# `PhoenixKitEcommerce.Web.SEOHelpers`
[🔗](https://github.com/BeamLabEU/phoenix_kit_ecommerce/blob/0.5.10/lib/phoenix_kit_ecommerce/web/seo_helpers.ex#L1)

Catalog SEO assigns (canonical / hreflang / og) for the public shop
LiveViews, multi-domain aware.

The canonical host per language comes from the workspace-wide
`config :phoenix_kit, :canonical_host_resolver, {mod, fun}` MFA (nil or
absent ⇒ the site-wide `PhoenixKit.Utils.Routes.url/1` base, today's
behavior). On a language's home host its own locale prefix is stripped —
the language is that domain's default.

hreflang inclusion for slug-translated pages is decided on the RAW slug
map (`Map.has_key?(entity.slug, lang)`) — `SlugResolver` silently falls
back to the default-language slug, which must never produce an hreflang
entry mislabelling the fallback URL as a translation.
