Technical SEO

技术SEO

The infrastructure layer of SEO. Technical SEO ensures search engines can discover, crawl, render, and index your pages. It is the foundation - if crawling fails, content quality and link building are irrelevant. This skill covers the crawl-index-rank pipeline and the engineering decisions that make or break search visibility.
SEO的基础设施层。技术SEO确保搜索引擎能够发现、抓取、渲染并索引你的页面。它是基础——如果抓取失败，内容质量和外链建设都将毫无意义。此技能涵盖了抓取-索引-排名的流程，以及那些决定搜索可见性成败的工程决策。

Key principles

核心原则

  1. Crawlable before rankable - A page that Googlebot cannot reach cannot rank. Discovery is step one in the pipeline. Fix crawl and index issues before any other SEO work. Crawlability is a precondition, not a ranking factor.
  2. One canonical URL per piece of content - Every distinct piece of content must have exactly one URL that all signals consolidate on. HTTP vs HTTPS, www vs non-www, trailing slash vs none, query parameters - each variant dilutes ranking signals unless canonicalized to a single source of truth.
  3. Rendering strategy is an SEO architecture decision - Whether your page is rendered at build time (SSG), at request time on the server (SSR), or in the browser (CSR) determines whether Googlebot sees your content on the first crawl or must wait for a second-wave JavaScript render. Make this decision deliberately.
  4. robots.txt blocks crawling, not indexing - A page blocked in 
    robots.txt
    can still be indexed if other pages link to it. Googlebot sees the URL via links but cannot read the content, so it may index a thin or empty page. Use 
    noindex
    in the HTTP response header or meta tag to prevent indexing, not 
    robots.txt
    .
  5. Redirect chains waste crawl budget and dilute link equity - Each hop in a redirect chain costs crawl budget and reduces the link equity passed through. Keep all redirects as single-hop 301s from old URL directly to final destination.
  1. 可抓取才有可能排名 - Googlebot无法访问的页面无法获得排名。发现是流程的第一步。在进行任何其他SEO工作之前，先修复抓取和索引问题。可抓取性是前提条件，而非排名因素。
  2. 每个内容对应一个规范URL - 每个独特的内容必须有且仅有一个URL作为所有信号的聚合点。HTTP与HTTPS、www与非www、带斜杠与不带斜杠、查询参数——除非将这些变体规范到单一的权威URL，否则每个变体都会稀释排名信号。
  3. 渲染策略是SEO架构决策 - 你的页面是在构建时渲染（SSG）、请求时在服务器渲染（SSR）还是在浏览器渲染（CSR），决定了Googlebot在首次抓取时能否看到你的内容，还是必须等待第二波JavaScript渲染。请慎重做出此决策。
  4. robots.txt阻止抓取而非索引 - 如果其他页面链接到被
    robots.txt
    阻止的页面，该页面仍可能被索引。Googlebot通过链接发现该URL，但无法读取内容，因此可能会索引一个空或内容单薄的页面。要阻止索引，请在HTTP响应头或meta标签中使用
    noindex
    ，而非
    robots.txt
    。
  5. 重定向链浪费抓取预算并稀释链接权益 - 重定向链中的每一跳都会消耗抓取预算，并减少传递的链接权益。将所有重定向设置为从旧URL直接指向最终目标的单跳301重定向。

Core concepts

核心概念

The crawl-index-rank pipeline

抓取-索引-排名流程

Three sequential phases - failure in any phase stops everything downstream:
PhaseWhat happensCommon failure modes
CrawlGooglebot discovers and fetches the URLrobots.txt block, slow server, crawl budget exhausted
IndexGoogle processes and stores the pagenoindex directive, duplicate content, thin content, render failure
RankGoogle assigns position for queriesContent quality, E-E-A-T, links, page experience
三个连续阶段——任何一个阶段失败都会导致后续流程停滞：
阶段操作内容常见失败模式
抓取Googlebot发现并获取URLrobots.txt阻止、服务器缓慢、抓取预算耗尽
索引Google处理并存储页面noindex指令、重复内容、内容单薄、渲染失败
排名Google为查询分配位置内容质量、E-E-A-T、外链、页面体验

