4. 抓取和索引管理

4. Crawling and Indexing Management

** robots.txt 最佳实践:**
User-agent: *
Allow: /
Disallow: /admin/
Disallow: /private/
Disallow: /checkout/
Disallow: /cart/

Sitemap: https://example.com/sitemap.xml

Crawl-delay: 1
** XML Sitemap 配置:**
xml
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc>https://example.com/page/</loc>
    <lastmod>2024-01-15</lastmod>
    <changefreq>weekly</changefreq>
    <priority>0.8</priority>
  </url>
</urlset>
规范链接 (Canonical URL):
html
<!-- 防止重复内容问题 -->
<link rel="canonical" href="https://example.com/canonical-page/" />

<!-- 处理参数和跟踪码 -->
<link rel="canonical" href="https://example.com/product/?utm_source=google" />
robots.txt best practices:
User-agent: *
Allow: /
Disallow: /admin/
Disallow: /private/
Disallow: /checkout/
Disallow: /cart/

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc>https://example.com/page/</loc>
    <lastmod>2024-01-15</lastmod>
    <changefreq>weekly</changefreq>
    <priority>0.8</priority>
  </url>
</urlset>
Canonical URL:
html
<!-- 防止重复内容问题 -->
<link rel="canonical" href="https://example.com/canonical-page/" />

<!-- 处理参数和跟踪码 -->

6. 常见技术问题诊断

6. Common Technical Problem Diagnosis

问题:页面未被索引
诊断步骤:
1. 检查 robots.txt 是否阻止抓取
2. 检查页面 canonical 是否指向其他URL
3. 使用 URL Inspection Tool 检查索引状态
4. 检查页面是否返回正确 HTTP 状态码
5. 审查页面内容和质量
问题:抓取预算浪费
优化建议:
1. 清理低价值页面(空页面、薄内容)
2. 设置参数处理规则(Google Search Console)
3. 优化内部链接结构
4. 使用 noindex 控制非必要页面索引
5. 提交 XML Sitemap 帮助蜘蛛发现新内容
问题:重复内容
解决方案:
1. 统一 URL 格式(带/不带 www)
2. 设置 canonical 标签
3. 处理 URL 参数问题
4. 使用 301 重定向合并相似页面
