上个月帮一个客户做 SEO 诊断,他说:"我们做了半年 SEO,每天发文章,但百度收录就几十篇,排名也上不去。"

我花了一小时检查他的网站,发现 28 项基础指标里,他只做到了 9 项。

我说:"你这地基都没打好,就想盖楼?"

后来帮他逐项整改,3 个月后收录破 500,核心词排到首页第二。

今天把这 28 项检查指标分享给你,不用花钱请专家,自己就能做诊断。

 

第一类:技术基础(8 项)

这是 SEO 的地基,地基不牢,后面白忙。

 1. 网站能被百度抓取

检查方法:百度搜索"site:你的域名",看有没有收录。

常见问题:

  • robots.txt 禁止了百度抓取
  • 服务器不稳定,百度蜘蛛来了几次都打不开,就不来了
  • 网站刚上线,还在审核期(一般 1-4 周)

合格标准:site 搜索有结果,且数量在增长。

 

 2. URL 结构清晰

好的 URL:xxx.com/product/seo-service.html

差的 URL:xxx.com/product.php?id=123&cat=456

检查要点:

  • URL 里有关键词(英文或拼音)
  • 层级不超过 3 级(首页→栏目→内容)
  • 不用动态参数(?&= 这些)
  • 全部小写,不用大写字母

 

 3. 301 重定向配置

带 www 和不带 www 的网址,应该跳转到同一个。

检查方法:分别访问 xxx.com 和 www.xxx.com,看是否跳转到同一个。

为什么重要:不跳转的话,百度会认为是两个网站,权重分散。

 

 4. 404 页面配置

检查方法:随便访问一个不存在的网址,看是否显示 404 页面。

404 页面应该有:

  • 友好提示("页面不存在")
  • 返回首页的链接
  • 热门推荐(引导用户继续浏览)

为什么重要:百度蜘蛛抓取到死链,会返回 404。如果没有 404 页面,会影响网站质量评分。

 

5. Sitemap 提交

Sitemap 是网站的"地图",告诉百度你有哪些页面。

检查方法:访问 xxx.com/sitemap.xml,看是否存在。

提交入口:百度站长平台(ziyuan.baidu.com)→ 网站支持 → 数据提交

注意:Sitemap 要定期更新,新增页面及时加入。

 

6. 网站加载速度

检查工具:Google PageSpeed Insights、百度统计速度诊断

合格标准:首屏加载时间 3 秒以内

优化方向:图片压缩、开启 CDN、代码压缩、服务器升级

速度慢,百度蜘蛛抓取效率低,用户体验也差。

 

 7. 移动端适配

检查方法:手机打开网站,看是否正常显示。

百度要求:2026 年起,移动端体验是排名因素之一。

适配方式:

  • 响应式设计(推荐):一套代码,自动适配
  • 移动站:m.xxx.com,单独做手机站
  • 自适应:PC 和移动同一 URL,样式不同

在百度站长平台提交移动适配规则。

 

 8. HTTPS 加密

检查方法:网址是 https:// 开头,浏览器显示小锁图标。

为什么重要:

  • 百度明确表示 HTTPS 是排名因素
  • 用户信任度更高
  • 防止数据被劫持

成本:有免费 SSL 证书(Let's Encrypt),也有付费的(几百到几千一年)。

 

第二类:页面优化(8 项)

