看看Google提供的示例here,第一个面包屑似乎已经深了1级。
我是否正确地假设主页随后被确定为根域?如果它是子域怎么办?
上面链接中的示例代码,引用为:
{
"@context": "https://schema.org","@type": "BreadcrumbList","itemListElement": [{
"@type": "ListItem","position": 1,"name": "Books","item": "https://example.com/books"
},{
"@type": "ListItem","position": 2,"name": "Authors","item": "https://example.com/books/authors"
},"position": 3,"name": "Ann Leckie","item": "https://example.com/books/authors/annleckie"
}]
}
