很多人有时候会碰到百度不收录文章缩略图，想让自己在百度搜索结果里出现缩略图的情况。除了我们从百度上搜索到的，针对图片大小，alt标签的完善，其实还有一个办法，能帮助我们。

数据化JSON-LD结构代码

其实谷歌很早就已经在使用schema代码，来展示结构化数据，而百度则是18年跟随熊掌号才开始使用，20年初熊掌号已经彻底落幕，但是这段代码其实仍然可以使用。

百度JSON-LD格式示例：

<script  type="application/ld+json"> {

       "@context": "https://zhanzhang.baidu.com/contexts/cambrian.jsonld",

       "@id": "https://zhanzhang.baidu.com/",

       "title":"百度站长平台_让网站更具价值",

       "images": [

           "https://ss0.bdstatic.com/5aV1bjqh_Q23odCf/static/superman/img/logo/bd_logo1_31bdc765.png",

           "https://ss0.bdstatic.com/5aV1bjqh_Q23odCf/static/superman/img/logo_top_ca79a146.png",

           "https://m.baidu.com/static/index/plus/plus_logo.png"

       ],

       "description": "全球最大的面向中文互联网管理者、移动开发者、创业者的搜索流量管理的官方平台。提供有助于搜索引擎收录的工具、SEO建议、API接口、多端适配服务的能力等。",

       "pubDate": "2017-06-06T08:00:01",

       "isOriginal": "0"

}</script>

具体的使用规范可见《百度搜索落地页时间因子规范》

熊掌号既然已经不在，熊掌号ID可以选择不填。

下面可以看看谷歌的schema代码，一般谷歌对于收录速度和样式展现还是比较符合预期的，所以基本没有怎么用过。

谷歌JSON-LD格式示例：

<script type="application/ld+json">

  "@context": "https://schema.org/",
  "@type": "Product",
