Hreflang

Hreflang annotations identify alternate language or regional versions of equivalent pages.

In plain English

Hreflang helps Google serve the appropriate localized URL. It does not translate content, target Bing, replace canonicals or guarantee a particular result.

01

Why does Hreflang matter?

International sites can otherwise show the wrong country or language page.

Broken return links, invalid codes and non-canonical destinations can invalidate an entire cluster.

02

How does Hreflang work?

  1. Create a cluster

    Every equivalent page lists itself and all alternates using supported language-region codes.

  2. Return annotations

    Each alternate must link back to the others.

  3. Use x-default

    Optionally specify a fallback selector or default page.

  4. Serve localized content

    Language, currency, offers and internal links should genuinely fit the market.

03

A practical Hreflang example

Scenario

A service has English-India and English-Philippines versions with distinct offers.

Interpretation

Each canonical 200 page can reference en-IN and en-PH alternates plus x-default, with reciprocal annotations.

04

Common mistakes and misconceptions

  1. Using country without language

    Hreflang begins with a supported language code; country is optional.

  2. Pointing to redirects

    Annotations should resolve to canonical indexable URLs.

  3. Replacing localization with tags

    Annotations cannot make translated boilerplate useful to a market.

How to use Hreflang in practice

  1. 1
    Map equivalent owners

    Include only pages that fulfil the same task in another locale.

  2. 2
    Generate reciprocal clusters

    Use HTML, HTTP headers or XML sitemaps consistently.

  3. 3
    Validate codes and destinations

    Test return links, canonical state, status and rendered annotations.

06

How should Hreflang be measured?

  • Valid reciprocal clusters.
  • Wrong-locale landings and country performance.
  • Canonical/hreflang conflicts.
  • Localized conversions by page.

FAQ

Questions about Hreflang

Its job is locale selection, not an automatic ranking boost.
Bing has historically relied more on language and geo signals such as content and meta language; verify its current documentation for your implementation.
No, but it is useful for an unmatched-language selector or fallback page.
