## What it does

The skill instructs the agent to enforce technical search engine optimization standards across modern web frameworks. It requires semantic HTML tags like `main` or `article`, heading hierarchies from `h1` to `h6`, descriptive kebab-case URLs, and meaningful link text. Image rules mandate explicit width and height values to prevent layout shifts, WebP formatting, and descriptive alt attributes.

Performance guidelines focus on Core Web Vitals metrics including LCP, CLS, and FID. The instructions favor React Server Components. They minimize `'use client'` and client state hooks. Non-critical components require dynamic imports and `Suspense` wrappers with fallbacks.

For metadata handling, the rules target framework-native tools. Next.js setups use the `metadata` export or `generateMetadata` alongside Open Graph and canonical tags. Nuxt.js apps rely on `useHead` and `useSeoMeta` composables. Because the guide prioritizes server rendering and Server Components, purely client-rendered single-page applications will clash with its architectural rules.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill seo-best-practices -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/seo-best-practices/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/seo-best-practices/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill seo-best-practices -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/seo-best-practices/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill seo-best-practices -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/seo-best-practices/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Mindrally/skills seo-best-practices
```

2. **Manually: put the files in place**
- File: `.github/skills/seo-best-practices/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill seo-best-practices -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Mindrally/skills --path seo-best-practices
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/seo-best-practices/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill seo-best-practices -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- generate dynamic metadata using `generateMetadata` in Next.js
- embed JSON-LD structured data for rich snippets
- reduce layout shifts and improve Core Web Vitals with React Server Components
- configure Open Graph, Twitter Cards, and canonical tags
- implement semantic markup, sitemaps, and robots.txt

## Example prompts
- Configure dynamic Open Graph and Twitter Card metadata for Next.js product pages
- Add JSON-LD structured data and fix heading hierarchy across the blog template
- Refactor this client view into React Server Components wrapped in Suspense to improve Core Web Vitals

# SEO Best Practices

You are an expert in SEO (Search Engine Optimization) for modern web applications. Apply these guidelines when building web applications to ensure optimal search engine visibility and ranking.

## Core SEO Principles

- Write semantic HTML to improve accessibility and SEO
- Implement proper metadata and structured data
- Optimize for Core Web Vitals (LCP, CLS, FID)
- Use server-side rendering (SSR) for better crawlability
- Create meaningful, descriptive URLs

## Metadata Implementation

### Next.js Applications
- Use the built-in `metadata` object or `generateMetadata` function for dynamic SEO
- Implement Open Graph and Twitter Card meta tags
- Create dynamic metadata based on page content
- Include canonical URLs to prevent duplicate content issues

### Nuxt.js Applications
- Use `useHead` and `useSeoMeta` composables for SEO metadata
- Implement SEO best practices using Nuxt's built-in composables
- Leverage auto-generated meta tags where appropriate

## Technical SEO Requirements

### Performance Optimization
- Minimize 'use client', 'useEffect', and 'setState'; favor React Server Components (RSC)
- Wrap client components in Suspense with fallback
- Use dynamic loading for non-critical components
- Optimize images: use WebP format, include size data, implement lazy loading
- Implement proper caching strategies

### Content Structure
- Use proper heading hierarchy (h1-h6)
- Include descriptive alt text for all images
- Create meaningful link text (avoid "click here")
- Implement structured data (JSON-LD) for rich snippets
- Use semantic HTML elements (header, main, nav, article, section, aside, footer)

### URL and Routing
- Use lowercase with dashes for URLs (kebab-case)
- Create descriptive, keyword-rich URLs
- Implement proper 301 redirects for moved content
- Create XML sitemaps and robots.txt
- Use canonical tags for duplicate content

### Mobile and Accessibility
- Design mobile-first responsive layouts
- Ensure sufficient color contrast for text
- Provide keyboard navigation for interactive elements
- Implement ARIA labels where semantic HTML is insufficient
- Ensure fast loading on mobile networks

## Image SEO

- Always include descriptive alt text for images
- Use appropriate image formats (WebP preferred)
- Implement lazy loading for below-the-fold images
```
