    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. Use a hreflang testing tool to check at least five representative pages.
    2. Confirm each language page includes hreflang links to all other language URLs and to itself.
    3. Ensure the x-default hreflang tag points to a sensible fallback language page.
    4. Validate hreflang presence in page <head> section, not just in sitemap or HTTP headers, for best reliability.
    5. Address any errors or mismatches before launch for accurate indexing.

    Watch for

    Missing or improper hreflang tags can cause indexing mistakes and poor rankings in target languages.

    Definition of done

    All language pages reference every other language and themselves with correct hreflang tags, including an x-default fallback.
