Frequently Asked Questions
What does a canonical tag do?
It tells search engines which URL is the master copy when similar content exists at multiple addresses, so ranking signals are not split across duplicates.
Should every page have a canonical tag?
Yes — even pages without duplicates benefit, because it guards against URL variations like tracking parameters creating accidental copies.
