使用语义化标签、Schema结构化数据、优化元信息、延迟加载资源及生成静态快照，可实现HTML代码演示的SEO友好嵌入。
如果您希望在网页上嵌入可运行的HTML代码演示，同时提升页面在搜索引擎中的可见性，就需要兼顾代码功能与SEO友好性。以下是实现这一目标的具体方法：
一、使用语义化标签包裹代码区域
通过语义化HTML标签对代码块进行结构化标记，有助于搜索引擎理解内容主题。合理使用
和标签不仅能保留格式，还能增强内容可读性。1、将可执行代码放入
结构中。...2、为每个代码示例添加
和标签，并描述其功能，例如：创建一个响应式按钮组件。立即学习“前端免费学习笔记（深入）”；
3、确保所有代码容器具有唯一的
id属性，便于锚点链接和JavaScript调用。二、为动态代码编辑器添加Schema结构化数据
结构化数据帮助搜索引擎识别页面上的交互式元素，如代码编辑器或实时预览窗口，从而可能触发富媒体搜索结果。
1、在页面
中插入JSON-LD脚本，声明内容类型为SoftwareSourceCode。2、填写关键字段，包括
name（示例名称）、description（功能说明）、programmingLanguage（HTML/CSS/JS）。3、标注
executable为true，并指定运行环境为浏览器端，以表明该代码可在客户端执行。三、优化代码演示页的元信息与标题结构
准确描述代码功能的标题和元描述能显著提高点击率，同时让爬虫更清晰地索引内容。
