Canonical URL
A canonical URL is the preferred "official" URL for a piece of content when multiple URLs could show similar or identical content.
Glossaries often create duplicates accidentally (case, trailing slash, query params). Canonicals protect authority and crawl budget.
Explanation
Canonicalization is implemented via canonical tags, redirects, and consistent internal linking. It helps search engines consolidate ranking signals and avoid duplicate indexing.
Marketing Relevance
Glossaries often create duplicates accidentally (case, trailing slash, query params). Canonicals protect authority and crawl budget.
Example
/glossary/prompt-engineering/ is canonical; variants with ?utm= or different casing point back to it.

Canonical tags pointing to non-equivalent pages, conflicting canonicals/redirects, not aligning sitemap + internal links to canonical.
