Google's Ranking Pipeline

谷歌排名流程

Content passes through sequential evaluation gates. Understanding this pipeline informs what to audit and why.
Mustang → Topicality (T*) → NavBoost → Twiddlers
   ↓           ↓              ↓           ↓
 Initial   Query-match    User clicks   Final
 scoring   relevance      (13 months)   adjustments
Key Implications:
  • Content must pass Mustang's quality gate before relevance even matters
  • User behavior (NavBoost) accumulates over 13 months—patience required
  • Two foundational pillars: Q* (site quality) and P* (popularity via Chrome data)
  • Page potential is capped by domain's
    siteAuthority
    score
See
assets/google-ranking-signals.yaml
for complete signal reference.
内容会通过一系列评估关卡。理解这一流程有助于明确审计的内容和原因。
Mustang → Topicality (T*) → NavBoost → Twiddlers
   ↓           ↓              ↓           ↓
 初始评分   查询匹配相关性   用户点击(13个月)   最终调整
核心启示:
  • 内容必须先通过Mustang的质量关卡,相关性才会被纳入考量
  • 用户行为(NavBoost)数据需要13个月的积累——需保持耐心
  • 两大基础支柱:Q*(网站质量)和P*(基于Chrome数据的受欢迎度)
  • 页面潜力受域名

Audit Framework

审计框架

Phase 0: Domain & History Context

阶段0:域名与历史背景

Before auditing content, assess domain-level factors that cap page potential:
Domain Authority Check:
  • Established domain (>6 months) or new domain sandbox?
  • Site-wide quality signals (clutterScore, ad density)
  • Homepage authority inheritance for new pages
  • Brand entity recognition (
    queriesForWhichOfficial
    )
URL History Assessment:
  • Is this an established URL with history?
  • URL changes reset accumulated trust (Google tracks last 20 versions)
  • Evergreen URL structure (no dates unless news content)
  • URL permanence strategy in place
Sandbox Awareness (New Domains/Pages):
FactorStatusImpact
hostAgeNew (<6mo) / EstablishedDomain-level sandbox
documentHistoryNew URL / Has historyPage-level demotion
Graduation signalsSocial, backlinks, engagementExit sandbox
If new domain: Set realistic expectations. Dual sandbox (host + document) requires consistent quality publishing, backlinks, and positive engagement over months.
在审计内容前,先评估会限制页面潜力的域名层面因素:
域名权威度检查:
  • 已建立域名(超过6个月)还是新域名沙盒期?
  • 全站质量信号(clutterScore、广告密度)
  • 新页面的首页权威度继承情况
  • 品牌实体识别度(
    queriesForWhichOfficial
URL历史评估:
  • 该URL是否为有历史积累的成熟URL?
  • URL变更会重置积累的信任度(谷歌会追踪最近20个版本)
  • 采用常青URL结构(除非是新闻内容,否则避免包含日期)
  • 已制定URL永久化策略
沙盒意识(新域名/页面):
因素状态影响
hostAge新域名(<6个月)/ 已建立域名层面沙盒限制
documentHistory新URL / 有历史积累页面层面降权
毕业信号社交互动、反向链接、用户参与度脱离沙盒期
如果是新域名: 设定现实预期。双重沙盒(主机+文档)要求持续发布高质量内容、积累反向链接和正向用户互动,耗时数月才能脱离。

Phase 1: Technical SEO Check

阶段1:技术SEO检查

Evaluate foundational technical elements:
Page-Level Technical:
  • URL structure (clean, descriptive, <60 chars, evergreen)
  • Title tag (50-60 chars, keyword in first 30) → affects
    titlematchScore
  • Meta description (150-160 chars, compelling CTA)
  • H1 tag (single, matches topic)
  • Header hierarchy (logical H1→H2→H3) → larger text weighted higher
  • Image alt text (descriptive, keyword-relevant)
  • Internal links (contextual, relevant)
  • External links (authoritative sources)
Site-Level Technical:
  • HTTPS enabled
  • Mobile-friendly
  • Page speed (<1.8s mobile)
  • Schema markup present
  • XML sitemap inclusion
  • robots.txt accessibility
Entity & Trust Signals:
  • Verifiable ownership/authorship (disconnected entity problem)
  • Contact information accessible
  • Organization schema linking to Knowledge Graph
评估基础技术要素:
页面层面技术检查:
  • URL结构(简洁、描述性、<60字符、常青型)
  • 标题标签(50-60字符,关键词置于前30字符内)→ 影响
    titlematchScore
  • 元描述(150-160字符,包含吸引人的行动号召)
  • H1标签(唯一,与主题匹配)
  • 标题层级(逻辑化H1→H2→H3)→ 字号越大权重越高
  • 图片替代文本(描述性、与关键词相关)
  • 内部链接(上下文相关)
  • 外部链接(权威来源)
站点层面技术检查:
  • 已启用HTTPS
  • 移动端友好
  • 页面加载速度(移动端<1.8秒)
  • 存在Schema标记
  • 已纳入XML站点地图
  • robots.txt可访问
实体与信任信号:
  • 可验证的所有权/作者身份(解决实体脱节问题)
  • 联系信息可获取
  • 组织Schema标记关联至知识图谱