Crawl budget

抓取预算

Crawl budget is the number of URLs Googlebot will crawl on your site within a given timeframe. It is a product of crawl rate (how fast Googlebot can crawl without overloading the server) and crawl demand (how much Google wants to crawl based on page value and freshness).
Who needs to care about crawl budget:
  • Sites with 10k+ pages
  • Sites with large faceted navigation generating URL permutations
  • Sites with many low-value or duplicate URLs (pagination, filters, sessions in URLs)
  • Sites with frequent content updates that need fast re-indexing
Small sites (<1k pages) with clean architecture rarely face crawl budget problems.
抓取预算是指Googlebot在特定时间范围内会抓取你的站点的URL数量。它是抓取速率（Googlebot在不使服务器过载的情况下的抓取速度）和抓取需求（Google根据页面价值和新鲜度想要抓取的程度）的产物。
需要关注抓取预算的站点：
  • 拥有10k+页面的站点
  • 拥有大量分面导航生成URL排列的站点
  • 拥有许多低价值或重复URL（分页、筛选器、URL中的会话ID）的站点
  • 内容频繁更新且需要快速重新索引的站点
架构简洁的小型站点（<1k页面）很少遇到抓取预算问题。

Rendering for crawlers

针对爬虫的渲染

Googlebot can execute JavaScript but does so in a second wave, sometimes days after the initial crawl. Content invisible without JavaScript is at risk:
RenderingGooglebot sees on first crawlSEO risk
SSG (static)Full HTMLNone
SSR (server-side)Full HTMLNone
ISR (incremental static)Full HTML (on cache hit)Minor - stale cache shows old content
CSR (client-side only)Empty shellHigh - content may not be indexed
Googlebot可以执行JavaScript，但会在第二波进行，有时在首次抓取几天后才会执行。不借助JavaScript就不可见的内容存在风险：
渲染方式Googlebot首次抓取时看到的内容SEO风险
SSG（静态）完整HTML无
SSR（服务器端）完整HTML无
ISR（增量静态）完整HTML（缓存命中时）轻微 - 过期缓存会显示旧内容
CSR（仅客户端）空壳页面高 - 内容可能无法被索引

URL parameter handling

URL参数处理

URL parameters are a major source of duplicate content. Common problematic patterns:
  • Tracking parameters: 
    ?utm_source=email&utm_campaign=launch
  • Faceted navigation: 
    ?color=red&size=M&sort=price
  • Session IDs: 
    ?sessionid=abc123
  • Pagination: 
    ?page=2
Handle with: canonical tags pointing to the clean URL, robots.txt 
Disallow
for pure tracking parameters, or Google Search Console parameter handling.
URL参数是重复内容的主要来源。常见的问题模式：
  • 跟踪参数：
    ?utm_source=email&utm_campaign=launch
  • 分面导航：
    ?color=red&size=M&sort=price
  • 会话ID：
    ?sessionid=abc123
  • 分页：
    ?page=2
处理方式：使用指向干净URL的规范标签、在robots.txt中
Disallow
纯跟踪参数，或通过Google Search Console处理参数。

Mobile-first indexing

移动优先索引

Google indexes and ranks primarily based on the mobile version of your content. Ensure the mobile version has: the same content as desktop, the same structured data, and equivalent meta tags. Blocked mobile CSS/JS is a common cause of mobile-first indexing failures.
Google主要根据内容的移动版本进行索引和排名。确保移动版本拥有与桌面版本相同的内容、相同的结构化数据和等效的meta标签。被阻止的移动CSS/JS是移动优先索引失败的常见原因。

Common tasks

常见任务

Configure robots.txt

配置robots.txt

undefined
undefined

Allow all crawlers to access all content (default, no file needed)