页面是 SEO 的核心,每个页面都是一个"排名单元"。

 9. Title 标签优化

Title 是页面标题,是 SEO 最重要的因素之一。

检查方法:右键 → 查看源代码,找标签。</p> <p><strong>合格标准:</strong></p> <ul> <li>每个页面 title 唯一,不重复</li> <li>包含核心关键词</li> <li>长度 25-30 字(百度显示限制)</li> <li>格式:核心词 - 次要词 - 品牌名</li> </ul> <p><strong>错误案例:</strong>所有页面 title 都是"首页 - XXX 公司"</p> <p> </p> <h3> 10. Description 标签优化</h3> <p>Description 是页面描述,会显示在搜索结果里。</p> <p><strong>合格标准:</strong></p> <ul> <li>每个页面 description 唯一</li> <li>包含关键词(百度会加粗显示)</li> <li>长度 70-80 字</li> <li>有吸引力,引导用户点击</li> </ul> <p><strong>注意:</strong>Description 不直接影响排名,但影响点击率。</p> <p> </p> <h3> 11. H1/H2/H3 标签使用</h3> <p>标题标签告诉百度页面的内容结构。</p> <p><strong>正确用法:</strong></p> <ul> <li>H1:页面主标题,每页只能用 1 个</li> <li>H2:章节标题,可以用多个</li> <li>H3:子章节标题</li> </ul> <p><strong>检查方法:</strong>查看源代码,搜索<h1>、<h2>。</p> <p><strong>常见问题:</strong>一个页面多个 H1,或者根本没有 H1。</p> <p> </p> <h3> 12. 关键词布局</h3> <p><strong>关键词应该出现在:</strong></p> <ul> <li>Title 标签(最重要)</li> <li>Description 标签</li> <li>H1/H2 标题</li> <li>正文前 100 字</li> <li>图片 alt 属性</li> <li>URL 地址</li> <li>内链锚文本</li> </ul> <p><strong>注意:</strong>关键词密度 2-5% 即可,别堆砌。</p> <p> </p> <h3> 13. 图片 Alt 属性</h3> <p>百度不认识图片,要靠 alt 属性告诉它图片是什么。</p> <p><strong>检查方法:</strong>查看源代码,搜索<img>,看有没有 alt=""。</p> <p><strong>正确写法:</strong><img src="xxx.jpg" alt="北京网站建设服务"></p> <p><strong>错误写法:</strong><img src="xxx.jpg" alt="图片 1"> 或者没有 alt</p> <p> </p> <h3> 14. 内链结构</h3> <p>内链是网站内部页面之间的链接。</p> <p><strong>作用:</strong></p> <ul> <li>帮助百度蜘蛛抓取更多页面</li> <li>传递权重(首页→栏目页→内容页)</li> <li>提升用户体验</li> </ul> <p><strong>合格标准:</strong></p> <ul> <li>每个页面都有内链指向其他页面</li> <li>重要页面有更多内链指向</li> <li>导航清晰,用户 3 次点击内找到任何内容</li> </ul> <p> </p> <h3> 15. 面包屑导航</h3> <p>面包屑显示用户当前位置,比如:首页 > 产品服务 > 网站建设</p> <p><strong>作用:</strong></p> <ul> <li>帮助用户定位</li> <li>增强内链结构</li> <li>百度会在搜索结果里显示面包屑</li> </ul> <p><strong>检查:</strong>随便打开一个内页,看有没有面包屑导航。</p> <p> </p> <h3> 16. Canonical 标签</h3> <p>如果有多个 URL 显示相同内容,用 canonical 告诉百度哪个是"正版"。</p> <p><strong>使用场景:</strong></p> <ul> <li>同一内容多个 URL(比如带参数和不带参数)</li> <li>移动端和 PC 端内容相同</li> <li>转载内容(指向原文)</li> </ul> <p><strong>写法:</strong><link rel="canonical" href="https://xxx.com/original-page" /></p> <p> </p> <h2>第三类:内容建设(7 项)</h2> <p>内容是 SEO 的核心,百度最终是要给用户看内容的。</p> <h3> 17. 原创内容比例</h3> <p><strong>合格标准:</strong>原创内容 70% 以上</p> <p><strong>检查方法:</strong>随便抽几篇文章,复制到百度搜索,看有没有重复。</p> <p>百度优先收录和排名原创内容,抄袭的很难有排名。</p> <p> </p> <h3> 18. 内容更新频率</h3> <p><strong>建议频率:</strong></p> <ul> <li>新站:每天 1-2 篇(快速建立收录)</li> <li>老站:每周 2-3 篇(保持活跃)</li> </ul> <p><strong>关键:</strong>稳定比数量重要。每天 1 篇坚持一年,比一周 10 篇然后断更强。</p> <p> </p> <h3> 19. 