在单个页面上包含多个产品的多个类别

Question

我的目标是基于this正确输出JSON-D。问题在于该网站具有多个类别，这些类别在一个页面上包含多个产品。该网站的结构如下：

Amarelo K

• Amarelo K 101
• Amarelo K 102
• Amerelo K 103

Amarelo D

• Amarelo D 101
• Amarelo D 102
• Amerelo D 103

Amarelo C

• Amarelo C 101
• Amarelo C 102
• Amerelo C 103

我认为我可以使用这样的东西

            }
          ]
        }
      },

          "itemListElement": [
            {

              "image": ["LinkToTheProduct101Img"],
              "url": "LinkToTheProduct#101"
            },
            {
              "@type": "Product",
              "name": "Amarelo C 102",
              "image": ["LinkToTheProduct102Img"],
              "url": "LinkToTheProduct#102"
            },
            {
              "@type": "Product",
              "name": "Amarelo C 103",
              "image": ["LinkToTheProduct103Img"],
              "url": "LinkToTheProduct#103"
            }
          ]
        }
      }
    ]
  }
}

它甚至成功通过了Google Structured Data Testing Tool，但我想知道我是否没有错过任何事情...