允许所有爬虫访问所有内容（默认，无需文件）

User-agent: * Allow: /
User-agent: * Allow: /

Block specific directories from all crawlers

阻止所有爬虫访问特定目录

User-agent: * Disallow: /admin/ Disallow: /internal-search/ Disallow: /checkout/ Disallow: /?*sessionid= # block session ID URLs
User-agent: * Disallow: /admin/ Disallow: /internal-search/ Disallow: /checkout/ Disallow: /?*sessionid= # 阻止带会话ID的URL

Allow Googlebot to crawl CSS and JS (critical - never block these)

允许Googlebot抓取CSS和JS（至关重要——切勿阻止）

User-agent: Googlebot Allow: /.js$ Allow: /.css$
User-agent: Googlebot Allow: /.js$ Allow: /.css$

Point to sitemap

指定站点地图位置

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

> Never disallow CSS or JS. Googlebot needs them to render your pages. Blocking
> them degrades rendering quality and can hurt rankings.
Sitemap: https://example.com/sitemap.xml

> 切勿阻止CSS或JS。Googlebot需要它们来渲染页面。阻止它们会降低渲染质量，可能损害排名。

Generate an XML sitemap

生成XML站点地图

xml
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc>https://example.com/</loc>
    <lastmod>2024-01-15</lastmod>
    <changefreq>weekly</changefreq>
    <priority>1.0</priority>
  </url>
  <url>
    <loc>https://example.com/products/widget</loc>
    <lastmod>2024-01-10</lastmod>
    <changefreq>monthly</changefreq>
    <priority>0.8</priority>
  </url>
</urlset>
For large sites, use a sitemap index:
xml
<?xml version="1.0" encoding="UTF-8"?>
<sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <sitemap>
    <loc>https://example.com/sitemaps/products.xml</loc>
    <lastmod>2024-01-15</lastmod>
  </sitemap>
  <sitemap>
    <loc>https://example.com/sitemaps/blog.xml</loc>
    <lastmod>2024-01-15</lastmod>
  </sitemap>
</sitemapindex>
Sitemap rules: max 50,000 URLs per file, max 50MB uncompressed. Only include canonical, indexable URLs. Only include 
lastmod
if it reflects genuine content changes - Googlebot learns to ignore dishonest lastmod values.
xml
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc>https://example.com/</loc>
    <lastmod>2024-01-15</lastmod>
    <changefreq>weekly</changefreq>
    <priority>1.0</priority>
  </url>
  <url>
    <loc>https://example.com/products/widget</loc>
    <lastmod>2024-01-10</lastmod>
    <changefreq>monthly</changefreq>
    <priority>0.8</priority>
  </url>
</urlset>
对于大型站点，使用站点地图索引：
xml
<?xml version="1.0" encoding="UTF-8"?>
<sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <sitemap>
    <loc>https://example.com/sitemaps/products.xml</loc>
    <lastmod>2024-01-15</lastmod>
  </sitemap>
  <sitemap>
    <loc>https://example.com/sitemaps/blog.xml</loc>
    <lastmod>2024-01-15</lastmod>
  </sitemap>
</sitemapindex>
站点地图规则：每个文件最多包含50,000个URL，未压缩时最大50MB。仅包含规范的、可索引的URL。仅当
lastmod
反映真实的内容变化时才添加——Googlebot会学会忽略不真实的lastmod值。

Set up canonical URLs

设置规范URL

In the 
<head>
element:
html
<link rel="canonical" href="https://example.com/products/widget" />
Handle all URL variants consistently:
html
<!-- All of these should resolve to one canonical form -->
<!-- https://example.com/products/widget/ -->
<!-- https://example.com/products/widget  -->
<!-- http://example.com/products/widget   -->
<!-- https://www.example.com/products/widget -->

<!-- All pages declare the same canonical -->
<link rel="canonical" href="https://example.com/products/widget" />
For paginated pages, each page is canonically itself (do not canonical page 2 to page 1 unless they have identical content):
html
<!-- Page 1 -->
<link rel="canonical" href="https://example.com/blog" />

<!-- Page 2 -->
<link rel="canonical" href="https://example.com/blog?page=2" />
在
<head>
元素中：
html
<link rel="canonical" href="https://example.com/products/widget" />
一致地处理所有URL变体：
html
<!-- 所有这些URL都应解析为同一个规范形式 -->
<!-- https://example.com/products/widget/ -->
<!-- https://example.com/products/widget  -->
<!-- http://example.com/products/widget   -->
<!-- https://www.example.com/products/widget -->

