    Hreflang tags guide search engines to serve correct language/regional URL, avoiding duplicate content issues.

    A STARTING-POINT EXAMPLE

    Hypothetical standard operating procedure

    Adapt this example to your site, access, tools, and change process. It is our suggested procedure, informed by the sources below.

    1. Add <link rel="alternate" hreflang="xx" href="URL" /> tags in <head> of each page variant.
    2. Include references to all other language versions plus x-default fallback.
    3. Verify reciprocity so each version references all others.
    4. Use hreflang testing tools and Search Console reports to verify implementation.
    5. Fix detected errors before or shortly after launch.

    Watch for

    Missing or incorrect hreflang annotations cause wrong language versions to rank or duplicate indexing.

    Definition of done

    All language versions include reciprocal hreflang links referencing all variants including themselves and x-default.
