评论系统优化

评论结构化标记

使用 Schema.org 标记评论，便于搜索引擎理解：

<article itemscope itemtype="https://schema.org/Product">
  <h1 itemprop="name">智能蓝牙耳机</h1>
  
  <!-- 商品评分汇总 -->
  <div itemprop="aggregateRating" itemscope itemtype="https://schema.org/AggregateRating">
    <span itemprop="ratingValue">4.5</span> / 
    <span itemprop="bestRating">5</span> 星
    （基于 <span itemprop="reviewCount">128</span> 条评价）
  </div>
  
  <!-- 用户评论 -->
  <section class="reviews">
    <h2>用户评价</h2>
    
    <div itemprop="review" itemscope itemtype="https://schema.org/Review">
      <div itemprop="author" itemscope itemtype="https://schema.org/Person">
        <span itemprop="name">张三</span>
      </div>
      
      <div itemprop="reviewRating" itemscope itemtype="https://schema.org/Rating">
        <span itemprop="ratingValue">5</span> / 
        <span itemprop="bestRating">5</span> 星
      </div>
      
      <time itemprop="datePublished" datetime="2025-12-15">2025年12月15日</time>
      
      <p itemprop="reviewBody">
        音质非常棒，降噪效果出色。佩戴舒适，续航也很给力，
        连续使用了6个小时还有电。推荐购买！
      </p>
    </div>
    
    <div itemprop="review" itemscope itemtype="https://schema.org/Review">
      <!-- 更多评论 -->
    </div>
  </section>
</article>

问答 SEO 最佳实践

社区内容策略

论坛帖子优化

// 帖子 SEO 优化服务
class ForumPostSEOService {
  // 生成帖子的 SEO 元数据
  generateMeta(post: ForumPost): SEOMeta {
    return {
      title: this.generateTitle(post),
      description: this.generateDescription(post),
      canonical: this.getCanonicalUrl(post),
      structuredData: this.generateDiscussionSchema(post)
    }
  }
  
  // 标题优化：包含主题关键词
  private generateTitle(post: ForumPost): string {
    const base = post.title.slice(0, 60)
    const category = post.category.name
    return `${base} - ${category} | 社区讨论`
  }
  
  // 描述优化：提取帖子核心内容
  private generateDescription(post: ForumPost): string {
    // 去除 HTML 标签
    const plainText = stripHtml(post.content)
    
    // 提取前 160 字符
    const description = plainText.slice(0, 160)
    
    // 添加互动数据增加吸引力
    return `${description}... (${post.replyCount} 回复, ${post.viewCount} 浏览)`
  }
  
  // 生成 DiscussionForumPosting Schema
  private generateDiscussionSchema(post: ForumPost): object {
    return {
      '@context': 'https://schema.org',
      '@type': 'DiscussionForumPosting',
      headline: post.title,
      text: stripHtml(post.content).slice(0, 1000),
      author: {
        '@type': 'Person',
        name: post.author.name,
        url: post.author.profileUrl
      },
      datePublished: post.createdAt.toISOString(),
      dateModified: post.updatedAt.toISOString(),
      interactionStatistic: [
        {
          '@type': 'InteractionCounter',
          interactionType: 'https://schema.org/CommentAction',
          userInteractionCount: post.replyCount
        },
        {
          '@type': 'InteractionCounter',
          interactionType: 'https://schema.org/LikeAction',
          userInteractionCount: post.likeCount
        }
      ],
      comment: post.replies.slice(0, 5).map(reply => ({

        text: stripHtml(reply.content).slice(0, 200),
        author: {
          '@type': 'Person',
          name: reply.author.name
        },
        dateCreated: reply.createdAt.toISOString()
      }))
    }
  }
  
  // 处理分页帖子的规范化 URL
  private getCanonicalUrl(post: ForumPost): string {
    // 所有分页都指向第一页作为规范 URL
    return `https://example.com/forum/post/${post.id}`
  }
}

用户内容激励机制

// 用户贡献积分系统
interface ContributionReward {
  action: string
  points: number
  dailyLimit?: number
  requirements?: string[]
}

const rewardConfig: ContributionReward[] = [
  // 评论相关
  { action: 'write_review', points: 10, dailyLimit: 3 },
  { action: 'review_with_images', points: 15, dailyLimit: 3 },
  { action: 'review_helpful_marked', points: 5 },
  
  // 问答相关
  { action: 'ask_question', points: 2, dailyLimit: 5 },
  { action: 'answer_question', points: 5, dailyLimit: 10 },
  { action: 'answer_accepted', points: 20 },
  
  // 论坛相关
  { action: 'create_post', points: 5, dailyLimit: 3 },
  { action: 'quality_post', points: 30, requirements: ['min_words:500', 'has_images'] },
  { action: 'post_liked', points: 1, dailyLimit: 50 },
  
  // 特殊贡献
  { action: 'first_review', points: 50 },
  { action: 'featured_content', points: 100 }
]

class ContributionService {
  async rewardUser(userId: string, action: string, context?: any) {
    const reward = rewardConfig.find(r => r.action === action)
    if (!reward) return
    
    // 检查每日限制
    if (reward.dailyLimit) {
      const todayCount = await this.getTodayActionCount(userId, action)
      if (todayCount >= reward.dailyLimit) return
    }
    
    // 检查特殊要求
    if (reward.requirements) {
      const passed = await this.checkRequirements(context, reward.requirements)
      if (!passed) return
    }
    
