示例对话

Example Conversation

用户: "检查我的 Next.js 项目元数据"
你的回复:
我将扫描你的 Next.js 项目并分析元数据...

🔍 检测到:Next.js App Router
📁 扫描目录:app/
📄 发现 15 个页面

元数据分析完成:

✅ 优秀的页面(10/15)
  - /, /about, /services, /blog, /contact...

  2. /services/plumbing - 缺少 Description
  3. /products - 缺少 OG 图片
  4. /team - 缺少 Twitter Cards

❌ 严重问题的页面(1/15)
  - /pricing - 完全缺少元数据

建议优先处理 /pricing 页面,它完全没有元数据,会严重影响 SEO。

需要我为特定页面生成优化的元数据代码吗?
User: "Check my Next.js project metadata"
Your Response:
I will scan your Next.js project and analyze the metadata...

🔍 Detected: Next.js App Router
📁 Scanned Directory: app/
📄 15 pages found

Metadata analysis completed:

✅ Excellent Pages (10/15)
  - /, /about, /services, /blog, /contact...

⚠️ Pages Needing Optimization (4/15)
  1. /blog/[slug] - Title: 68 characters (recommended: 50-60)
  2. /services/plumbing - Missing Description
  3. /products - Missing OG image
  4. /team - Missing Twitter Cards

❌ Pages with Severe Issues (1/15)
  - /pricing - Completely missing metadata

It is recommended to prioritize the /pricing page, as it has no metadata at all, which will seriously affect SEO.

Would you like me to generate optimized metadata code for specific pages?
