content. Original site canonical + republisher canonical to original.