内容质量</h3> <p><strong>优质内容标准:</strong></p> <ul> <li>字数 800 字以上(太短百度认为没价值)</li> <li>有实际信息,不是空话套话</li> <li>有图片、表格等丰富元素</li> <li>解决用户问题,不是纯广告</li> </ul> <p><strong>检查方法:</strong>自己读一遍,问自己:这篇文章对用户有用吗?</p> <p> </p> <h3> 20. 关键词覆盖</h3> <p><strong>检查:</strong>你的内容覆盖了哪些关键词?</p> <ul> <li>核心词(比如"网站建设")</li> <li>长尾词(比如"北京网站建设公司哪家好")</li> <li>问题词(比如"网站建设需要多少钱")</li> </ul> <p><strong>工具:</strong>5118、站长工具、百度指数,挖掘长尾词。</p> <p> </p> <h3> 21. 内容时效性</h3> <p>有些内容会过时,需要定期更新。</p> <p><strong>需要更新的内容:</strong></p> <ul> <li>带日期的("2024 年最新...")</li> <li>政策法规相关</li> <li>价格信息</li> <li>联系方式</li> </ul> <p><strong>建议:</strong>每季度检查一次老内容,更新过时信息。</p> <p> </p> <h3> 22. 专题/聚合页</h3> <p>把相关内容聚合到一起,形成专题页。</p> <p><strong>例子:</strong>"网站建设完全指南"专题,聚合所有建站相关文章。</p> <p><strong>作用:</strong></p> <ul> <li>提升用户体验(相关内容一站式看完)</li> <li>增强关键词权重(多个内容指向同一主题)</li> <li>容易获得排名(专题页权重高)</li> </ul> <p> </p> <h3> 23. 用户互动</h3> <p>评论、点赞、分享这些互动信号,百度会参考。</p> <p><strong>建议:</strong></p> <ul> <li>开启评论功能</li> <li>及时回复用户评论</li> <li>添加分享按钮</li> </ul> <p> </p> <h2>第四类:外链与数据(5 项)</h2> <p>外链是投票,数据是反馈。</p> <h3> 24. 外链数量增长</h3> <p><strong>检查工具:</strong>站长工具、爱站网、Ahrefs</p> <p><strong>合格标准:</strong>外链数量稳定增长,不是大起大落。</p> <p><strong>外链来源:</strong></p> <ul> <li>新闻媒体发稿</li> <li>行业网站投稿</li> <li>友情链接交换</li> <li>社交媒体分享</li> </ul> <p> </p> <h3> 25. 外链质量</h3> <p>1 个高质量外链,抵得上 100 个垃圾外链。</p> <p><strong>高质量外链特征:</strong></p> <ul> <li>来自高权重网站(百度权重 4+)</li> <li>来自相关行业网站</li> <li>来自内容页,不是垃圾目录页</li> <li>锚文本自然(不是"点击这里")</li> </ul> <p><strong>避免:</strong>买外链、群发外链、垃圾目录提交。</p> <p> </p> <h3> 26. 百度统计安装</h3> <p><strong>检查:</strong>网站是否安装百度统计代码。</p> <p><strong>作用:</strong></p> <ul> <li>追踪流量来源</li> <li>分析用户行为</li> <li>监控关键词排名带来的流量</li> </ul> <p>没有数据,SEO 就是盲人摸象。</p> <p> </p> <h3> 27. 百度站长平台绑定</h3> <p><strong>入口:</strong>ziyuan.baidu.com</p> <p><strong>功能:</strong></p> <ul> <li>提交 sitemap 和新增链接</li> <li>查看抓取诊断(百度蜘蛛能不能正常抓取)</li> <li>提交死链</li> <li>查看移动适配</li> <li>接收百度通知(违规提醒、算法更新)</li> </ul> <p>做百度 SEO,站长平台必须用。</p> <p> </p> <h3> 28. 关键词排名追踪</h3>

<p> </p> <h2>自查完了,然后呢?</h2> <p>对照上面 28 项,给自己打个分:</p> <ul> <li>25-28 项:优秀,继续保持</li> <li>20-24 项:良好,补齐短板</li> <li>15-19 项:及格,需要系统优化</li> <li>15 项以下:不及格,赶紧整改</li> </ul> <p> </p> <p><strong>整改建议:</strong></p> <ol> <li>先解决技术基础问题(第一类)——这是地基</li> <li>再优化页面要素(第二类)——这是框架</li> <li>然后持续做内容(第三类)——这是核心</li> <li>最后积累外链、监控数据(第四类)——这是助力</li> </ol> <p>SEO 不是一蹴而就的,一般 3-6 个月见效。坚持做对的事,时间会给你回报。</p> <p>不是所有项都必须满分,但基础项(技术基础 + 页面优化)必须做好。</p> <p>自查一遍,找出问题,逐项整改。3 个月后,你会回来感谢我的。</p> <p> </p> <p><em>(如果需要 SEO 诊断报告或代运营服务,可以加联系我们,免费给您做一次网站体检)</em></p> </div> </div> <!--/article
