Canonical URL
A canonical URL is the preferred version of a page when duplicate or near-duplicate versions exist (e.g. with/without trailing slash, query strings, mobile/desktop). Declared via `<link rel="canonical" href="...">` in the page head. Prevents SEO dilution.
More detail
Common duplicate scenarios that need canonicals: tracking URLs (?utm_source=...), pagination, AMP versions, mobile subdomain (m.example.com), HTTP vs HTTPS, www vs non-www. Aiprosol declares canonical on every page via Next.js metadata.alternates.canonical — points to the bare URL without query parameters.
