// SEO
An HTML tag that tells search engines which version of a page is the 'official' one when duplicate or near-duplicate content exists at multiple URLs. Prevents duplicate content penalties and consolidates link equity.
Why it matters: Canonical URL is one of the seo signals that shapes how search engines, AI tools, and real visitors experience your website. Getting it right removes friction, protects your rankings, and makes every other optimization work harder. Auditing it regularly is the fastest way to catch regressions before they cost you traffic or conversions.
