Initial Assessment
初步评估
Check for product marketing context first: If or exists, read it for target keywords and content type.
.claude/product-marketing-context.md.cursor/product-marketing-context.mdIdentify:
- Content type: Article, guide, listicle, pillar, news
- Target keyword: Primary and secondary
- Competitors: Top 10 average length and structure — see competitor-research
优先检查产品营销上下文：如果存在或文件，先读取获取目标关键词和内容类型要求。
.claude/product-marketing-context.md.cursor/product-marketing-context.md确认以下信息：
- 内容类型：文章、指南、清单文、支柱内容、新闻
- 目标关键词：主关键词和次要关键词
- 竞争对手：搜索结果前10名的平均内容长度和结构，可参考competitor-research能力
Word Count
字数规范
Google does not rank by word count. Length should match search intent and topic depth. A 1,000-word post that satisfies intent can outrank a 3,000-word thin piece.
谷歌不会单纯根据字数排名，内容长度需要匹配搜索意图和主题深度。一篇满足用户意图的1000字文章，排名可以高于内容单薄的3000字文章。
Reference Ranges by Content Type
不同内容类型的参考字数范围
| Content type | Word count | Notes |
|---|---|---|
| News / announcements | 300–600 | Time-sensitive; concise |
| Standard articles / how-tos | 1,000–1,500 | Single topic; actionable |
| Listicles / guides | 1,200–2,000 | "Top 10," "Best X" |
| Pillar / cornerstone | 2,000–3,500+ | Comprehensive; cluster hub |
| Competitive keywords | 2,000–2,500 | Top 10 avg ~2,400 words |
| 内容类型 | 字数范围 | 说明 |
|---|---|---|
| 新闻/公告 | 300–600 | 时效性强，要求简洁 |
| 标准文章/操作指南 | 1,000–1,500 | 聚焦单个主题，可落地性强 |
| 清单文/指南 | 1,200–2,000 | 例如“Top 10”、“最佳XX”类内容 |
| 支柱/基石内容 | 2,000–3,500+ | 内容全面，作为内容集群的中心 |
| 高竞争关键词内容 | 2,000–2,500 | 搜索前10名平均长度约2400字 |
Strategy
字数策略
- Analyze top 10 for target keyword — average length and depth
- Match intent — informational often needs ~40% longer than transactional
- Value over padding — each section must add genuine value; avoid fluff
- Comprehensive coverage — answer the query and related questions
- 分析目标关键词搜索结果前10名的平均长度和内容深度
- 匹配搜索意图：信息类内容通常比交易类内容长40%左右
- 价值优先于凑字数：每个章节都需要提供真实价值，避免无意义的填充内容
- 覆盖全面：回答核心查询以及相关衍生问题
H2 Heading Keywords
H2标题关键词规范
Placement
放置位置
- Primary keyword: Include naturally in at least one H2 when relevant
- Related keywords: Use LSI and long-tail in other H2s for topical coverage
- Avoid stuffing: Headings must stay clear and readable; organic placement only
- 主关键词：相关度高的情况下，至少在1个H2中自然提及
- 相关关键词：其他H2中使用LSI关键词和长尾关键词，覆盖主题相关内容
- 避免堆砌：标题需要清晰易读，仅自然放置关键词
Quantity
数量规范
- No strict limit — one H2 per major section; structure follows content
- Typical article: 4–8 H2s; pillar: 8–15+ H2s
- Hierarchy: H1 → H2 (major sections) → H3 (subsections); don't skip levels
- 无严格限制：每个主要章节对应一个H2，结构跟随内容逻辑设置
- 常规文章：4–8个H2；支柱内容：8–15+个H2
- 层级逻辑：H1 → H2（主要章节） → H3（子章节），不要跳过层级
Best Practices
最佳实践
| Practice | Purpose |
|---|---|
| Descriptive H2s | Search engines understand context; users scan |
| Answer-first | Place direct answer in first 40–50 words after H2 for Featured Snippets; see featured-snippet |
| Keyword variation | Use related terms; avoid repeating exact phrase in every H2 |
| Logical flow | H2s outline the article; support topical authority |
| 实践方法 | 作用 |
|---|---|
| 描述性H2 | 便于搜索引擎理解内容上下文，也方便用户快速扫读 |
| 答案前置 | 在H2后的前40-50字内给出直接答案，便于获取Featured Snippets，参考featured-snippet能力 |
| 关键词变体：使用相关术语，避免每个H2都重复完全相同的关键词短语 | |
| 逻辑流畅：H2构成文章的大纲，有助于提升主题权威性 |
Keyword Density vs Keyword Stuffing
关键词密度与关键词堆砌
Definitions
定义
| Term | Meaning |
|---|---|
| Keyword density | (Keyword count / Total words) × 100; a metric, not a ranking factor |
| Keyword stuffing | Excessive, unnatural repetition to manipulate rankings; black-hat |
| 术语 | 含义 |
|---|---|
| 关键词密度 | (关键词出现次数 / 总字数) × 100；仅作为参考指标，不是排名因子 |
| 关键词堆砌：过度、不自然地重复关键词以操纵排名，属于黑帽SEO行为 |
Current Guidance
当前官方指导
- Keyword density is not a direct ranking factor — Google has stated since 2011 that repetition alone doesn't improve rankings
