+# SEO 优化说明
+
+本项目已完成基础 SEO 优化，以下是已实施的改动。
+
+## 已完成的优化项
+
+### 1. HTML Meta 标签优化 ✅
+
+在 `index.html` 中添加了完整的 SEO 元数据：
+
+- **基础 Meta 标签**
+  - title, description, keywords
+  - author, theme-color
+  - canonical URL
+  
+- **Open Graph 标签**（社交媒体分享优化）
+  - og:type, og:url, og:title
+  - og:description, og:image, og:site_name
+  
+- **Twitter Card 标签**
+  - twitter:card, twitter:title
+  - twitter:description, twitter:image
+
+- **结构化数据**（JSON-LD）
+  - Schema.org WebSite 类型标记
+  - 提升搜索引擎理解能力
+
+### 2. SEO 配置文件 ✅
+
+- **`public/robots.txt`** - 搜索引擎爬虫规则
+  - 允许所有爬虫访问
+  - 指定 sitemap 位置
+  
+- **`public/sitemap.xml`** - 站点地图（自动生成）
+  - 包含所有工具页面 URL
+  - 设置更新频率和优先级
+  - 通过 `scripts/generate-sitemap.ts` 自动生成
+  
+- **`public/manifest.json`** - PWA 配置
+  - 支持渐进式 Web 应用
+  - 改善移动端体验
+
+### 3. 构建流程优化 ✅
+
+- **`package.json`**
+  - 构建时自动生成 sitemap
+  - 添加 tsx 依赖用于运行生成脚本
+
+## 文件清单
+
+### 新增文件
+```
+public/
+├── robots.txt              # 爬虫规则
+├── sitemap.xml            # 站点地图（自动生成）
+└── manifest.json          # PWA 配置
+
+scripts/
+└── generate-sitemap.ts    # Sitemap 生成脚本
+```
+
+### 修改文件
+```
+index.html                 # 添加 SEO meta 标签和结构化数据
+package.json               # 添加 sitemap 生成命令
+```
+
+## 使用说明
+
+### 开发
+```bash
+pnpm install               # 安装依赖
+pnpm dev                   # 启动开发服务器
+```
+
+### 构建
+```bash
+pnpm run build             # 构建项目（自动生成 sitemap）
+pnpm run generate:sitemap  # 单独生成 sitemap
+```
+
+### 部署前检查
+
+⚠️ **重要：部署前必须更新配置文件中的域名！**
+
+需要将以下文件中的 `https://litek.typist.cc` 替换为你的实际域名：
+
+1. **`index.html`**
+   - canonical URL
+   - Open Graph URL 和 image
+   - Twitter Card image
+   - Structured Data URL
+
+2. **`public/robots.txt`**
+   - Sitemap URL
+
+3. **`scripts/generate-sitemap.ts`**
+   - BASE_URL 常量
+
+更新后重新构建：
+```bash
+pnpm run build
+```
+
+## SEO 验证
+
+### 部署后验证
+
+1. **提交 sitemap 到 Google Search Console**
+   - 访问 https://search.google.com/search-console
+   - 添加网站资源
+   - 提交 sitemap: `https://你的域名/sitemap.xml`
+
+2. **测试结构化数据**
+   - 访问 https://validator.schema.org/
+   - 输入网站 URL
+   - 检查是否有错误
+
+3. **测试 Open Graph 预览**
+   - Facebook: https://developers.facebook.com/tools/debug/
+   - Twitter: https://cards-dev.twitter.com/validator
+
+4. **性能测试**
+   - Google PageSpeed Insights: https://pagespeed.web.dev/
+   - 目标分数: SEO > 95
+
+## 可访问的 URL
+
+部署后，以下 URL 应该可以正常访问：
+
+- `https://你的域名/` - 主页
+- `https://你的域名/robots.txt` - 爬虫规则
+- `https://你的域名/sitemap.xml` - 站点地图
+- `https://你的域名/manifest.json` - PWA 配置
+- `https://你的域名/tool/uuid` - UUID 工具
+- `https://你的域名/tool/json` - JSON 工具
+- `https://你的域名/tool/base64` - Base64 工具
+- `https://你的域名/tool/network/dns` - DNS 工具
+- ... 其他工具页面
+
+## 添加新工具时更新 SEO
+
+当添加新工具时，需要更新 `scripts/generate-sitemap.ts`：
+
+```typescript
+const tools = [
+  // 现有工具...
+  { path: '/tool/你的新工具', priority: '0.9' },
+];
+```
+
+然后重新构建项目。
+
+## SEO 效果预期
+
+- **1-2 周**：搜索引擎开始索引页面
+- **1-2 月**：主要关键词开始有排名
+- **3-6 月**：稳定的搜索排名和自然流量增长
+
+## 技术栈
+
+- React 19 + TypeScript
+- Vite (Rolldown)
+- React Router v7
+- Radix UI + Tailwind CSS 4
+- Nginx
