## Frequently Asked Questions

Everything you need to know about our free SEO tools

### What is a canonical tag?

A canonical tag (rel=canonical) tells search engines which version of a page is the 'original'. It prevents duplicate content penalties when similar pages exist.

### Should every page have a canonical tag?

Yes. Every indexable page should have a self-referencing canonical tag. This is considered an SEO best practice even if no duplicates exist.

### What happens if canonical is missing?

Without a canonical tag, search engines must guess which version of a page to index. This can lead to diluted ranking signals and duplicate content issues.

### Can canonical tags hurt SEO?

Yes, if misconfigured. Pointing a canonical to the wrong URL can cause Google to ignore your preferred page entirely.

### What is the difference between canonical and redirect?

A canonical is a suggestion to search engines, while a 301 redirect physically moves users and bots. Use redirects for permanent URL changes and canonicals for duplicate content.