<!-- 所有页面都声明同一个规范URL -->
<link rel="canonical" href="https://example.com/products/widget" />
对于分页页面，每个页面的规范URL指向自身（除非内容完全相同，否则不要将第2页规范到第1页）：
html
<!-- 第1页 -->
<link rel="canonical" href="https://example.com/blog" />

<!-- 第2页 -->
<link rel="canonical" href="https://example.com/blog?page=2" />

Choose a rendering strategy

选择渲染策略

Decision table for ranking pages (pages you want to appear in search):
Content typeRecommended strategyRationale
Marketing pages, landing pagesSSGCrawled immediately, fast TTFB
Blog posts, documentationSSGRarely changes, build on publish
Product pages (10k-100k)ISRManageable builds, auto-updates
User profiles, social contentSSRPersonalized but crawlable
Search results, filtersSSR + canonicalCrawlable canonical version
Dashboards, account pagesCSR is fineBehind auth, not indexed anyway
For Next.js:
typescript
// SSG - crawled immediately, best for ranking pages
export async function generateStaticParams() { ... }

// ISR - rebuilds on demand, good for large catalogs
export const revalidate = 3600; // revalidate every hour

// SSR - server renders on every request
export const dynamic = 'force-dynamic';
排名页面（你希望出现在搜索结果中的页面）的决策表：
内容类型推荐策略理由
营销页面、落地页SSG立即被抓取，TTFB快
博客文章、文档SSG很少更改，发布时构建
产品页面（10k-100k）ISR构建量可控，自动更新
用户资料、社交内容SSR个性化但可抓取
搜索结果、筛选器SSR + 规范URL可抓取的规范版本
仪表板、账户页面CSR即可在权限验证后方，不会被索引
对于Next.js：
typescript
// SSG - 立即被抓取，最适合排名页面
export async function generateStaticParams() { ... }

// ISR - 按需重建，适合大型目录
export const revalidate = 3600; // 每小时重新验证一次

// SSR - 每次请求都在服务器渲染
export const dynamic = 'force-dynamic';

Fix redirect chains

修复重定向链

Redirect chains occur when A -> B -> C instead of A -> C directly. Detect and fix:
bash
undefined
当出现A -> B -> C而非A -> C的情况时，就会形成重定向链。检测并修复：
bash
undefined

Detect redirect chain depth with curl

使用curl检测重定向链深度

curl -L -o /dev/null -s -w "%{url_effective} hops: %{num_redirects}\n"
https://example.com/old-page
curl -L -o /dev/null -s -w "%{url_effective} hops: %{num_redirects}\n"
https://example.com/old-page

Follow the chain step by step

逐步跟踪重定向链

curl -I https://example.com/old-page
curl -I https://example.com/old-page

Note Location header, then:

记录Location头，然后执行：

curl -I https://example.com/intermediate-page

Fix by updating the origin redirect to point directly to the final URL:

```nginx
curl -I https://example.com/intermediate-page

通过更新源重定向直接指向最终URL来修复：

```nginx

Before: /old-page -> /intermediate -> /final-page (chain)

之前：/old-page -> /intermediate -> /final-page（链式）

After: /old-page -> /final-page (single hop)

之后：/old-page -> /final-page（单跳）

rewrite ^/old-page$ /final-page permanent;

Rules:
- 301 = permanent redirect (passes link equity, cached by browsers)
- 302 = temporary redirect (does not pass full link equity, not cached)
- Use 301 for SEO unless the redirect is genuinely temporary
- Client-side redirects (`window.location`, meta refresh) do not reliably pass
  link equity. Always redirect at the server or CDN layer.
rewrite ^/old-page$ /final-page permanent;

