      "label": "Lazy-load the calculator",
      "source_url": "https://sellerfeecalc.com/embed",
      "recommendation": "Use the lazy iframe or async script snippet so article text, headings, and source links render before the calculator loads.",
      "publisher_benefit": "Keeps the article readable on slower mobile connections while still giving readers an interactive fee calculator."

      "label": "Reserve widget height",
      "source_url": "https://sellerfeecalc.com/publisher-embed-snippets.json",
      "recommendation": "Reserve at least 720px of height for platform-specific embeds and 760px for the all-marketplace embed to avoid layout shifts.",
      "publisher_benefit": "Reduces cumulative layout shift risk when the calculator appears below fee examples or comparison tables."

      "label": "Keep FlipCalc attribution visible",
      "source_url": "https://sellerfeecalc.com/about/methodology",
      "recommendation": "Keep the visible FlipCalc attribution and methodology link near the widget so readers can verify fee assumptions.",
      "publisher_benefit": "Gives editors and readers a clear source path without adding affiliate redirects, sign-up walls, or paid ranking claims."

      "label": "Pair source links with the widget",
      "source_url": "https://sellerfeecalc.com/fee-index",
      "recommendation": "Place the Fee Index, Fee Changes, or report citation before the widget, then embed the calculator where readers need to test their own price.",
      "publisher_benefit": "Turns static fee claims into a verifiable source plus an interactive reader action."
