Schema Markup

Schema标记

  • Identify missing opportunities
  • NEVER recommend HowTo (deprecated) or FAQ (restricted to gov/health)
  • 检测所有类型(优先识别JSON-LD格式)
  • 验证必填属性
  • 识别缺失的优化机会
  • 绝不推荐使用HowTo(已废弃)或FAQ(仅限政府/医疗领域使用)类型

Images

图片

  • Alt text: present, descriptive, includes keywords where natural
  • File size: flag >200KB (warning), >500KB (critical)
  • Format: recommend WebP/AVIF over JPEG/PNG
  • Dimensions: width/height set for CLS prevention
  • Lazy loading: loading="lazy" on below-fold images
  • Alt text:存在,描述性强,自然融入关键词
  • 文件大小:大于200KB标记为警告,大于500KB标记为严重
  • 格式:推荐使用WebP/AVIF格式,替代JPEG/PNG
  • 尺寸:设置宽高以避免CLS问题
  • 懒加载:对首屏以下图片使用loading="lazy"属性

Core Web Vitals (reference only — not measurable from HTML alone)

核心Web指标(仅作参考——无法仅通过HTML测量)

  • Flag potential LCP issues (huge hero images, render-blocking resources)
  • Flag potential INP issues (heavy JS, no async/defer)
  • Flag potential CLS issues (missing image dimensions, injected content)
  • 标记潜在LCP问题(超大首图、阻塞渲染资源)
  • 标记潜在INP问题(重型JS、未使用async/defer)
  • 标记潜在CLS问题(缺失图片尺寸、注入式内容)
