SEO Patterns
Core Principles
- Every public page MUST have a unique
<title>and<meta name="description">. - Structured data MUST validate against Google's Rich Results Test before shipping.
- Server-render all content critical for indexing.
- Canonical URLs are mandatory on every page.
Implementation Workflow
- Add meta tags and canonical URLs in server-rendered HTML.
- Checkpoint: every page has unique
<title>and<meta name="description">.
- Add structured data (JSON-LD) for the page type and keep blocks server-rendered.
- Checkpoint: Rich Results Test passes with zero errors.
- Generate / update sitemap and reference it from
robots.txt.
- Checkpoint: sitemap URL present in
robots.txtand accessible.
- Verify robots.txt rules and ensure public pages are allowed.
- Recovery: remove accidental
Disallow:entries and re-submit sitemap.
- Monitor Search Console for warnings and enhancement reports post-deploy.
Meta Tags & Open Graph
export const metadata: Metadata = {
title: 'Product Name — Short Descriptor',
description: 'Concise 150-160 char description with primary keyword.',
alternates: { canonical: 'https://example.com/page-slug' },
openGraph: {
title: 'Product Name — Short Descriptor',
description: 'Concise description for social sharing.',
url: 'https://example.com/page-slug',
type: 'website',
images: [{ url: 'https://example.com/og-image.jpg', width: 1200, height: 630 }],
},
twitter: { card: 'summary_large_image', title: 'Product Name — Short Descriptor', images: ['https://example.com/og-image.jpg'] },
robots: { index: true, follow: true },
};
Checklist: unique title (50-60 chars) · unique description (150-160 chars) · canonical URL · og:title/description/image (1200×630 px) · og:type · twitter:card/title/image · noindex only on admin/draft pages.
Structured Data & Crawlability
For structured data reference examples and detailed anti-patterns see REFERENCE.md.
- Generate XML sitemap dynamically from your data source (CMS, DB, filesystem).
- Use a sitemap index when >50,000 URLs or >50 MB.
- Include
<lastmod>only if accurate; submit via Google Search Console and reference inrobots.txt.
User-agent: *
Allow: /
Disallow: /admin/
Disallow: /api/
Disallow: /preview/
Sitemap: https://example.com/sitemap.xml
Crawlability checklist: robots.txt allows public pages · blocks admin/API/preview · XML sitemap auto-generated · referenced in robots.txt · no orphan pages · primary content in initial HTML · unique <h1> with keyword · structured data in SSR HTML · descriptive alt on images · no stray noindex · page load < 3s.
Anti-Patterns & Structured Data Reference
See REFERENCE.md for detailed structured data examples, validation commands, and a trimmed anti-pattern checklist.
