下面的代码包含两个还是一个结构化数据？我可以使用架构类型“产品组”和“hasVariant”编写代码吗，因为“SS钢丝绳”、“PVC涂层钢丝绳”和其他都是钢丝绳类型。我的代码是对还是错？可以应用在网页上吗

我正在尝试为产品“钢丝绳”编写 JSON-LD 格式的模式标记。不锈钢钢丝绳、镀锌钢丝绳和未镀锌钢丝绳是钢丝绳的类型
我不知道有任何结构化数据消费者正式支持产品变体的想法。
Google 和 Schema.org 一直在讨论如何最好地支持它，但目前还没有任何实质性进展。
Schema.org github 存储库中有一个关于它的长对话：
https://github.com/schemaorg/schemaorg/issues/1797
如果我们将您当前的代码放入 Google Rich Result Tester 中，您会发现 Google 忽略了除您的第一个产品之外的所有产品。
此时，我建议您每页只添加一个产品，因为这是 Google 等消费者目前支持的。
