 **验证**：33/33 测试通过
 
-## 八、规范说明
+## 八、GEO/SEO 升级（v20 · 2026-06-09）
+
+### 为 AI 搜索时代而生
+
+**背景**：ChatGPT、Perplexity、百度 AI 搜索等生成式引擎正在取代传统搜索。内容被 AI 引用的价值大于单纯的关键词排名。此版本让流水线生产的内容天然符合 AI 搜索偏好。
+
+### GEO 结构化数据
+
+每篇生成的 HTML 自动注入：
+
+- **JSON-LD Article schema** — `@context: schema.org`，含 headline/description/datePublished/author/publisher/keywords
+- **SEO meta tags** — `<meta name="description">`, `<meta name="keywords">`
+- **Open Graph tags** — `og:title`, `og:description`, `og:type`, `og:site_name`, `article:published_time`
+- **平台专用** — wechat/xiaohongshu 额外注入 `og:image`
+
+### 大纲 SEO 增强
+
+- outline prompt 新增 `seo_keywords` 变量（从研究笔记自动提取）
+- 每章要求至少融入 1 个 SEO 关键词
+- 新增 GEO 要求：每章包含可引用数据点，增加被 AI 搜索引用的概率
+
+### 搜索排名追踪
+
+| 模块 | 说明 |
+|------|------|
+| `SearchRanking` 模型 | 记录 article_id/keyword/position/url_found/ai_cited/search_engine |
+| `scripts/rank_tracker.py` | 对所有已发布文章，自动生成搜索查询 → 调用 Bing API 查排名 → 写入 DB |
+| 定时任务 | `scheduled_rank_tracker` 每日 07:00 自动运行 |
+| 管理后台 | admin.html 新增「搜索排名」tab，展示概览统计（累计检查/有排名/AI引用/最佳排名）+ 排名列表 |
+
+### 关键文件
+
+| 文件 | 改动 |
+|------|------|
+| `scripts/writer.py` | 新增 `inject_geo_metadata()`, `_extract_description()`, `_extract_tags_list()` — 在 `generate_platform_html()` 末尾注入 |
+| `scripts/outline.py` | 新增 `_extract_seo_keywords()` — 传入 outline prompt |
+| `scripts/prompt_loader.py` | outline_generation 提示词加入 `seo_keywords` 变量 + GEO 数据点要求 |
+| `scripts/rank_tracker.py` | 新建 — Bing 排名查询 + DB 写入 |
+| `platform/backend/app/models.py` | 新增 `SearchRanking` 模型 |
+| `platform/backend/app/api/search_rankings.py` | 新建 — `/api/seo/rankings` + `/api/seo/rankings/overview` |
+| `platform/backend/app/core/scheduler.py` | 新增 `scheduled_rank_tracker` 07:00 |
+| `platform/frontend/admin.html` | 新增「搜索排名」tab（统计卡片 + el-table 排名列表） |
