📝 核心要点（Takeaways）

• Schema标记是CTR杠杆：富媒体摘要可使搜索结果点击率提升35%-50%，ROI显著高于纯内容优化
• 电商五件套必装：Product、Offer、Review、BreadcrumbList、Organization是电商站点的Schema优先级清单
• JSON-LD是唯一推荐格式：Google官方推荐，实现简单且与HTML解耦，避免Microdata和RDFa
• 验证是上线必经步骤：所有Schema标记必须通过Rich Results Test和Schema Markup Validator双重验证
• 合规红线不可碰：严禁虚构评价数据，ratingValue和reviewCount必须与页面实际展示一致

1. 使用Google Rich Results Test扫描现有产品页，识别缺失的Schema类型
2. 根据本文代码模板，为首页添加Organization Schema，为产品页添加Product+Offer+Review组合
3. 在Google Search Console「增强功能」报告中监控富媒体摘要展示数据
4. 制定Schema维护SOP，确保新品上架时自动触发Schema标记生成
