Schema.org的“类别”页面

Question

背景：我正在一家电子商务商店中，我们有一个类别页面，显示产品的缩略图，价格，名称和简短描述。无法从此页面购买，需要首先进入产品详细信息页面。

我对类别页面上schema.org的用法感到非常困惑。

提出了几种解决方案，但不能说出最好的（最好是最后一个）

1. ItemListListItems如https://developers.google.com/search/docs/guides/mark-up-listings上所建议的那样带有内部 （不支持产品，但是它显示了在网站上放置多个项目的想法）

   {
   "@context": "http://schema.org",
   "@type": "ItemList",
   "name": "T-Shirt",
   "url": "/category/t-shirt/",
   "description": "Deserunt quibusdam ipsa illo ex nam ea illo qui. Itaque maiores doloribus accusamus ratione. Aperiam ipsa veritatis quas nisi.",
   "itemListOrder": "Unordered",
   "numberOfItems": 2,
   "itemListElement": [
       {
           "@type": "ListItem",
           "position": 1,
           "url": "/products/lopez-smith-25/?color=yellow&size=XXL",
           "name": "Yellow Lopez-Smith",
           "image": {
               "@context": "http://schema.org",
               "@type": "ImageObject",
               "contentUrl": "/media/__sized__/products/yellow_n2QjKzn-thumbnail-640x640-70.jpg",
               "description": "Lopez-Smith",
               "width": 640,
               "height": 640
           }
       },
       {
           "@type": "ListItem",
           "position": 2,
           "url": "/products/lopez-smith-25/?color=blue&size=37",
           "name": "Blue Lopez-Smith",
           "image": {
               "@context": "http://schema.org",
               "@type": "ImageObject",
               "contentUrl": "/media/__sized__/products/blue_FZ3yJjG-thumbnail-640x640-70.jpg",
               "description": "Lopez-Smith",
               "width": 640,
               "height": 640
           }
       }
   ]
   }
   

   2. 推荐上几款产品作为https://developers.google.com/search/docs/guides/sd-policies 结合在一起使用@graph

一个类别页面，列出了几种不同的产品（或食谱，视频或任何其他类型）。每个实体都应使用相关的schema.org类型进行标记，例如产品类别页面的schema.org/Product。但是，如果标记了一项，则应标记所有项。另外，除非这是轮播页面，否则标记的项目不应链接到单独的详细信息页面。

{
    "@context": "http://schema.org",
    "@graph": [
        {
            "@type": "Product",
            "@id": "/category/t-shirt/p-1",
            "description": "Nobis vel fugiat e",
            "name": "Yellow Lopez-Smith",
            "offers": {
                "@type": "Offer",
                "availability": "http://schema.org/InStock",
                "price": "18.28",
                "priceCurrency": "GBP",
                "itemCondition": "http://schema.org/NewCondition",
                "description": "Nobis vel fugiat e",
                "name": "Yellow Lopez-Smith",
                "gtin13": "68614",
                "category": "T-Shirt",
                "image": {
                    "@context": "http://schema.org",
                    "@type": "ImageObject",
                    "contentUrl": "/media/__sized__/products/yellow_n2QjKzn-thumbnail-640x640-70.jpg",
                    "description": "Lopez-Smith",
                    "width": 640,
                    "height": 640
                }
            }
        },
        {
            "@type": "Product",
            "@id": "/category/t-shirt/p-2",
            "description": "Nobis vel fugiat e",
            "name": "Blue Lopez-Smith",
            "offers": {
                "@type": "Offer",
                "availability": "http://schema.org/InStock",
                "price": "22.64",
                "priceCurrency": "GBP",
                "itemCondition": "http://schema.org/NewCondition",
                "description": "Nobis vel fugiat e",
                "name": "Blue Lopez-Smith",
                "gtin13": "73963",
                "category": "T-Shirt",
                "image": {
                    "@context": "http://schema.org",
                    "@type": "ImageObject",
                    "contentUrl": "/media/__sized__/products/blue_FZ3yJjG-thumbnail-640x640-70.jpg",
                    "description": "Lopez-Smith",
                    "width": 640,
                    "height": 640
                }
            }
        }
    ]
}

3. Products列为不同ItemOffered的内容Offer（基于Ebay）

   {
   "@context": "http://schema.org",
   "@type": "WebPageElement",
   "offers": {
       "@type": "Offer",
       "itemOffered": [
           {
               "@type": "Product",
               "@id": "/category/t-shirt/p-1",
               "description": "Nobis vel fugiat e",
               "name": "Yellow Lopez-Smith",
               "offers": {
                   "@type": "Offer",
                   "availability": "http://schema.org/InStock",
                   "price": "18.28",
                   "priceCurrency": "GBP",
                   "itemCondition": "http://schema.org/NewCondition",
                   "description": "Nobis vel fugiat e",
                   "name": "Yellow Lopez-Smith",
                   "gtin13": "68614",
                   "category": "T-Shirt",
                   "image": {
                       "@context": "http://schema.org",
                       "@type": "ImageObject",
                       "contentUrl": "/media/__sized__/products/yellow_n2QjKzn-thumbnail-640x640-70.jpg",
                       "description": "Lopez-Smith",
                       "width": 640,
                       "height": 640
                   }
               }
           },
           {
               "@type": "Product",
               "@id": "/category/t-shirt/p-2",
               "description": "Nobis vel fugiat e",
               "name": "Blue Lopez-Smith",
               "offers": {
                   "@type": "Offer",
                   "availability": "http://schema.org/InStock",
                   "price": "22.64",
                   "priceCurrency": "GBP",
                   "itemCondition": "http://schema.org/NewCondition",
                   "description": "Nobis vel fugiat e",
                   "name": "Blue Lopez-Smith",
                   "gtin13": "73963",
                   "category": "T-Shirt",
                   "image": {
                       "@context": "http://schema.org",
                       "@type": "ImageObject",
                       "contentUrl": "/media/__sized__/products/blue_FZ3yJjG-thumbnail-640x640-70.jpg",
                       "description": "Lopez-Smith",
                       "width": 640,
                       "height": 640
                   }
               }
               }
           ]
       }
   }
