我最近将 RDFa 面包屑结构化数据添加到我们的网站之一。现在看起来它与网站上已经存在的开放图谱数据冲突。这怎么可能？OG 数据在<head>标签中，甚至不靠近面包屑。
见测试：https : //search.google.com/structured-data/testing-tool?hl=EN#url=https%3A%2F%2Fwww.badkamerwinkel.nl%2Fwastafels%2Fwastafel
网站网址：https : //www.badkamerwinkel.nl/wastafels/wastafel
在<head>标签中打开图代码：
<meta property="al:ios:url" content="badkamer://categories/79"/><meta property="al:ios:app_name" content="Badkamerwinkel"/><meta property="al:ios:app_store_id" content="1079403656"/><meta property="og:type" content="product.group" />
<meta property="og:title" content="Wastafel nodig? | Badkamerwinkel.nl" />
