    // 如果slug太长,截断并添加ID
    if (baseSlug.length > 50 && id) {
      return `${baseSlug.substring(0, 47)}-${id}`
    }

    return baseSlug
  }

  // 分页URL结构

🛠️ SEO优化故障排除指南

常见问题解决方案

Meta标签重复问题

javascript
// 问题:页面Meta标签重复或冲突
// 解决:使用正确的优先级和覆盖机制

// ❌ 错误做法
useSeoMeta({ title: '默认标题' })  // 在layout中
useSeoMeta({ title: '页面标题' })  // 在page中,可能不生效

// ✅ 正确做法
// layout.vue
useSeoMeta({
  titleTemplate: '%s - 我的网站',  // 使用模板
  description: '默认描述'
})

// page.vue
useSeoMeta({
  title: '页面标题',  // 会自动应用模板
  description: '页面特定描述'  // 覆盖默认描述
})

结构化数据验证失败

javascript
// 问题:结构化数据格式错误
// 解决:使用Google结构化数据测试工具验证

// ❌ 错误格式
const structuredData = {
  '@context': 'https://schema.org',
  '@type': 'Article',
  headline: article.title,
  // 缺少必需字段
}

// ✅ 正确格式
const structuredData = {
  '@context': 'https://schema.org',
  '@type': 'Article',
  headline: article.title,
  author: {
    '@type': 'Person',
    name: article.author
  },
  datePublished: article.publishedAt,
