Site Architecture Skill

Load with: base.md + web-content.md

For technical website structure that enables discovery by search engines AND AI crawlers (GPTBot, ClaudeBot, PerplexityBot).

Philosophy

Content is king. Architecture is the kingdom.

Great content buried in poor architecture won't be discovered. This skill covers the technical foundation that makes your content findable by:

• Google, Bing (traditional search)
• GPTBot (ChatGPT), ClaudeBot, PerplexityBot (AI assistants)
• Social platforms (Open Graph, Twitter Cards)

Next.js Metadata

// app/layout.tsx
import { Metadata } from 'next';

export const metadata: Metadata = {
  metadataBase: new URL('https://yoursite.com'),
  title: {
    default: 'Brand Name',
    template: '%s | Brand Name',
  },
  description: 'Your default site description.',
  keywords: ['keyword1', 'keyword2', 'keyword3'],
  authors: [{ name: 'Brand Name', url: 'https://yoursite.com' }],
  creator: 'Brand Name',
  publisher: 'Brand Name',
  robots: {
    index: true,
    follow: true,

      index: true,
      follow: true,

    images: [
      {
        url: '/og-image.jpg',
        width: 1200,

  const post = await getPost(params.slug);

  return {
    title: post.title,
    description: post.excerpt,
    openGraph: {
      title: post.title,
      description: post.excerpt,
      type: 'article',
      publishedTime: post.publishedAt,
      modifiedTime: post.updatedAt,
      authors: [post.author.name],
      images: [post.coverImage],
    },
  };
}

URL Structure

Best Practices

✅ GOOD URLs:
/blog/ai-seo-best-practices
/products/pro-plan
/pricing
/about/team

❌ BAD URLs:
/blog?id=123
/p/12345
/index.php?page=about
/Products/Pro_Plan (inconsistent casing)

URL Guidelines

Redirect Configuration

// next.config.js
module.exports = {
  async redirects() {
    return [
      // Redirect old URLs to new
      {
        source: '/old-page',
        destination: '/new-page',
        permanent: true, // 301 redirect
      },
      // Redirect with wildcard
      {
        source: '/blog/old/:slug',
        destination: '/articles/:slug',
        permanent: true,
      },
      // Trailing slash redirect
      {
        source: '/:path+/',
        destination: '/:path+',
        permanent: true,
      },
    ];
  },
};

Canonical URLs

Implementation

<!-- Always include canonical, even for primary URL -->
<link rel="canonical" href="https://yoursite.com/current-page">

When to Use

✅ USE CANONICAL:
- Every page (even if only version exists)
- Paginated content (point to page 1 or use rel=prev/next)
- URL parameters that don't change content (?utm_source=...)
- HTTP vs HTTPS (canonical to HTTPS)
- www vs non-www (pick one, canonical to it)

Example: /products?sort=price should canonical to /products

Next.js Canonical

// Automatic in metadata
export const metadata: Metadata = {
  alternates: {
    canonical: '/current-page',
  },
};

Security Headers

Essential Headers

// next.config.js
const securityHeaders = [
  {
    key: 'X-DNS-Prefetch-Control',
    value: 'on',
  },
  {
    key: 'Strict-Transport-Security',
    value: 'max-age=63072000; includeSubDomains; preload',
  },
  {
    key: 'X-Frame-Options',
    value: 'SAMEORIGIN',
  },
  {
    key: 'X-Content-Type-Options',
    value: 'nosniff',
  },
  {
    key: 'Referrer-Policy',
    value: 'strict-origin-when-cross-origin',
  },
  {
    key: 'Permissions-Policy',
    value: 'camera=(), microphone=(), geolocation=()',
  },
];

module.exports = {
  async headers() {
    return [
      {
        source: '/:path*',
        headers: securityHeaders,
      },
    ];
  },
};

Core Web Vitals

Target Metrics

Optimization Checklist

## LCP (Loading)
- [ ] Optimize largest image (WebP, proper sizing)
- [ ] Preload critical assets
- [ ] Use CDN for static assets
- [ ] Enable compression (gzip/brotli)
- [ ] Minimize render-blocking resources

## INP (Interactivity)
- [ ] Minimize JavaScript execution time
- [ ] Break up long tasks
- [ ] Use web workers for heavy computation
- [ ] Optimize event handlers
- [ ] Lazy load non-critical JS

