    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. Identify hero images and critical CSS/JS assets affecting LCP.
    2. Add <link rel="preload"> tags with correct 'as' attributes in page head.
    3. Verify HTTP/2 server push as applicable to further speed delivery.

    5. Monitor Core Web Vitals metrics to confirm improvements.
