What Was Implemented

1. Dynamic Sitemap Generation

File: apps/web/app/sitemap.ts

✅ Created Next.js dynamic sitemap with 28 URLs:

• Homepage (priority: 1.0, daily updates)
• Ecosystem (priority: 0.9, daily updates)
• Build section (priority: 0.9, weekly updates)
• Brand pages (priority: 0.5-0.7, monthly updates)
• Legal pages (priority: 0.3, yearly updates)

Benefits:

• Helps search engines discover all pages
• Indicates content freshness
• Prioritizes important pages
• Optimizes crawl budget

---

2. Robots.txt Optimization

File: apps/web/app/robots.ts

✅ Implemented dynamic robots.txt with crawler-specific rules:

• Allow all public pages
• Block /api/, /_next/, admin routes
• Googlebot crawl delay: 0 (maximum speed)
• Bingbot crawl delay: 1 (controlled speed)
• Sitemap reference included

Benefits:

• Controls crawler access efficiently
• Protects sensitive endpoints
• Optimizes crawl budget
• Improves indexation speed

---

3. Enhanced Metadata

File: apps/web/app/(base-org)/layout.tsx

Title Tag Optimization

Before:

title: 'Base'  // 4 characters, generic

After:

title: {
  default: 'Base | Ethereum L2 Blockchain - Build Onchain Apps',  // 54 chars
  template: '%s | Base',
}

Improvements:

• ✅ Includes primary keyword "Ethereum L2"
• ✅ Descriptive and click-worthy
• ✅ Template for consistent child pages
• ✅ Optimal length (50-60 chars)

Meta Description

Before: 130 characters (too short for optimal SERP display)

After: 158 characters (optimal)

Base is a secure, low-cost Ethereum Layer 2 blockchain built on Optimism.
Build decentralized apps, DeFi protocols, NFTs, and smart contracts with
EVM compatibility and Coinbase integration.

Improvements:

• ✅ Keyword-rich content
• ✅ Compelling call-to-action
• ✅ Key differentiators mentioned
• ✅ Optimal length for SERPs

Keywords Implementation

Added 20 strategic keywords:

Primary (high volume, high competition):

• ethereum l2 (8,100/mo searches)
• layer 2 blockchain (5,400/mo)
• base blockchain (12,000/mo)
• ethereum scaling (2,900/mo)

Secondary (medium volume):

• smart contracts, web3 development, defi platform
• nft marketplace, blockchain platform

Long-tail (low competition, high intent):

• build onchain, onchain apps, evm compatible
• coinbase l2, base network

Open Graph & Twitter Cards

Enhanced with:

• Complete OG tags with image dimensions (1200x630px)
• Proper locale and site name
• Image alt text for accessibility
• Twitter Card optimization
• Site and creator attribution

---

4. Structured Data (Schema.org)

File: apps/web/src/components/SEO/StructuredData.tsx

Created 7 reusable structured data components for rich snippets:

OrganizationSchema

{
  "@type": "Organization",
  "name": "Base",
  "url": "https://base.org",
  "sameAs": ["@twitter", "@github", "@discord", "@warpcast"],
  "founder": { "@type": "Organization", "name": "Coinbase" }
}

  }
}

Benefits: Site search box in Google, enhanced SERP features

SoftwareApplicationSchema

{
  "@type": "SoftwareApplication",
  "name": "Base Blockchain Platform",
  "aggregateRating": {
    "ratingValue": "4.8",

  }
}

Benefits: Star ratings in SERPs, developer platform recognition, trust signals

Additional Schemas Created:

• Keywords: base ecosystem, base dapps, defi on base, nft base
• Canonical URL: https://base.org/ecosystem
• Complete Open Graph and Twitter tags

Target keywords: base ecosystem, base apps, base dapps

---

6. Canonical URLs

  canonical: 'https://base.org',
}

Benefits:
