+# SEO Improvements for WebDrop
+
+This document outlines the comprehensive SEO improvements implemented to make WebDrop more discoverable on search engines like Google.
+
+## Overview
+
+The following SEO enhancements have been implemented to improve WebDrop's visibility and ranking on search engines:
+
+## 1. Metadata Enhancements
+
+### Root Layout (`app/layout.tsx`)
+- **Title Template**: Dynamic page titles with "| WebDrop" suffix
+- **Enhanced Description**: Detailed description with key features (500MB file transfer, end-to-end encryption, WebRTC)
+- **Keywords**: Comprehensive list of relevant keywords for file transfer, P2P, WebRTC, and secure file sharing
+- **Open Graph Tags**: Complete social media sharing metadata for Facebook, LinkedIn, etc.
+- **Twitter Card**: Twitter-specific metadata for better link previews
+- **Canonical URLs**: Prevent duplicate content issues
+- **Robots Meta**: Properly configured for search engine crawling
+- **Icons**: Favicon, app icons, and Apple touch icons
+
+### Page-Specific Metadata
+Each major page now has its own metadata:
+- **Login Page**: `/auth/login/layout.tsx`
+- **Sign Up Page**: `/auth/sign-up/layout.tsx`
+- **Room Page**: `/room/layout.tsx`
+- **Profile Page**: `/profile/layout.tsx` (noindex for privacy)
+- **404 Page**: `/app/not-found.tsx` (noindex, custom design)
+
+## 2. Structured Data (JSON-LD)
+
+Added schema.org structured data to the landing page (`app/page.tsx`):
+
+### WebSite Schema
+- Site name, URL, and description
+- SearchAction for search engines to understand the site structure
+
+### WebApplication Schema
+- Application category: Utility
+- Operating system: Any (browser-based)
+- Pricing: Free ($0)
+- Feature list highlighting key capabilities
+- Browser requirements
+
+### Organization Schema
+- Organization name and URL
+- Logo reference
+- Social media links (GitHub)
+
+## 3. Sitemap
+
+**File**: `app/sitemap.ts`
+
+Dynamically generated XML sitemap including:
+- Homepage (priority: 1.0, monthly updates)
+- Auth pages (priority: 0.8, monthly updates)
+- Room page (priority: 0.9, weekly updates)
+
+The sitemap is automatically available at `/sitemap.xml`
+
+## 4. Robots.txt
+
+**File**: `public/robots.txt`
+
+Configuration:
+- Allows all search engine crawlers
+- Blocks `/auth/` and `/api/` routes from indexing
+- References sitemap location
+
+## 5. Web App Manifest
+
+**File**: `app/manifest.ts`
+
+PWA-ready manifest including:
+- App name and short name
+- Description
+- Theme colors
+- Display mode: standalone
+- App icons (192x192, 512x512)
+
+Automatically available at `/manifest.webmanifest`
+
+## 6. Icons and Images
+
+### Favicon and App Icons
+- **Primary Icon**: `/app/icon.svg` - Automatically used by Next.js
+- **192x192 Icon**: `/public/icon-192.svg` (with PNG symlink)
+- **512x512 Icon**: `/public/icon-512.svg` (with PNG symlink)
+- **Apple Touch Icon**: `/public/apple-icon.svg`
+
+### Open Graph Image
+- **File**: `/public/og-image.svg` (with PNG symlink)
+- **Dimensions**: 1200x630px (optimal for social media)
+- **Usage**: Displayed when sharing links on social media
+
+## 7. Search Engine Verification
+
+Placeholder verification codes are included in `app/layout.tsx`:
+- **Google Search Console**: `google-site-verification-code`
+- **Yandex Webmaster**: `yandex-verification-code`
+
+### How to Add Verification Codes:
+
+1. **Google Search Console**:
+   - Visit [Google Search Console](https://search.google.com/search-console)
+   - Add your property (https://webdrop.vercel.app)
+   - Choose "HTML tag" verification method
+   - Copy the verification code from the meta tag
+   - Replace `google-site-verification-code` in `app/layout.tsx`
+
+2. **Yandex Webmaster**:
+   - Visit [Yandex Webmaster](https://webmaster.yandex.com/)
+   - Add your site
+   - Choose meta tag verification
+   - Replace `yandex-verification-code` in `app/layout.tsx`
+
+## 8. Technical SEO Best Practices
+
+### Implemented:

+- ✅ Meta description optimization
+- ✅ Mobile-responsive design (already present)
