Hreflang

An annotation that connects language/region variants of equivalent pages so the right version is served to the right users.

Definition

Hreflang tags indicate the language and optional region of alternate versions of the same content. They matter because they reduce wrong‑language impressions and consolidate signals across variants. Proper implementation requires reciprocal annotations among all alternates and an optional x‑default for a global fallback. Hreflang influences URL strategy, sitemaps, and CMS templates for international sites.

What matters
  • Add reciprocal links among alternates
  • Consider x‑default for global pages
How it plays out
  1. Context

  2. Action

    Each page references all alternates and includes self‑referencing hreflang.

  3. Result

    Users see language‑appropriate pages; duplicate ambiguity decreases across markets.