规则：
- 301 = 永久重定向（传递链接权益，被浏览器缓存）
- 302 = 临时重定向（不传递全部链接权益，不被缓存）
- 除非重定向确实是临时的，否则SEO场景下使用301
- 客户端重定向（`window.location`、meta refresh）无法可靠传递链接权益。始终在服务器或CDN层进行重定向。

Handle URL parameters for faceted navigation

处理分面导航的URL参数

Faceted navigation generates an exponential number of URL combinations. Choose one:
Option A: Canonical to the base category page (simplest)
html
<!-- /products?color=red&size=M&sort=price -->
<link rel="canonical" href="https://example.com/products" />
Option B: robots.txt disallow parameter combinations
User-agent: *
Disallow: /*?*color=
Disallow: /*?*size=
Disallow: /*?*sort=
Option C: Noindex on parameterized pages
html
<meta name="robots" content="noindex, follow" />
Option A is preferred when the canonical page has good content. Option B is useful when you want to conserve crawl budget. Option C is the fallback when you need to serve the page to users but not have it indexed.
分面导航会生成指数级数量的URL组合。选择以下方式之一：
选项A：规范到基础分类页面（最简单）
html
<!-- /products?color=red&size=M&sort=price -->
<link rel="canonical" href="https://example.com/products" />
选项B：在robots.txt中阻止参数组合
User-agent: *
Disallow: /*?*color=
Disallow: /*?*size=
Disallow: /*?*sort=
选项C：对带参数的页面设置noindex
html
<meta name="robots" content="noindex, follow" />
当规范页面内容优质时，优先选择选项A。当你想要节省抓取预算时，选项B很有用。当你需要为用户提供页面但不希望其被索引时，选项C是备选方案。

Set up meta robots directives

设置meta robots指令

In the HTML 
<head>
:
html
<!-- Default: crawl and index (no tag needed) -->
<meta name="robots" content="index, follow" />

<!-- Do not index, but follow links on this page -->
<meta name="robots" content="noindex, follow" />

<!-- Do not index, do not follow links -->
<meta name="robots" content="noindex, nofollow" />

<!-- Prevent Google from showing a cached version -->
<meta name="robots" content="index, follow, noarchive" />
Via HTTP response header (works for non-HTML resources like PDFs):
X-Robots-Tag: noindex
X-Robots-Tag: noindex, nofollow
在HTML 
<head>
中：
html
<!-- 默认：抓取并索引（无需标签） -->
<meta name="robots" content="index, follow" />

<!-- 不索引，但跟踪页面上的链接 -->
<meta name="robots" content="noindex, follow" />

<!-- 不索引，不跟踪链接 -->
<meta name="robots" content="noindex, nofollow" />

<!-- 阻止Google显示缓存版本 -->
<meta name="robots" content="index, follow, noarchive" />
通过HTTP响应头设置（适用于PDF等非HTML资源）：
X-Robots-Tag: noindex
X-Robots-Tag: noindex, nofollow

Debug indexing issues

调试索引问题

When a page is not indexed, work through this checklist in order:
  1. URL Inspection tool in Search Console - checks crawl status, last crawl, indexing decision, and renders a screenshot of what Googlebot sees
  2. robots.txt tester - confirm the URL is not blocked
  3. Live URL test - request indexing and see if Googlebot can render the page
  4. Check for noindex - view source and search for 
    noindex
    , check HTTP headers
  5. Check canonical - is the canonical pointing to a different URL?
  6. Check content - is there enough unique, substantive content?
  7. Check internal links - is the page linked from anywhere Googlebot can reach?
当页面未被索引时，按以下清单依次排查：
  1. Search Console中的URL检查工具 - 检查抓取状态、上次抓取时间、索引决策，并渲染Googlebot看到的页面截图
  2. robots.txt测试工具 - 确认URL未被阻止
  3. 实时URL测试 - 请求索引并查看Googlebot能否渲染页面
  4. 检查noindex - 查看源代码并搜索
    noindex
    ，检查HTTP头
  5. 检查规范URL - 规范URL是否指向其他URL？
  6. 检查内容 - 是否有足够的独特、实质性内容？
  7. 检查内部链接 - 该页面是否被Googlebot可访问的任何页面链接？
