Rel Canonical
An HTML element that specifies the preferred version of a webpage to prevent duplicate content issues
The rel canonical tag is an HTML link element that tells search engines which version of a page should be considered the primary or authoritative copy. This is particularly useful when similar or duplicate content exists across multiple URLs. For link building, canonical tags matter because backlinks pointing to non-canonical URLs may have their equity consolidated to the canonical version. When acquiring links, ensure they point to the canonical URL to maximize SEO impact. Similarly, when auditing your link profile, check that your most-linked pages have proper canonical tags to ensure link equity is directed where you intend.