    // 发放积分
    await this.addPoints(userId, reward.points, action)
    
    // 发送通知
    await this.notifyUser(userId, {
      type: 'points_earned',
      message: `您获得了 ${reward.points} 积分`,
      action
    })
  }
}

内容审核策略

多级审核机制

// 内容审核服务
class ContentModerationService {
  private aiModerator: AIModerationService
  private humanQueue: ModerationQueue
  
  async moderateContent(content: UserContent): Promise<ModerationResult> {
    // 第一级：自动过滤敏感词
    const sensitiveCheck = await this.checkSensitiveWords(content.text)
    if (sensitiveCheck.blocked) {
      return {
        status: 'rejected',
        reason: sensitiveCheck.reason,
        level: 'auto'
      }
    }
    
    // 第二级：AI 内容分析
    const aiAnalysis = await this.aiModerator.analyze(content)
    
    if (aiAnalysis.toxicityScore > 0.9) {
      // 高风险内容直接拒绝
      return {
        status: 'rejected',
        reason: '内容可能包含违规信息',
        level: 'ai'
      }
    }
    
    if (aiAnalysis.toxicityScore > 0.5) {
      // 中等风险进入人工审核
      await this.humanQueue.add({
        content,
        aiAnalysis,
        priority: 'high'
      })
      
      return {
        status: 'pending',
        reason: '内容正在审核中',
        level: 'human'
      }
    }
    
    // 第三级：垃圾内容检测
    const spamCheck = await this.checkSpam(content)
    if (spamCheck.isSpam) {
      return {
        status: 'rejected',
        reason: '内容被识别为垃圾信息',
        level: 'spam'
      }
    }
    
    // 第四级：质量评估
    const qualityScore = await this.assessQuality(content)
    
    return {
      status: 'approved',
      qualityScore,
      level: 'auto'
    }
  }
  
  // 内容质量评估
  private async assessQuality(content: UserContent): Promise<number> {
    let score = 50  // 基础分
    
    // 内容长度加分
    const wordCount = content.text.split(/\s+/).length
    if (wordCount >= 100) score += 10
    if (wordCount >= 300) score += 10
    
    // 包含图片加分
    if (content.images?.length > 0) score += 15
    
    // 格式规范加分
    if (this.hasGoodFormatting(content.text)) score += 10
    
    // 原创性检查
    const originalityScore = await this.checkOriginality(content.text)
    score += originalityScore * 0.15
    
    return Math.min(100, score)
  }
}

垃圾内容防护

// 反垃圾策略
class AntiSpamService {
  // 检测垃圾评论
  async detectSpam(content: string, context: SpamContext): Promise<SpamResult> {
    const signals: SpamSignal[] = []
    
    // 1. 链接检测
    const links = this.extractLinks(content)
    if (links.length > 2) {
      signals.push({ type: 'too_many_links', score: 30 })
    }
    
    // 检查可疑链接
    for (const link of links) {
      if (await this.isBlacklistedDomain(link)) {
        signals.push({ type: 'blacklisted_link', score: 80 })
      }
    }
    
    // 2. 重复内容检测
    const similarity = await this.checkSimilarContent(content, context.userId)
    if (similarity > 0.9) {
      signals.push({ type: 'duplicate_content', score: 60 })
    }
    
    // 3. 发布频率检测
    const recentPosts = await this.getRecentPostCount(context.userId, 60) // 60分钟内
    if (recentPosts > 10) {
      signals.push({ type: 'high_frequency', score: 40 })
    }
    
    // 4. 特征模式检测
    if (this.hasSpamPatterns(content)) {
      signals.push({ type: 'spam_patterns', score: 50 })
    }
    
    // 5. 新用户风险
    if (context.userAge < 24 * 60 * 60 * 1000) {  // 24小时内注册
      signals.push({ type: 'new_user', score: 20 })
    }
    
    // 计算综合得分
    const totalScore = signals.reduce((sum, s) => sum + s.score, 0)
    
    return {
      isSpam: totalScore >= 60,
      score: totalScore,
      signals
    }
  }
  
  // 垃圾内容模式检测
  private hasSpamPatterns(content: string): boolean {
    const patterns = [
      /(.)\1{5,}/,                    // 重复字符
      /[A-Z]{10,}/,                   // 全大写

      /(\d{5,})/g,                    // 长数字串
    ]
    
    return patterns.some(pattern => pattern.test(content))
  }
}

UGC SEO 技术优化

分页与索引策略

// UGC 分页 SEO 处理
function generatePaginationMeta(page: number, totalPages: number, baseUrl: string) {
  const meta: Record<string, string> = {}
  
  // 规范化 URL
  meta.canonical = page === 1 ? baseUrl : `${baseUrl}?page=${page}`
  
  // 分页链接
  if (page > 1) {
    meta.prev = page === 2 ? baseUrl : `${baseUrl}?page=${page - 1}`
  }
  if (page < totalPages) {
    meta.next = `${baseUrl}?page=${page + 1}`
  }
  
  // 超过一定页数不索引
  if (page > 50) {
    meta.robots = 'noindex, follow'
  }
  
  return meta
}

// 评论页面索引策略
function shouldIndexReviewPage(review: Review): boolean {
  // 高质量评论才索引
  if (review.content.length < 100) return false
  if (review.helpfulCount < 3) return false
  if (review.rating < 2 || review.rating > 4) return false  // 极端评价可能不客观
  
  return true
}
