## 🏗️ Architecture & Deployment
109+
110+
This project uses a **Multi-Entry SPA** architecture to ensure perfect compatibility with GitHub Pages, Google AdSense, and SEO crawlers.
111+
112+
### The Problem it Solves
113+
GitHub Pages is a static host. By default, visiting a deep link like `/Free-Tools/word-counter` returns a **404 Not Found** because that physical file doesn't exist. This breaks AdSense (which requires HTTP 200 OK) and hurts SEO.
114+
115+
### The Solution: Multi-Entry SPA
116+
During the build process (`npm run build`), we programmatically generate physical directories and `index.html` files for every route:
117+
118+
```text
119+
dist/
120+
├── index.html (Root entry point)
121+
├── .nojekyll (Prevents Jekyll processing)
122+
├── 404.html (Smart fallback for typos)
123+
├── word-counter/
124+
│ └── index.html (Copy of main index.html)
125+
└── ...
126+
```
127+
128+
When a user requests `/Free-Tools/word-counter`, GitHub Pages serves the physical file at `dist/word-counter/index.html` with **HTTP 200 OK**.
129+
130+
### 🛠️ Automated Workflow
131+
132+
We have automated the entire process to prevent errors:
133+
134+
1. **`npm run validate-routes`**: Checks that every route defined in `src/App.jsx` matches the routes in `generate-sitemap.js`. Runs automatically before build.
135+
2. **`node generate-sitemap.js`**:
136+
* Generates `sitemap.xml`.
137+
* Creates the physical folder structure in `dist/`.
138+
* Creates `.nojekyll` and `404.html`.
139+
3. **Use `npm run prepare-deploy`**: Runs the full sequence: Validate → Build → Generate.
140+
141+
### ➕ Adding a New Tool
142+
143+
1. Add the route in `src/App.jsx`.
144+
2. Add the route to the `routes` array in `generate-sitemap.js`.
145+
3. Run `npm run validate-routes` to verify.
146+

## 📜 Implementation Summary (Dec 2025)
150+
151+
**Objective**: Fix 404 errors on GitHub Pages for AdSense & SEO.
152+
153+
**Key Changes:**
154+
* **Physical Route Generation**: `generate-sitemap.js` now creates real folders for every route.
155+
* **Smart Fallback**: `public/404.html` handles typos gracefully; `public/.nojekyll` bypasses Jekyll.
156+
* **Safety**: `scripts/validate-routes.js` ensures `App.jsx` and `sitemap` are always in sync.
157+
* **Result**: **Zero 404s**, full AdSense compatibility, and perfect SEO tags.