## CLS (Visual Stability)
- [ ] Set dimensions on images/videos
- [ ] Reserve space for dynamic content
- [ ] Avoid inserting content above existing
- [ ] Use transform for animations
- [ ] Preload fonts

Next.js Performance

// Image optimization
import Image from 'next/image';

<Image
  src="/hero.jpg"
  alt="Hero image"
  width={1200}
  height={630}
  priority // Preload for LCP
  placeholder="blur"
  blurDataURL={blurDataUrl}
/>

// Font optimization
import { Inter } from 'next/font/google';

const inter = Inter({
  subsets: ['latin'],
  display: 'swap', // Prevent FOIT
});

// Dynamic imports
import dynamic from 'next/dynamic';

const HeavyComponent = dynamic(() => import('./HeavyComponent'), {
  loading: () => <Skeleton />,
  ssr: false, // Client-only if needed
});

Internal Linking

Structure

## Link Architecture

Homepage
├── /pricing (1 click)
├── /features (1 click)
├── /blog (1 click)
│   ├── /blog/category-1 (2 clicks)
│   │   └── /blog/category-1/post (3 clicks)
│   └── /blog/category-2 (2 clicks)
└── /about (1 click)

Rule: Every page within 3 clicks of homepage

Best Practices

✅ DO:
- Use descriptive anchor text
- Link contextually within content
- Create hub pages for topics
- Link to related content at end of posts
- Use breadcrumbs for navigation

❌ AVOID:
- "Click here" as anchor text
- Orphan pages (no internal links)
- Too many links per page (>100)
- Broken internal links
- Redirect chains

Breadcrumbs

// components/Breadcrumbs.tsx
import Link from 'next/link';

interface BreadcrumbItem {
  name: string;
  href: string;
}

export function Breadcrumbs({ items }: { items: BreadcrumbItem[] }) {
  const jsonLd = {
    '@context': 'https://schema.org',
    '@type': 'BreadcrumbList',
    itemListElement: items.map((item, index) => ({
      '@type': 'ListItem',
      position: index + 1,
      name: item.name,
      item: `https://yoursite.com${item.href}`,
    })),
  };

  return (
    <>
      <script
        type="application/ld+json"
        dangerouslySetInnerHTML={{ __html: JSON.stringify(jsonLd) }}
      />
      <nav aria-label="Breadcrumb">
        <ol className="flex gap-2">
          {items.map((item, index) => (
            <li key={item.href}>
              {index > 0 && <span>/</span>}
              <Link href={item.href}>{item.name}</Link>
            </li>
          ))}
        </ol>
      </nav>
    </>
  );
}

AI Crawler Handling

Known AI Crawlers

Allow AI Discovery, Block Training (Optional)

# robots.txt

# Allow GPTBot for ChatGPT browsing
User-agent: GPTBot
Allow: /

# Block CCBot (used for training datasets)
User-agent: CCBot
Disallow: /

# Block Google AI training, allow search
User-agent: Google-Extended
Disallow: /

AI-Specific Meta Tags

<!-- Block AI training but allow indexing -->
<meta name="robots" content="index, follow, max-image-preview:large">

<!-- Opt out of AI training (proposed standard) -->
<meta name="ai-training" content="disallow">

Structured Data Placement

Where to Add Schema

<!-- Option 1: In <head> with JSON-LD (recommended) -->
<head>
  <script type="application/ld+json">
    {
      "@context": "https://schema.org",
      "@type": "Organization",
      "name": "Your Company"
    }
  </script>
</head>

<!-- Option 2: Before closing </body> -->
<body>
  <!-- Page content -->
  <script type="application/ld+json">
    { "@context": "https://schema.org", ... }
  </script>
</body>

Multiple Schema Per Page

<head>
  <!-- Organization (site-wide) -->
  <script type="application/ld+json">
    { "@context": "https://schema.org", "@type": "Organization", ... }
  </script>

  <!-- BreadcrumbList (navigation) -->
  <script type="application/ld+json">
    { "@context": "https://schema.org", "@type": "BreadcrumbList", ... }
  </script>

  <!-- Article (page-specific) -->
  <script type="application/ld+json">
    { "@context": "https://schema.org", "@type": "Article", ... }
  </script>

  <!-- FAQPage (if FAQ section exists) -->
  <script type="application/ld+json">
    { "@context": "https://schema.org", "@type": "FAQPage", ... }
  </script>
</head>