- Reference range: 0.5%–1.5% for most content; some sources cite up to 2.5%
- Use density mainly to avoid stuffing — if density exceeds ~2–3% and reads unnaturally, reduce
- Prioritize natural placement: title, H1, first 100 words, 1–2 H2s, body; avoid forced repetition
- 关键词密度不是直接排名因子：谷歌从2011年就明确表示，单纯重复关键词不会提升排名
- 参考范围：大部分内容的关键词密度在0.5%–1.5%即可，部分来源认为最高不超过2.5%
- 密度主要用于避免堆砌：如果密度超过2%-3%且读起来不自然，就需要减少关键词出现次数
- 优先自然放置：标题、H1、前100字、1-2个H2、正文中自然提及即可，避免强行重复
How to Avoid Stuffing
避免堆砌的方法
- Write for users first; keywords should fit naturally
- Use synonyms, related terms, and question phrasing
- If a sentence sounds awkward with the keyword, rewrite
- Monitor: if every paragraph repeats the exact phrase, simplify
- 优先为用户写作，关键词要自然融入内容
- 使用同义词、相关术语和问句表述
- 如果加关键词后句子读起来很生硬，就重写句子
- 自查：如果每个段落都重复完全相同的关键词短语，就简化表述
Multimedia: Images, Tables, Lists
多媒体优化：图片、表格、列表
Images
图片
| Practice | Purpose |
|---|---|
| Alt text | Descriptive; include keyword when natural; accessibility |
| File names | Descriptive (e.g. |
| Compression | WebP; optimize for LCP |
| Captions | Relevant to topic; can support Featured Snippets; see featured-snippet |
| Original over stock | Unique images signal E-E-A-T — see eeat-signals |
Full image optimization (alt, format, responsive, lazy loading, image sitemap, LCP): see image-optimization.
| 实践方法 | 作用 |
|---|---|
| Alt文本：描述性内容，自然包含关键词，兼顾无障碍访问 | |
文件名：使用描述性文件名，例如 | |
| 压缩：使用WebP格式，优化LCP指标 | |
| 图注：和主题相关，可助力获取Featured Snippets，参考featured-snippet能力 | |
| 原创优先于图库图：独特图片是E-E-A-T的信号，参考eeat-signals能力 |
完整的图片优化（Alt文本、格式、响应式、懒加载、图片站点地图、LCP）可参考image-optimization能力。
Tables
表格
- Use for: Comparisons, stats, specs, "X vs Y"
- Semantic HTML: ,
<table>,<thead>, clear column headers<tbody> - Featured Snippets: ~6% of snippets are tables; optimize headers with target keywords. See featured-snippet
- Mobile: Responsive; avoid horizontal scroll when possible
- Data quality: No empty cells; consistent units; accurate, current data
- 适用场景：对比、数据统计、参数、“XX vs XX”类内容
- 语义化HTML：使用、
<table>、<thead>标签，设置清晰的列标题<tbody> - Featured Snippets：约6%的片段为表格形式，使用目标关键词优化标题，参考featured-snippet能力
- 移动端适配：响应式设计，尽量避免横向滚动
- 数据质量：无空白单元格，单位统一，数据准确及时
Lists: Ordered vs Unordered
列表：有序vs无序列表
| Type | Use case | SEO / Snippet |
|---|---|---|
Ordered ( | Steps, rankings, sequences, "Top 10" | List snippets (~19% of Featured Snippets); how-to; see featured-snippet |
Unordered ( | Non-sequential items, features, options | Bullet snippets; definitions, options |
Best practices:
- Use semantic and
<ol>; avoid divs styled as lists<ul> - Answer-first: For snippet targets, put the direct answer in the first 40–50 words after the heading
- Concise items: List items should be scannable; expand in body if needed
- Logical order: Ordered lists = sequence matters; unordered = no sequence
| 类型 | 适用场景 | SEO/片段价值 |
|---|---|---|
有序列表 ( | 步骤、排名、序列、“Top 10”类内容 | 列表片段（约占Featured Snippets的19%）；操作指南类内容，参考featured-snippet能力 |
无序列表 ( | 非序列类条目、功能、选项 | 项目符号片段；适合定义、选项类内容 |
最佳实践：
- 使用语义化和
<ol>标签，避免用div模拟列表样式<ul> - 答案前置：如果目标是获取片段，在标题后的前40-50字内给出直接答案
- 条目简洁：列表条目要便于扫读，需要展开的内容放在正文中
- 逻辑顺序：有序列表表示顺序重要，无序列表没有顺序要求
GEO / AI Citation
GEO/AI引用优化
Answer-first (direct answer in first 40–60 words after H2) supports both Featured Snippets and GEO. For article-level GEO (TL;DR, Key Takeaways, QAE pattern), see article-page-generator and generative-engine-optimization. For Featured Snippet formats and optimization, see featured-snippet.
答案前置（H2后的前40-60字给出直接答案）同时有助于获取Featured Snippets和GEO展示。文章层面的GEO优化（摘要、核心要点、QAE模式）可参考article-page-generator和generative-engine-optimization能力。Featured Snippet格式和优化方法参考featured-snippet能力。
