+## 🚀 IndexNow Implementation (Bing Instant Indexing)
+
+### What is IndexNow?
+IndexNow is an API that allows instant notification to search engines when content changes, instead of waiting for crawlers.
+
+**Supported by:** Bing, Yandex, Seznam.cz, Naver
+
+### Setup Instructions
+
+1. **Generate API Key**
+   ```bash
+   # Generate a random UUID or hex string (32+ characters)
+   npm install uuid
+   node -e "console.log(require('uuid').v4())"
+   ```
+
+2. **Create Key File**
+   - Create a file named `{your-key}.txt` in `/public/`
+   - Example: `a1b2c3d4-e5f6-7890-abcd-ef1234567890.txt`
+   - Put your key inside the file (just the key text)
+   - Make it accessible at: `https://davian.space/{your-key}.txt`
+
+3. **Use the IndexNow Utility**
+   ```javascript
+   import submitToIndexNow from './utils/indexNow';
+
+   const API_KEY = 'a1b2c3d4-e5f6-7890-abcd-ef1234567890';
+   const HOST = 'davian.space';
+
+   // Submit when content changes
+   await submitToIndexNow(
+     'https://davian.space/',
+     HOST,
+     API_KEY
+   );
+   ```
+
+### When to Submit
+- ✅ New content published
+- ✅ Content updated significantly
+- ✅ Content deleted (submit with 404 or 410 status)
+- ❌ Don't spam - only submit real changes
+
+---