Phase 2: Content Quality Assessment

阶段2:内容质量评估

Evaluate content depth and value. Google's
contentEffort
signal measures ML-assessed effort invested.
Content Completeness:
FactorCheckScoreSignal
Topic coverageComprehensive vs. shallow/10contentEffort
Unique valueOriginal insights vs. rehash/10OriginalContentScore
AccuracyFactual, verifiable/10Trust signals
FreshnessCurrent data/sources/10semanticDate
DepthExpert-level detail/10contentEffort
Token Truncation Awareness: Google uses token limits—long documents may be truncated. Optimize for this:
  • Critical information in first 20% of content (inverted pyramid)
  • Key facts lead each section
  • Paragraphs <120 words
  • Front-load value, don't bury it
Readability:
  • Reading level (target: Grade 8-10)
  • Paragraph length (2-3 sentences ideal)
  • Sentence variety
  • Scannable formatting (bullets, headers)
  • Visual aids (images, tables, diagrams)
Freshness Audit: Google evaluates freshness through three distinct methods:
  • Explicit byline date (visible, accurate)
  • URL date signals (avoid dates in evergreen URLs)
  • Semantic freshness (are facts/sources current, not just timestamp?)
⚠️ Freshness spam detection: Changing timestamps without updating substance is detected via
semanticDate
comparison.
评估内容深度与价值。谷歌的
contentEffort
信号用于衡量AI评估的内容投入程度。
内容完整性:
因素检查项得分信号
主题覆盖全面 vs 浅显/10contentEffort
独特价值原创见解 vs 重复内容/10OriginalContentScore
准确性事实可验证/10信任信号
新鲜度数据/来源时效性/10semanticDate
深度专家级细节/10contentEffort
令牌截断注意事项: 谷歌采用令牌限制——长文档可能会被截断。针对此优化:
  • 关键信息置于内容前20%(倒金字塔结构)
  • 每个章节以核心事实开头
  • 段落长度<120词
  • 前置核心价值,避免隐藏
可读性:
  • 阅读难度(目标:8-10年级水平)
  • 段落长度(2-3句为最佳)
  • 句式多样性
  • 便于扫描的格式(项目符号、标题)
  • 视觉辅助(图片、表格、图表)
新鲜度审计: 谷歌通过三种不同方式评估新鲜度:
  • 明确的署名日期(可见、准确)
  • URL日期信号(常青URL避免包含日期)
  • 语义新鲜度(事实/来源是否时效性强,而非仅看时间戳?)
⚠️ 新鲜度垃圾检测: 通过
semanticDate
对比,可检测出仅修改时间戳而未更新内容实质的行为。

Phase 3: Keyword & Semantic Analysis

阶段3:关键词与语义分析

Assess keyword optimization. Affects Topicality (T*) stage scoring.
Primary Keyword:
  • Present in title tag (first 30 chars ideal)
  • In H1 and early H2s

Semantic Coverage:
  • LSI keywords present
  • Related entities covered (
    webrefEntities
    signal)
  • Topic cluster alignment
  • Question variations addressed
  • Search intent match
Entity Optimization:
  • Content associates with Knowledge Graph entities
  • Clear entity relationships established
  • Supports topical authority building
评估关键词优化情况,影响Topicality(T*)阶段的评分。
核心关键词:
  • 出现在标题标签中(理想位置为前30字符)
  • 出现在H1和早期H2标签中
  • 自然密度(0.5-1.5%)
  • 出现在元描述中
  • 出现在前100词内
语义覆盖:
  • 包含LSI关键词
  • 覆盖相关实体(
    webrefEntities
    信号)
  • 与主题集群对齐
  • 覆盖问题变体
  • 匹配搜索意图
实体优化:

  • Contact information (disconnected entity fix)
  • Privacy policy
  • Editorial guidelines
  • Reviews/testimonials

Disconnected Entity Check: Sites without verifiable ownership, author info, and contact transparency trigger algorithmic distrust—even with high content quality.
评估经验、专业度、权威度、信任信号,这些直接对应技术信号。
经验信号:
  • 标明第一手经验
  • 包含案例研究/示例
  • 原创数据/研究
  • 流程文档

  • 已发表研究
信任信号:
  • 联系信息(解决实体脱节问题)
  • 隐私政策
  • 编辑准则
  • 评价/推荐
  • 安全标识
实体脱节检查: 无验证所有权、作者信息和联系透明度的网站,即使内容质量高,也会触发算法不信任。

Phase 5: AI/GEO Readiness

阶段5:AI/GEO就绪性

Assess content for LLM visibility:
Extractability:
  • TL;DR or summary present (first 100 words)
  • Paragraphs <120 words (token limit friendly)
